abstract = {Neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), frontotemporal dementia (FTD), amyotrophic lateral sclerosis (ALS), and multiple sclerosis (MS) often exhibit a prolonged presymptomatic phase during which neuropathological changes silently progress. Recent advances in biomarker research have revealed molecular and imaging signatures that precede clinical onset by years, offering a critical window for early intervention. This review synthesizes current knowledge on the most promising presymptomatic biomarkers across these conditions, highlighting their biological origins, diagnostic performance, and clinical utility. Particular emphasis is placed on the development and validation of biomarker panels, which combine multiple markers to enhance diagnostic sensitivity and specificity, enabling more accurate detection of disease in its earliest stages. Minimally invasive approaches, such as blood-based assays, are also discussed for their potential to facilitate widespread screening and longitudinal monitoring. As these biomarkers begin to integrate into clinical workflows, particularly in AD and MS, international collaboration will be essential to standardize methodologies and ensure equitable implementation. Ultimately, presymptomatic biomarkers hold transformative potential for shifting neurology toward a proactive and precision-based paradigm.},

This review systematically summarizes current understanding of fatty acid metabolism and its diverse implications in NDD pathology. Short-chain fatty acids (SCFAs), primarily generated by gut microbiota, regulate neuroinflammation, gut-brain communication, and blood-brain barrier (BBB) integrity via epigenetic modifications and immune modulation. Medium-chain fatty acids (MCFAs) exhibit therapeutic potential by improving energy metabolism and neuromuscular function, particularly in ALS models. Long-chain polyunsaturated fatty acids (PUFAs), notably docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), contribute to neuronal membrane integrity, synaptic plasticity, and antioxidant defense, mitigating oxidative stress and neuroinflammation. Conversely, saturated and certain n-6 fatty acids may exacerbate neurodegeneration through pro-inflammatory and oxidative pathways. Emerging evidence highlights fatty acid involvement in key pathological processes such as lipid peroxidation, mitochondrial dysfunction, ferroptosis, and BBB disruption. Therapeutically, targeted supplementation, dietary modification, microbiome manipulation, and advanced nanotechnology-based delivery systems are promising strategies. Nevertheless, precise therapeutic efficacy depends critically on disease stage, dosage, genetic background, and individual metabolic context. Integrating personalized medicine with precision nutritional strategies and novel drug-delivery platforms offers promising avenues to translate fatty acid-based interventions into clinical practice, potentially improving patient outcomes in the aging global population.},

While VCP mutations are well established as causing inclusion body myopathy, Paget's disease of bone, frontotemporal dementia, and amyotrophic lateral sclerosis, their role in cardiomyopathy remains underrecognized. This review aims to evaluate the pathophysiology, diagnostic approach, and management of VCP-associated cardiomyopathy to provide a framework for clinical care and future research. Emerging evidence from animal models and human case studies suggests that VCP dysfunction disrupts cardiomyocyte homeostasis, impairs protein degradation, and alters mitochondrial function, leading to maladaptive cardiac remodeling and susceptibility to dilated or hypertrophic cardiomyopathy. Echocardiographic studies in patients with VCP variants reveal a significant prevalence of diastolic dysfunction, conduction abnormalities, and variable degrees of systolic impairment. Despite these findings, there are no standardized guidelines for the diagnosis and management of VCP-associated cardiomyopathy. Current treatment strategies are extrapolated from heart failure guidelines, incorporating neurohormonal blockades with angiotensin-converting enzyme inhibitors, beta-blockers, and mineralocorticoid receptor antagonists. Our review highlights the need for systematic screening protocols, genotype-phenotype correlation studies, and the development of targeted therapies. Future research should focus on identifying biomarkers for early detection, elucidating the molecular mechanisms underlying cardiac dysfunction, and assessing the efficacy of novel treatment strategies. Recognizing VCP-associated cardiomyopathy as a distinct clinical entity will facilitate earlier diagnosis, improve patient outcomes, pave the way for disease-specific therapeutic interventions and insights into the mechanism for isolated cardiomyopathy.},

abstract = {Though usually described as isolated models, neurodegenerative diseases exist in a significant proportion of cases as mixed pathologies, particularly in older adults. The presence of co-pathologies may influence phenotypes and progression, and the correct classification in vivo has proven to be challenging, particularly without proper biomarker panels. Recent breakthroughs in biomarkers, enabling earlier detection in Alzheimer's disease and, more recently, in synuclein-related diseases, are promising as a first step toward the wider detection of all other abnormal proteins involved in neurodegenerative diseases. Over the past decade, the growing body of research on TDP-43 pathology has led to considering TDP-43 as a potential major contributor to the neurodegenerative process. TDP-43's normal function is essential for neuronal survival and the regulation of RNA processing and cellular stress response; abnormal TDP-43 protein leads to altered cell function and survival. TDP-43 is notably the neuropathological hallmark of amyotrophic lateral sclerosis (ALS) as well as some form of frontotemporolobar degeneration (FTLD). Tauopathies, divided in primary or secondary tauopathies cover other forms of FTLD including Pick disease (PiD), corticobasal degeneration (CBD), progressive supranuclear palsy (PSP) but also non-FTLD diseases like Alzheimer's disease (AD) which can be classified as secondary tauopathy. As the importance of copathology is more and more recognized, TDP-43 is also frequently observed in conjunction with other proteinopathies, possibly with a synergistic or additive effect, although the exact mechanism is still unclear. In Alzheimer's disease, the limbic predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) co-occurrence with Alzheimer's disease neuropathologic changes (ADNC) lead to a more rapid course. Although there are currently no approved and validated biomarkers for its early detection, several promising tools, including neuroimaging and biofluid biomarkers, are under development, offering hope for the earlier detection of TDP-43 pathology in vivo. Accurate identification of the underlying proteinopathies and pathological processes could lead to better diagnosis and classification, more precise selection of clinical trial candidates, and ultimately, disease-specific tailored treatments.},

abstract = {As so many drugs have failed in ALS a new approach is needed. The author proposes that recent human genetic variants may play major roles in the disease, changing metabolism. Evolution of hominins was accelerated 3-2.5 Mya, by cytidine monophospho-N-acetylneuraminic acid hydroxylase (CMAH) becoming a unitary pseudogene after a pathogenic infection, changing the sialome, and hence metabolism, brain development and neuromuscular junctions (NMJs). This was when hominins evolved to run in Africa and develop bigger brains. Deletion of CMAH in mice allows them to run for longer (~50%). The enzyme CMAH is critical for the sialome, particularly the neurotrophin GM1, a critical hub for viral infection and for NMJ stability, but which is lost from NMJs at the beginning of denervation, probably due a 10-fold increase in spinal cord glucosylceramidases (non-lysosomal GBA2). A GBA2 inhibitor, ambroxol, is currently in phase II for ALS. Human-specific GM1 may be critical for human evolution, lactate metabolism and ALS. Lipid/lactate metabolism changed to support these evolutionary changes and lactate is a major body/brain fuel, but compromised in ALS patients and a marker of disease progression. Recent progress in sports science involving lactate metabolism and human performance may also be relevant to ALS therapies, and incidence.},

This review highlights advances in the derivatization of various sesquiterpene lactones, quinones, and alcohols, particularly in targeting cancer and neurodegenerative diseases. The structural modifications discussed include the incorporation of triazole, arylidene, or thiol moieties with eudesmane, guaiane, and germacranolide-type sesquiterpenes, among others. In addition, the conjugation with chemotherapeutics, as well as the development of nanoscale therapeutics, is also discussed. Such modifications have expanded the pharmacological potential, enabling improved specificity, cytotoxicity profiles, and sensitization toward tumor cells. Additionally, sesquiterpenes such as parthenolide (20), pterosinsade A (176), and cedrol (186) have demonstrated potential in mitigating neurodegeneration via anti-inflammatory and antioxidant signaling pathway-modulation mechanisms, with potential applications in Alzheimer's, Parkinson's, and ALS diseases. Mechanistic insights into redox signaling modulation, NF-κB inhibition, ROS regulation, and disruption of aggregation underscore their multifaceted modes of action. This review highlights the translational promise of sesquiterpene derivatives as dual-action agents for potential drug development in a plethora of diseases that are caused by inflammation and free-radical damage.

While traditionally considered a final common pathway for motor deficits, accumulating evidence demonstrates that NMJ dysfunction is an early and critical driver of disease onset and progression in conditions such as amyotrophic lateral sclerosis and Charcot-Marie-Tooth disease. This review highlights shared and disease-specific mechanisms contributing to NMJ impairment, including presynaptic, postsynaptic, and perisynaptic Schwann cell defects in these diseases. We also discuss age-related changes at the NMJ, emphasizing its role in sarcopenia and muscle weakness in older adults. Furthermore, we explore emerging molecular drivers of NMJ dysfunction uncovered through studies in congenital myasthenic syndromes, autoimmune disorders, and advanced omics approaches. By integrating insights across diseases and aging, we underscore the potential for shared therapeutic strategies aimed at stabilizing NMJ function. Promising interventions targeting presynaptic neurotransmitter release, postsynaptic excitability, and perisynaptic Schwann cells are discussed as avenues to improve neuromuscular transmission and maintain muscle strength. Finally, we discuss the challenges and opportunities in translating these mechanistic insights into clinical therapies and highlight how novel human neuromuscular organoid models and advanced molecular profiling can bridge this gap. Together, these insights establish the NMJ as a critical, modifiable target for preserving motor function across neuromuscular diseases and aging.},

METHODS: This scoping review was conducted according to the preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews. An electronic search of databases, including Ovid MEDLINE(R), Embase (Ovid), APA PsycINFO (Ovid), and CINAHL was conducted. Title, abstract, and full text screening were completed using Covidence (Veritas Health Innovation, Melbourne, Australia) by two reviewers.

RESULTS: After deduplication, 1336 studies underwent title and abstract screening. Of these, the full texts of 65 studies were reviewed, and 23 were included. Three distinct topics were identified in the search: (i) message banking, in which discrete messages or phrases are recorded for later use, without the ability to create novel phrases outside of those previously recorded; (ii) voice banking, in which all the necessary phonemes in the target language are captured, with the goal of generating a personalized synthetic voice that can generate novel phrases; (iii) and voice conversion or voice reconstruction, in which pathologic voices or speech are "converted" into a personalized synthetic voices.

DISCUSSION AND CONCLUSION: This scoping review summarized the evidence for voice banking technology use in people diagnosed with dysphonia and dysarthria and sought to understand the research landscape of existing types of voice banking technology and software use in a clinical setting. The included papers were highly heterogeneous in terms of the population and type (research vs clinical program vs review/other). There is a pressing need for the publication of clinical programs and models facilitating the adoption of voice banking, especially within populations affected by conditions such as amyotrophic lateral sclerosis and laryngectomy, to address existing gaps and foster broader implementation and accessibility.},

OBJECTIVE: To estimate the incidence and prevalence of frontotemporal dementia and its clinical variants in the overall population and age subgroups.

We systematically searched PubMed, EMBASE, and Scopus between January 1, 1990, and October 22, 2024, for population-based studies estimating the incidence and/or prevalence of FTD.

DATA EXTRACTION AND SYNTHESIS: Studies and data were screened and extracted independently by 2 investigators in accordance with PRISMA guidelines. Incident and prevalent cases together with the population at risk were pooled using random-effects meta-analysis. Differences in heterogeneity by FTD variants and populations at risk were estimated.

MAIN OUTCOMES AND MEASURES: Prevalent and incident cases as numerator were based on well-defined clinical criteria. Denominators were derived either from census population data or from author-defined populations at risk.

RESULTS: From 1854 screened articles, 32 eligible population-based studies were identified. Sixteen were on prevalence and 22 on incidence reporting FTD measures, including those with estimates for the whole population and for specific age subgroups. Pooled crude incidence for FTD was 2.28 (95% CI, 1.55-3.36) per 100 000 person-years and prevalence, 9.17 (95% CI, 3.59-23.42) per 100 000 people. The behavioral-variant FTD pooled crude incidence was 1.20 (95% CI, 0.67-2.16) per 100 000 person-years and prevalence, 9.74 (95% CI, 2.90-32.73) per 100 000 people. The primary progressive aphasia variant pooled crude incidence was 0.52 (95% CI, 0.35-0.79) per 100 000 person-years and prevalence, 3.67 (95% CI, 3.05-4.43). FTD incidence among individuals younger than 65 years was 1.84 (95% CI, 0.79-4.30) per 100 000 person-years and prevalence, 7.47 (95% CI, 4.13-13.49) per 100 000 people. The denominator based on census data showed less heterogeneity than the population at risk defined by the authors (I2: for incidence, 91.6% vs 97.6%, respectively, and for prevalence, 98.8% vs 99.2%, respectively).

CONCLUSIONS AND RELEVANCE: In this systematic review and meta-analysis, estimates indicate that FTD is comparable in frequency to dementia with Lewy bodies and occurs at higher rates than progressive supranuclear palsy, corticobasal syndrome, and amyotrophic lateral sclerosis. These results provide a foundation for future research and public health strategy, especially for underrepresented populations, to better comprehend the global burden of FTD. Our findings provide robust pooled estimates of the incidence and prevalence of FTD and its subtypes, offering a foundation for future research and public health planning.},

Findings showed that the prevalence of binge-eating disorder in obesity treatment-seeking samples exceeds community norms. Results corroborate prior research suggesting that high body weight and eating pathology frequently co-occur and that individuals seeking weight management may be a high-risk population for both sub- and full-threshold eating disorders. Although concerns persist that weight loss efforts may promote or worsen eating disorder symptoms, research indicates that structured, evidence-based interventions typically have neutral or positive effects on disordered eating outcomes. However, rigorous and consistent screening for eating disorders among individuals with high weight is lacking. Importantly, obesity and eating disorders share many common etiological factors, suggesting that integrated intervention is both feasible and highly beneficial. Despite this, the fields of obesity and eating disorders remain siloed. This bifurcation disproportionately impacts youth and adolescents who are at high risk for the onset of both conditions. Currently, standards of care fail to include screening for eating disorders, particularly in youth with high weight, who may be overlooked or misdiagnosed due, in part, to weight-based stigma. Universal, developmentally sensitive screening tools and comprehensive assessment of eating disorder risk factors are urgently needed in pediatric primary care settings. As evidence mounts for concurrent treatment models of high weight and eating disorders, integration across science and clinical care is vital to improve outcomes for youth affected by both conditions.},

abstract = {Neuroinflammation is now being identified as the major factor in the development of various neurological disorders. It is a vital process in neurons and the brain that maintains homeostasis under normal and healthy conditions. However, in hyperactivated states, neuroinflammation can also go awry when microglia and astrocytes enter a toxic, reactive state that can release chemicals that damage neurons. When innate immune cells encounter pathogens, infection, cell debris, or misfolded proteins, they release certain chemokines and cytokines to eliminate the intruding particles and protect the brain. However, persistent inflammatory reactions are harmful and can lead to neurodegeneration by continuously releasing toxic chemicals and proteins. Chitinase-3-like protein 1 (CHI3L1), a secretory protein, is emerging as a key inflammatory molecule that is strongly upregulated during neuroinflammation and has been implicated in the pathogenesis of many diseases. The brain's activated astrocytes are the main source of CHI3L1 and are a dependable biomarker for inflammatory pathologies affecting the central nervous system (CNS), including neurodegeneration and autoimmune diseases. The protein has been implicated in many neurological disorders, including Alzheimer's Disease, Parkinson's Disease, Amyotrophic Lateral Sclerosis, and others, mediating neuroinflammation and neurodegeneration. CHI3L1 has contrasting functions in the CNS and other tissues. While the protein promotes cell proliferation and migration in various non-neuronal cancers, at the same time, it simultaneously promotes neurodegeneration and apoptosis in the CNS. This paper reviews the current developments in our knowledge of the pathogenic role of the CHI3L1 protein in various neurological disorders.},

Emerging evidence indicates that hexokinase (HK), the rate-limiting glycolytic enzyme, functions as a master regulator orchestrating neuronal survival through metabolic‒mitochondrial coupling. This review consolidates emerging paradigms revealing that HK maintains neuronal viability through its obligate interaction with mitochondrial VDAC1, forming a metabolic checkpoint that integrates energy status with survival signaling. Disease-specific HK dysfunction patterns precede clinical manifestations and drive pathological cascades across primary neurodegenerative conditions. Pathological proteins characteristic of neurodegeneration-amyloid-β in AD, α-synuclein in PD, mutant SOD1 in ALS, and huntingtin in HD-converge to disrupt the HK-VDAC1 axis through distinct molecular mechanisms, triggering mitochondrial permeabilization, bioenergetic collapse, and inflammatory activation. This uncoupling event promotes VDAC1 oligomerization, enabling the cytosolic release of mtDNA, which in turn activates the NLRP3 inflammasome while depleting antioxidant capacity, establishing self-perpetuating neuroinflammatory cycles. The literature reveals that HK functions as a molecular rheostat, determining neuronal fate through glucose-6-phosphate-mediated feedback control, modulation of growth factor signaling, and regulation of apoptosis/survival pathways. Therapeutic targeting of HK through peptide interventions, enzymatic modulation, and gene therapy demonstrates robust neuroprotective effects across multiple disease models. Meanwhile, combination strategies addressing metabolic-inflammatory networks show synergistic efficacy. These insights position HK as a convergent therapeutic nexus offering unprecedented opportunities for precision intervention in neurodegeneration, with potential for early diagnostic applications and preventive strategies that could transform treatment paradigms for conditions affecting millions worldwide.},

This review first comprehensively explores the multifaceted mechanisms by which mitochondria mediate ferroptosis in neurological diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), Friedreich's ataxia (FRDA), amyotrophic lateral sclerosis (ALS), epilepsy, stroke, and brain injury, with a focus on mitochondrial lipid peroxidation and iron metabolism dysregulation. Building on these mechanistic insights, we further discuss emerging evidence suggesting that targeting mitochondrial pathways may represent a promising therapeutic strategy for mitigating ferroptosis-associated neuronal damage. By synthesizing these findings, our review establishes a conceptual foundation for developing innovative neuroprotective interventions through precise modulation of mitochondrial function within ferroptotic pathways.},

abstract = {The human genome contains a substantial legacy of ancient retroviral infections known as Human Endogenous Retroviruses (HERVs), composing 8 % of our DNA. In healthy young individuals, these elements are kept dormant by robust epigenetic mechanisms, primarily DNA methylation and repressive H3K9me3 histone marks. However, this epigenetic silencing deteriorates with age, leading to the reactivation of HERVs, particularly the youngest HERV-K subfamily. This report posits that this HERV awakening is not a passive byproduct of aging but an active, transmissible driver of pathology. The reactivation of HERVs leads to the production of retrovirus-like particles (RVLPs) that can induce senescence in healthy neighboring cells, propagating a contagious aging phenomenon. Furthermore, the accumulation of HERV-derived dsRNA and reverse-transcribed DNA triggers chronic innate immune responses through pathways including cGAS-STING and IFIH1-MAVS, fueling the systemic, low-grade inflammation characteristic of inflammaging, catalytically accelerated by exogenous viral infections. Pathogens such as SARS-CoV-2, Epstein-Barr Virus (EBV), and Herpes Simplex Virus (HSV-1) can directly transactivate HERVs via their own viral proteins, overwhelming the already compromised epigenetic controls in an aging host. This mechanistic link between viral triggers and endogenous retroviral activity is strongly implicated in a range of age-related diseases, including neurodegenerative disorders such as Alzheimer's disease and Amyotrophic Lateral Sclerosis (ALS), where the HERV-K envelope protein is directly neurotoxic. It is also linked to autoimmune diseases like Multiple Sclerosis and various cancers. This report synthesizes these findings and identifies a novel mechanistic link between viral activity, chronic inflammation, and the onset of age-related diseases.},

abstract = {Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder that progressively affects upper and lower motor neurons, leading to symptoms including dysarthria, muscle weakness, and paralysis. The disease is multifactorial, with a variety of contributing pathways, including excitotoxicity, oxidative stress, and neuroinflammation. Current treatments target only two of these pathways with limited efficacy, highlighting the need for alternative approaches. Increasing evidence highlights the involvement of immune dysregulation, particularly microglial-mediated neuroinflammation, in ALS pathology. Fortunately, many immunomodulatory drugs acting on microglia are already available for other diseases, indicating promising opportunities for drug repurposing. This literature review provides an overview of existing drugs under investigation for ALS, including those that have failed, and highlights new microglia-targeting candidates with repurposing potential. Compounds such as ibudilast, fingolimod, and modafinil have shown encouraging initial clinical results, whereas others were well-tolerated but underpowered or failed to demonstrate efficacy. New candidates, such as azithromycin, naltrexone, montelukast, doxycycline, tofacitinib, quercetin, belinostat, and several kinase inhibitors, have demonstrated positive preclinical results, supporting their advancement toward clinical evaluation. Overall, these findings emphasize the potential of microglia-targeting therapies for ALS. To realize this potential, future studies must include larger cohorts, assess effects across disease stages and patient subgroups, and examine sex differences. This is essential to address patient heterogeneity and improve personalized treatment in ALS.},

This single-protein paradigm has guided therapeutic development for decades; yet clinical outcomes remain modest. Mounting evidence, however, reveals that protein aggregates rarely occur in isolation; instead, they coexist, colocalise, and modulate each other's pathogenicity. Here, we propose a co-proteinopathy framework that views neurodegeneration as an interactive network of misfolded proteins rather than as isolated disorders. Adopting this framework demands multiplexed quantification of protein aggregates and disease models that better reflect the biological complexity of human neurodegeneration. The co-proteinopathy perspective offers a more realistic foundation for next-generation approaches to neurodegeneration research and treatment.},

Despite intensive research, its pathogenesis remains poorly understood. Recent insights suggest a pivotal role of the gut microbiota in modulating neuroinflammation and neurodegeneration via the gut-brain axis. This systematic review aims to synthesize clinical evidence on gut microbiota dysbiosis in ALS, exploring microbial and metabolic alterations and their associations with disease progression and severity. A comprehensive literature search was conducted across PubMed, Embase, Scopus, Web of Science, and other databases up to May 10, 2024, adhering to PRISMA 2020 guidelines. Eighteen eligible human studies were selected based on predefined inclusion criteria. Data on microbial diversity, taxonomic shifts, metabolite profiles, and clinical correlations were extracted and assessed using a modified Newcastle-Ottawa Scale. Most studies reported altered microbial diversity, reduced butyrate-producing bacteria (e.g., Faecalibacterium, Roseburia), and increased pro-inflammatory taxa (e.g., Escherichia coli, Bacteroides) in ALS. Integrated microbiome-metabolome analyses revealed disruptions in SCFAs, bile acids, and lipid metabolism, some correlating with ALSFRS-R scores and cognitive impairment. Although some studies showed minimal or no differences, the overall evidence supports a link between dysbiosis and ALS pathophysiology. Probiotic trials demonstrated limited efficacy, highlighting the need for targeted, patient-specific interventions. Gut microbiota dysbiosis is increasingly recognized as a contributor to ALS progression. However, methodological variability, small sample sizes, and limited longitudinal data restrict definitive conclusions. Future research should employ standardized, multi-omics approaches and larger cohorts to clarify causal links and develop microbiome-informed diagnostics and therapies for ALS.},

Preclinical studies suggest that neuromuscular junction dysfunction develops early in ALS, and pyridostigmine may temporarily improve neuromuscular transmission. However, altered neuromuscular junction transmission has uncertain benefits in ALS progression. Pyridostigmine does not have other plausible mechanisms that truly modify ALS pathophysiology. People with ALS (PALS) who have positive acetylcholine receptor autoantibodies and no myasthenia symptoms are unlikely to respond to pyridostigmine treatment. Clinical trials on pyridostigmine in PALS are lacking, but two clinical trials of other similar anticholinesterase agents did not effectively slow ALS progression. Muscarinic cholinergic side effects, including gastrointestinal symptoms, are common. Given the lack of mechanistic plausibility and efficacy, we do not support the use of pyridostigmine for slowing ALS progression.},

abstract = {The pathophysiology of neurodegenerative diseases is largely driven by ER stress, contributing to cellular dysfunction and inflammation. Chronic ER stress in skeletal muscle is associated with a deterioration in muscle function, particularly in diseases such as ALS, PD, and AD, which are often accompanied by muscle wasting and weakness. ER stress triggers the UPR, a cellular process designed to restore protein homeostasis, but prolonged or unresolved stress can lead to muscle degeneration. Recent studies indicate that exercise may modulate ER stress, thereby improving muscle health through the enhancement of the adaptive UPR, reducing protein misfolding, and promoting cellular repair mechanisms. This review examines the influence of exercise on the modulation of ER stress in muscle cells, with a particular focus on how physical activity influences key pathways contributed to mitochondrial function, protein folding, and quality control. We discuss how exercise-induced adaptations, including the activation of stress-resilience pathways, antioxidant responses, and autophagy, can help mitigate the negative effects of ER stress in muscle cells. Moreover, we examine the potential therapeutic implications of exercise in neurodegenerative diseases, where it may improve muscle function, reduce muscle wasting, and alleviate symptoms associated with ER stress. By integrating findings from neurobiology, muscle physiology, and cellular stress responses, this article highlights the therapeutic potential of exercise as a strategy to modulate ER stress and improve muscle function in neurodegenerative diseases.},

Emerging evidence indicates that gut microbiome dysbiosis significantly impacts REDs by regulating various biochemical pathways. Alterations in microbial diversity and composition have been observed across multiple REDs; however, a comprehensive understanding of the complete scenario remains a significant challenge. To elucidate these dynamic interactions, future research should utilize multifaceted approaches. This review focuses on the key modifications in the gut microbiome that contribute to the pathogenesis of REDs and discusses potential gut microbiome-targeted therapeutic strategies that could be effectively employed to treat these disorders.},

abstract = {PURPOSE OF REVIEW: This review aims to explore the distinct clinical characteristics, epidemiology, treatment approaches, and research needs concerning cardiac arrest in the intensive care unit (ICU-CA), a specific subset of in-hospital cardiac arrest (IHCA). While IHCA remains a major cause of mortality, recent data indicate improved outcomes, with a notable variation in incidence and survival depending on the location, particularly within the ICU setting.

RECENT FINDINGS: Recent studies underscore that ICU-CA differs significantly from general IHCA in etiology, monitoring, and treatment environment. Although incidence rates vary widely (4-78 per 1000 ICU admissions), recent data suggest a stabilization. Causes of ICU-CA often involve noncardiac factors such as septic shock and respiratory failure. Treatment is typically guided by general advanced life support (ALS) protocols, but ICU-specific resources such as real-time monitoring, invasive pressure measurements, transesophageal echocardiography, and the potential for extracorporeal cardiopulmonary resuscitation offer unique advantages. The COVID-19 pandemic highlighted the vulnerability of ICU patients, with respiratory causes dominating and extremely poor outcomes reported.

SUMMARY: In summary, ICU-CA represents a distinct clinical entity requiring tailored research. Future directions should prioritize international registries, validation of predictive models using artificial intelligence, and clarification of do-not-resuscitate practices to improve outcomes and resource allocation in this critically ill population.},

Berberine (BBR) is an isoquinoline alkaloid that occurs naturally and has been proposed as a potential neuroprotectant, since it has been found to exert multiple effects to modulate most of the pathological hallmarks of NDs, including neuroinflammation, oxidative stress, mitochondrial dysfunction, and protein aggregation. Although it shows promise, the practical utilization of BBR is marred by low oral bioavailability, high rate of oxidation, and low blood-brain barrier permeability. To combat these issues, recent developments in nanotechnology, especially in the use and creation of lipidic, inorganic, and polymeric nano-particles, have dramatically altered the pharmacokinetics and pharmacodynamics of BBR. This article summarizes recent advances in BBR-based nanoformulations and emphasizes the translational potential of BBR-based nanopreparations to improve treatment response in NDs. It also describes the molecular foundation of the neuroprotective effects of BBR and its possible place in clinical practice. Future nanocarrier development and investigation of BBR mechanisms will be essential to the development of the next generations of therapeutics in NDs.},

abstract = {INTRODUCTION: This study aims to systematically evaluate the diagnostic efficacy of Transformer-based multimodal fusion deep learning models in early Alzheimer's disease (AD) through a Meta-analysis, providing a scientific basis for clinical applications.

METHODS: Following PRISMA guidelines, databases such as PubMed and Web of Science were searched, and 20 eligible clinical studies (2022-2025) involving 12,897 participants were included. Study quality was assessed using the modified QUADAS-2 tool, statistical analyses were performed with Stata 16.0, effect sizes were pooled via random-effects models, and subgroup analyses, sensitivity analyses, and publication bias tests were conducted.

RESULTS: Results showed that Transformer-based multimodal fusion models exhibited excellent overall diagnostic performance, with a pooled AUC of 0.924 (95% CI: 0.912-0.936), sensitivity of 0.887 (0.865-0.904), specificity of 0.892 (0.871-0.910), and accuracy of 0.879 (0.858-0.897), significantly outperforming traditional single-modality methods. Subgroup analyses revealed that: Three or more modalities achieved a higher AUC (0.935 vs. 0.908 for two modalities, p =0.012). Intermediate fusion strategies (feature-level, AUC=0.931) significantly outperformed early (0.905) and late (0.912) fusion (p <0.05 for both). Multicenter data improved AUC (0.930 vs. 0.918 for single-center, p =0.046), while sample size stratification (<200 vs. ≥200 cases) showed no significant difference (p =0.113). Hybrid Transformer models (Transformer +CNN) trended toward higher AUC (0.928 vs. pure Transformer 0.917, p =0.068) but did not reach statistical significance.

DISCUSSION: Notable studies included Khan et al.'s (2024) Dual-3DM[3]AD model (AUC=0.945 for AD vs. MCI) and Gao et al.'s (2023) generative network (AUC=0.912 under data loss), validating model robustness and feature complementarity. Sensitivity analysis confirmed stable results (AUC range: 0.920-0.928), and Egger's test (p =0.217) and funnel plot symmetry indicated no significant publication bias. Limitations included a high proportion of single-center data and insufficient model interpretability. Future research should focus on multicenter data integration, interpretable module development, and lightweight design to facilitate clinical translation. Transformer-based multimodal fusion models demonstrate exceptional efficacy in early AD diagnosis, with multimodal integration, feature-level fusion, and multicenter data application as key advantages. They hold promise as core tools for AD "early diagnosis and treatment" but require further optimization for cross-cohort generalization and clinical interpretability.},

This review highlights the critical role of the C5-C5aR1 axis, in the pathogenesis of neurodegenerative diseases such as AD and ALS. In AD and ALS, abnormal protein aggregates activate the complement system (CS), leading to increased production of C5a. C5a activates C5aR1 on microglia, triggering the release of pro-inflammatory cytokines (IL-1β, TNF-α, IL-6) that induce synaptic loss. Concurrently, the C5-C5aR1 axis impairs microglial phagocytic capacity, promoting damage-associated molecular patterns (DAMPs) accumulation and forming a vicious cycle of inflammation and complement activation. Additionally, excessive complement molecule assembles into the terminal complement complex (TCC), which exerts direct neurotoxic effects and drives neuronal apoptosis. Preclinical studies show that C5aR1 antagonists, such as PMX205, mitigate disease progression in AD and ALS animal models by reducing neuroinflammation and preserving synaptic function. These findings underscore the C5-C5aR1 axis as a promising target for neurodegenerative disease therapy and highlight the need for further development of potential antagonists of C5aR1.},

abstract = {PURPOSE OF REVIEW: Spinal cord injury (SCI) remains a disabling condition associated with long term neurological impairment, functional disability, and reduced quality of life. Despite decades of research, pharmacological interventions with proven clinical efficacy remain limited. This review critically evaluates the current evidence supporting riluzole as a neuroprotective agent for acute traumatic and nontraumatic SCI. We synthesize findings from preclinical and clinical studies, assess the progress towards clinical translation, and outline key challenges and research opportunities for future implementation.

RECENT FINDINGS: Riluzole, an FDA-approved agent for amyotrophic lateral sclerosis (ALS), inhibits voltage-gated sodium channels and modulates glutaminergic transmission, two mechanisms central to the pathogenesis of secondary injury in SCI and in nerve cell degeneration in nontraumatic forms of SCI, including degenerative cervical myelopathy (DCM). Preclinical studies consistently demonstrate functional and histopathological improvements following riluzole administration. Phase I/II trials have provided evidence for its safety and tolerability in acute SCI patients, while the RISCIS and CSM-PROTECT trials, two landmark multicenter randomized controlled studies, along with their secondary analyses, revealed promising multidomain improvements in motor function, independence, and quality of life indices. Sub-studies have also established pharmacokinetic and pharmacodynamic frameworks for individualized dosing, and early biomarker analysis suggests potential for predictive stratification.

SUMMARY: Riluzole represents a promising candidate for neuroprotection in traumatic and nontraumatic SCI. The consistency of favorable trends across multiple domains and strong support from preclinical studies highlight riluzole's value in orphan diseases such as SCI. Future directions should focus on refining the therapeutic window, optimizing PK/PD modeling, and identifying patient subgroups most likely to benefit. Its implementation in a multimodal treatment paradigm for acute SCI will be crucial for optimizing management protocols in this highly disabling condition.},

These proteins assemble into amyloid fibrils that undergo prion-like propagation and dissemination, ultimately inducing neurodegeneration. Understanding the biology of these protein aggregates is fundamental to elucidating the pathophysiology of neurodegenerative disorders. In this review, we summarize the molecular mechanisms underlying the aggregation and transmission of pathological proteins, the processes through which these protein aggregates trigger neurodegeneration, and the interactions between different pathological proteins.

abstract = {The idea that it might be possible to prevent some forms of amyotrophic lateral sclerosis and frontotemporal dementia has finally come of age. The hexanucleotide repeat expansion in the C9orf72 gene accounts for ∼10% of all amyotrophic lateral sclerosis and 10%-15% of all frontotemporal dementia diagnoses, with the two clinical syndromes co-manifesting in a significant number of patients. As a result, clinically unaffected carriers of pathogenic C9orf72 repeat expansions are currently the largest identifiable population at significantly elevated risk for both amyotrophic lateral sclerosis and frontotemporal dementia, and in whom it might be possible to prevent the emergence of clinically manifest disease. Strategies for the design of disease prevention trials among clinically unaffected C9orf72 carriers have begun to emerge separately in the amyotrophic lateral sclerosis and frontotemporal dementia fields. However, recognition of the need to define neurodegenerative diseases based on biology underscores the need to consider all potential clinical manifestations of a C9orf72 repeat expansion together, rather than the traditional siloed approach of focusing on only amyotrophic lateral sclerosis or only frontotemporal dementia. Indeed, emerging clinical and biological markers that might be used to quantify pre-symptomatic disease progression and to predict the short-term risk of phenoconversion to clinically manifest disease are shared across the phenotypic spectrum. Given the anticipated progress in the development of therapeutic strategies to target the C9orf72 repeat expansion, and the enthusiasm for prevention trials among the unaffected C9orf72 repeat expansion carrier population, now is the time to begin work on the design of disease prevention trials. To this end, The Association for Frontotemporal Degeneration and The ALS Association supported a multi-stakeholder workshop (in Washington D.C., June 2024) to unify efforts to design a prevention trial for the population at elevated genetic risk for the phenotypic spectrum of C9orf72 disease. Here we describe recommendations emanating from this workshop for the selection of outcome measures, delineation of eligibility criteria, optimal use of biomarkers and digital health technologies, potential analytic frameworks and relevant regulatory considerations related to C9orf72 disease prevention trials. We also emphasize the importance of the amyotrophic lateral sclerosis and frontotemporal dementia communities working together in partnership with the C9orf72 repeat expansion carrier community, the regulatory authorities and the broader drug development community.},

This review outlines the growing contribution of gut microbiota in the remediation of neurological health and also emphasizes the controlling role of gut microbiota on the synthesis of neurotransmitters. Emerging evidence indicates that dysbiosis of the gut is related to a variety of neurodegenerative and neuropsychiatric diseases such as Parkinson's disease (PD), Alzheimer's disease (AD), multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), autism spectrum disorders (ASD), depression, and glioblastoma. Mechanistic understandings show that gut microbes critically contribute to neuroimmune and blood-brain barrier (BBB) signaling. The peripheral association of gut microflora, networked with inflammasome activation, nuclear factor kappa B (NF-κB), and type-I IFN pathways highlights their role in CNS inflammation. Microbiota-targeted interventions with probiotics, prebiotics, synbiotics, antibiotics, dietary modifications, and fecal microbiota transplantation are examined for their therapeutic potential. These strategies appear to be promising to reinstate microbial balance, enhance neuroplastic responses, and ameliorate the disease symptoms. The review highlights personalized microbiome-based algorithms, underpinned by integrated multi-omics technologies and machine-learning-driven diagnostics. Future research should address underlying microbial mechanisms and perform large, randomized controlled trials in order to establish microbiota-based therapies for neurological disorders.},

abstract = {Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease leading to permanent damage to the central and peripheral motor neurons. Currently, there is no effective treatment for ALS, and therapy focuses solely on slowing the progression of the disease. Recent studies show that gut microbiota plays an important role in the development of neurodegenerative diseases. Altered gut microbiota has also been found in ALS. These changes have prompted the search for alternative forms of ALS treatment, focusing on changing the microbial composition of the gut. It has been noted that diet, probiotics, prebiotics and vitamins can all influence the course of ALS. Another interesting issue is fecal microbiota transplantation, which is already used in the treatment of certain intestinal diseases and could potentially be useful in the treatment of ALS. This review summarizes current knowledge on the impact of gut microbiota on the neurodegenerative process in ALS, with particular emphasis on the role of diet and probiotics. It also discusses potential mechanisms and highlights future research directions in this emerging field.},

abstract = {BACKGROUND: Consistent wear is essential for valid and reliable actigraphy data. Adherence to actigraphy may be challenging in primary school children due to developmental and design considerations, yet no quantitative synthesis of adherence in this age group exists.

OBJECTIVE: The aim of this study was to provide the first pooled estimate of actigraphy adherence in primary school-aged children and examine the impact of individual, device, and study-specific factors on adherence.

METHODS: We searched seven electronic databases for studies reporting adherence to actigraphy in primary school-aged children. Searches were conducted in Embase, MEDLINE, PsycINFO, Social Policy and Practice via OVID, Education Resources Information Center, British Education Index, and CINAHL via EBSCO using database-specific search strategies conducted between January 2018 and January 24, 2023. Forward and backward citation searches were completed on the Web of Science Core Collection and Google Scholar. Gray literature searches were undertaken in PsycEXTRA and Healthcare Management Information Consortium. Empirical studies reporting quantitative data on adherence to community-based actigraphy in children aged 5-11 years (or if ≥50% of the average age fell within this range) were included. Eligible studies were written in English and could be published or unpublished. Risk of bias was assessed using an 8-item checklist adapted from Berger et al's actigraphy reporting standards. All included studies were narratively synthesized, and adherence data were pooled in a proportional meta-analysis. Adherence was calculated as the proportion of children meeting wear-time criteria to be included in the analysis compared to the number of children invited to use the device at baseline. Meta-regression was used to examine the impact of individual, device, and study-specific factors on adherence. Prediction intervals were calculated to estimate the range of adherence expected across future studies.

RESULTS: Data were extracted from 235 studies (N=148,161); of these, 135 studies (n=64,541) provided adherence data for proportional meta-analysis. Pooled adherence, measured across 1-140 days, was 81.6% (95% CI 78.7%-84.4%; I2=98.8%). The prediction intervals (42.8%-100%) indicated substantial variability in adherence estimates across studies. Meta-regression suggested that individual characteristics contributed to observed heterogeneity as children with a physical health diagnosis (b=0.236, 95% CI 0.009-0.464; P=.04) and those with neurodevelopmental or mental health diagnosis (b=0.395, 95% CI 0.125-0.665; P=.004) demonstrated higher adherence than undiagnosed children, though these effects were of modest magnitude. No significant effects were found for age, placement, protocol length, protocol deviation, or incentivization. Reporting quality was poor, with only 3.4% of studies satisfying all criteria.

CONCLUSIONS: This review demonstrates generally high actigraphy adherence in primary school-aged children, particularly those with health conditions. However, observed variability indicates that adherence was much lower in some contexts, underscoring that the reported pooled adherence cannot be assumed across future actigraphy applications within this age group. Future research should use standardized adherence reporting and should plan for adherence variability.},

Beyond their canonical functions in genome defense, emerging evidence highlights piRNAs as key modulators of neuronal development, synaptic plasticity, axonal regeneration, and neuroimmune interactions-processes central to brain function and dysfunction. This review provides a comprehensive overview of piRNA biogenesis, molecular mechanisms, and regulatory pathways relevant to neurobiology. We focus on the growing body of evidence implicating piRNA dysregulation in major neurological and neuropsychiatric disorders, including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, stroke, glioma, autism spectrum disorder, and schizophrenia. Importantly, we discuss the neuropharmacological implications of piRNA pathways as novel targets for therapeutic intervention and their potential utility as biomarkers for early diagnosis and treatment stratification. By integrating mechanistic insights with emerging translational evidence, this review highlights piRNAs as promising molecular targets in the development of next-generation neurotherapeutics aimed at modifying disease progression and improving brain health.},

NfL, a structural component of axons, is released into cerebrospinal fluid (CSF) and blood following neuro-axonal damage. Highly sensitive immunometric assays have enabled its reliable quantification in blood, facilitating non-invasive monitoring. Several studies demonstrated strong correlations between NfL levels and the risk of developing different neurological diseases and, in individuals already living with a neurological disease, with the risk of worsening. However, interpretation is affected by factors like age, BMI, renal function, and comorbidities. NfL is already utilized as a diagnostic and prognostic biomarker in clinical practice, particularly in specialized centers and research settings, although no FDA-cleared assay is currently available for routine use. Recent research has highlighted that NfL may represent the first of a new generation of neurological biomarkers, with many more ready to come, such as glial fibrillary acidic protein (GFAP), further improving diagnostic and prognostic accuracy. Despite its promising role in the landscape of biomarkers, challenges remain to implement NfL in daily clinical practice, including standardization of assays, defining reference values, and ensuring methodological consistency. Addressing these limitations will be essential for integrating NfL into routine clinical practice, ultimately advancing precision medicine in neurology.},

Despite decades of research, effective treatments that halt or reverse these conditions remain elusive. Aging is the most significant risk factor in the development of these diseases, intertwining with molecular processes like DNA damage, mitochondrial dysfunction, and protein aggregation. Recent advances in gene-editing technologies, particularly CRISPR-Cas9, are beginning to shift the therapeutic landscape. This revolutionary tool allows for precise correction of genetic mutations associated with neurodegeneration, offering the potential for disease modification rather than symptom management alone. In this review, we explore how CRISPR-Cas9 is being leveraged to target key genes implicated in various neurodegenerative conditions and how it may overcome barriers posed by aging biology. We also examine the delivery systems and safety challenges that must be addressed before clinical application. With continued progress, CRISPR-Cas9 could mark a turning point in our ability to treat or even prevent age-related neurological decline.},

With their unparalleled proliferative capacity and near-pluripotent differentiation potential, iPSCs have become invaluable tools for investigating neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS). Neuronal models derived from ALS patient-specific iPSCs, particularly iPSC-derived motor neurons (iPSC-MNs), offer a robust platform to recapitulate disease-specific pathology and investigate the molecular mechanisms underpinning ALS, thereby accelerating the discovery of novel therapeutic strategies.

Evidence-informed care can improve outcomes, and guidelines play a key role in supporting this. A preliminary search showed limited guidelines exist, with none developed for the Australian context. This review aimed to identify existing health and social care guidelines for MND.

METHODS: A scoping review was conducted using Joanna Briggs Institute (JBI) methodology. Guidelines addressing health and social care for people with MND, gene carriers, family members, or carers were included regardless of publication status. Five databases and additional sources were searched. Two reviewers independently screened citations, and data were extracted and analysed descriptively, with qualitative content analysis grouping guideline questions. Reporting followed PRISMA-ScR.

RESULTS: Forty-two guidelines covering 133 questions were included. Most focused on symptom management for people with MND and were produced by professional bodies. Few used GRADE methodology or systematic reviews, and only seven assessed risk of bias. No guideline was developed for Australia.

CONCLUSIONS: A high-quality, evidence-based MND guideline following best practice development methods is needed.},

Whether TDP-43 phosphorylation is a pathological driver, or rather a protective antagonist of TDP-43 aggregation and consequently neurodegeneration, is still debated and a matter of ongoing research. Here, we review current knowledge about TDP-43 phosphorylation in disease and the kinases and phosphatases that regulate this post-translational modification. We discuss how TDP-43 phosphorylation is thought to shape TDP-43's phase separation, aggregation and toxicity in neurodegenerative diseases.

Deep learning (DL) for neuroimaging can improve early diagnosis and disease monitoring. Clinical implementation of DL faces challenges in accurately representing real-world data. Recent models, particularly those focused on diagnostic categorization, have achieved high accuracy, but their applicability to patients is limited. Conflicting inferences have been reported, with findings from small cohorts generalizing conclusions without considering inter-scanner, intra- and inter-site variations. A theoretically feasible method involves gathering a comprehensive dataset that encompasses all patient demographics, but this presents practical challenges including harmonization, data incompleteness, class imbalance, and substantial costs. Existing research has also mostly focused on common NDDs like Alzheimer's Disease (AD) and Parkinson's Disease (PD). This contribution expands the literature by looking at a wider range of NDDs, exploring the latest advancements in applying deep learning algorithms to neuroimaging analysis for the diagnosis and monitoring of NDDs, including AD, Frontotemporal Dementia (FTD), Lewy Body Dementia, PD, Huntington's Disease, Amyotrophic Lateral Sclerosis, and Multiple Sclerosis. We emphasize how these approaches are handling spatial/temporal information available in brain volume imaging data. We conclude by discussing the challenges associated with the use of voxel-based, patch-based, ROI-based, and slice-based approaches in brain volume imaging. These challenges are further compounded by issues such as inter-site and inter-scanner variability, class imbalances in medical datasets, and the scarcity of accurately annotated data, all of which impact the performance and generalizability of deep learning models.},

These changes can be visualized in vivo on a cellular and subcellular level using optical coherence tomography (OCT). This article summarizes which retinal changes occur and how these could be used as potential biomarkers of neurodegenerative diseases.

OBJECTIVE: The article gives an overview of the literature on the relationship between neurodegeneration, OCT-based retinal characteristics and cognitive functions.

METHODS: A literature search was carried out in PubMed until February 2025. The search terms "neurodegeneration", "dementia", "mild cognitive impairment", "mild neurocognitive disorder", "OCT", "OCT angiography (OCT-A)", "retinal biomarkers", "retinal layer", "RNFLT", and "GCL" were used. Relevant publications were reviewed, analyzed and summarized.

RESULTS: In OCT‑A Alzheimer's disease, frontotemporal dementia, vascular dementia, amyotrophic lateral sclerosis, multiple sclerosis (MS) and Parkinson's disease demonstrate an association with a reduced retinal nerve fiber layer (RNFL) and the ganglion cell layer (GCL) thickness as well as an enlarged foveal avascular zone.

CONCLUSION: So far retinal changes could not be specifically assigned to a particular form of neurodegenerative disease,; however, they could be meaningful in neuropsychological/radiological examinations and for longitudinal monitoring, as already recommended for MS. Further longitudinal studies are needed to identify and validate retinal biomarkers (patterns).},

Sensitivity analyses excluded the largest study with imputed data and included a sensitivity-only model. PRISMA-DTA compliant; PROSPERO CRD42025623678.

RESULTS: Nine studies (n = 9656), all from ALS referral centers, were included. GCC showed higher sensitivity (∼95 %) than rEEC and AC Probable+ (59 % and 54 %) and Possible+ (84 % and 85 %), but lower specificity (66 %) vs. rEEC (Probable+ 94 %, Possible+ 77 %) and AC (Probable+ 94 %, Possible+ 82 %). GCC achieved the highest AUC (0.95) and diagnostic odds ratio (36.1). Sensitivity-only analysis confirmed GCC performance (97 %).

CONCLUSIONS: GCC demonstrated superior sensitivity, potentially facilitating earlier recognition and trial inclusion. Their lower specificity requires caution, particularly in low-prevalence contexts. Applicability in unselected neurology populations remains uncertain.

SIGNIFICANCE: GCC may enable earlier ALS diagnosis and timely trial enrollment in referral centers.},

abstract = {Big tau is an isoform of tau that includes the large 4 A exon, resulting in an extended projection domain and an overall increase in apparent molecular weight from 40 to 65 kDa to 95-110 kDa. Its expression is highly restricted to the peripheral and autonomic nervous systems and select regions of the central nervous system. Although the precise function of Big tau remains unclear, we have proposed that the expanded projection domain of low molecular weight (LMW) tau by 250 amino acids of exon 4a and its structural properties may enhance axonal transport in long-projecting neurons and confer resistance to aggregation. Here, we propose a clinical perspective based on the properties of Big tau: the selective expression of Big tau in spinal motor neurons, but not in upper motor neurons or other spinal neuronal populations, is likely to make Big tau a specific biomarker for spinal motor neuron pathology. This expression pattern may be particularly valuable for tracking disease prognosis and progression in conditions such as amyotrophic lateral sclerosis (ALS) and related disorders, to identify when degeneration advances to lower motor neurons. Big tau could thus serve as a more specific biomarker to neurofilament or LMW tau proteins or can be used in combination with other biomarkers to enhance the specificity and sensitivity. This hypothesis can be readily tested using existing samples and assays applied to cerebrospinal fluid (CSF) and blood samples from patients. If validated through clinical studies, Big tau may provide clinicians with a new tool to better diagnose and monitor a variety of motor neuron degenerative disorders. To accelerate research in this area, I offer to share experimental data and an inventory of polyclonal antibodies specific to Big tau to the research community to enable further investigation of Big tau as a clinical biomarker.},

Cuproptosis, a newly recognized type of Cu-dependent cell death, is mechanistically distinct from apoptosis, autophagy, pyroptosis, and ferroptosis. It is characterized by abnormal Cu accumulation and aberrant interactions with key enzymes of the tricarboxylic acid (TCA) cycle, which lead to protein aggregation, loss of iron-sulfur cluster proteins, and proteotoxic stress, ultimately leading to cell death. Recent studies have revealed that Cu dyshomeostasis and cuproptosis are intricately linked to the pathological progression of several neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), Wilson's disease (WD), and Menkes disease (MD). In this review, we systematically elucidate the systemic Cu metabolism, the molecular mechanisms of cuproptosis, and its intricate interplay with different neurodegenerative disorders. We also examined the relationship between cuproptosis and other types of cell death. Finally, we discuss therapeutic strategies targeting cuproptosis and Cu dyshomeostasis to combat neurodegenerative diseases and propose potential directions for future research.},

abstract = {Amyotrophic lateral sclerosis (ALS) is an incurable, lethal neurodegenerative disease and a proteinopathy with >97 % of cases characterised by pathological accumulation of TDP-43. TDP-43 is ubiquitously expressed and its pathological accumulation has now been identified in non-neuronal cells in both the central and peripheral nervous systems. Thus, the expansion to exploring other cells and their contribution to ALS pathogenesis may be the key to finding more effective treatments. Schwann cells are the myelinating cells of the peripheral nervous system, that encase neuronal axons to propagate action potentials, maintain neuronal health, and respond to neuronal activity in the extracellular environment. Despite Schwann cells being identified to exhibit aberrant TDP-43 proteinopathy in ALS patients, their role in disease remains elusive. Here, we review the potential contributions of Schwann cells to ALS as well as the prospective benefits of harnessing Schwann cells treat the disease.},

Emerging research highlights the involvement of the gut-brain axis, immune system, and peripheral metabolic systems in modulating neuroinflammation, protein misfolding, and neuronal dysfunction by releasing cytokines, adipokines, growth factors, and other soluble factors, which in turn affect neuronal health and systemic inflammation. This review explores the complex bidirectional interactions between the brain and peripheral organs, including the gut, adipose tissue, liver, muscle, bone and immune system. Notably, the gut microbiome's role in neurodegenerative diseases through the gut-brain axis, the impact of adipose tissue in inflammation and metabolic regulation, and the muscle-brain axis with its neuroprotective myokines are also discussed. Additionally, we examine the neuro-immune axis, which mediates inflammatory responses and exacerbates neurodegeneration, and liver-brain axis that is implicated in regulating neuroinflammation and promoting disease progression. Dysregulation of inter-organ pathways contributes to the systemic manifestations of neurodegenerative diseases, offering insights into both potential biomarkers and therapeutic targets, and, in turn, promising strategies for preventing, diagnosing, and treating neurodegenerative diseases.},

abstract = {Transposable elements (TEs), once regarded as genomic "junk," are now recognized as powerful regulators of gene expression, genome stability, and innate immunity. In the context of neurodegeneration, particularly Amyotrophic Lateral Sclerosis (ALS), accumulating evidence implicates TEs as active contributors to disease pathogenesis. ALS is a fatal motor neuron disease with both sporadic and familial forms, linked to genetic, epigenetic, and environmental factors. While coding mutations explain a subset of cases, advances in long-read sequencing and epigenomic profiling have unveiled the profound influence of non-coding regions-especially retrotransposons such as LINE-1, Alu, and SVA-on ALS onset and progression. TEs may act through multiple mechanisms: generating somatic mutations, disrupting chromatin architecture, modulating transcriptional networks, and triggering sterile inflammation via innate immune pathways like cGAS-STING. Their activity is normally repressed by epigenetic regulators, including DNA methylation, histone modifications, and RNA interference pathways; however, these controls are compromised in ALS. Taken together, these insights underscore the translational potential of targeting transposable elements in ALS, both as a source of novel biomarkers for patient stratification and disease monitoring, and as therapeutic targets whose modulation may slow neurodegeneration and inflammation. This review synthesizes the current knowledge of TE biology in ALS; integrates findings across molecular, cellular, and systems levels; and explores the therapeutic potential of targeting TEs as modulators of neurodegeneration.},

abstract = {Decades ago, previous studies that used non-selective ergot derivatives suggested that blockage of the α1A-adrenergic receptor mildly increased cognition through increased blood flow to the brain due to vasodilation and, thus, could be used as a treatment for dementia. However, further studies indicated that nicergoline was non-specific and hit many different targets. Today, a similar scenario is developing with the use of non-selective α1-AR antagonists of the quinazoline class, referred to as "osins", as potential treatments for COVID-19/SARS, post-traumatic stress disorder, cancer, and neurodegenerative disorders, such as Parkinson's, Alzheimer's, and amyotrophic lateral sclerosis. While there is extensive evidence of neuroprotection from many clinical trials, the mechanism of action of quinazolines is often not α1-AR-mediated but keyed to its glycolysis-enhancing effects through activation of the enzyme phosphoglycerate kinase 1 (PGK1). These studies have incorrectly labeled the α1A-adrenergic receptor as an "old target" to treat Alzheimer's and other neurocognitive diseases, hampering drug development. This review will summarize these and other studies to indicate that activation, not blockage, of norepinephrine's actions, through α1A-AR, mediates cognitive, memory, and neuroprotective functions that may reverse the progression of neurocognitive diseases.},

abstract = {Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder involving the progressive degeneration of upper and lower motor neurons. While oxidative stress, RNA-binding protein (RBP) pathology, mitochondrial dysfunction, and glial-neuronal dysregulation is involved in ALS pathogenesis, current therapies provide limited benefit, underscoring the need for multi-target disease-modifying strategies. Nuclear factor erythroid 2-related factor 2 (Nrf2), classically regarded as a master regulator of redox homeostasis, has recently emerged as a central integrator of cellular stress responses relevant to ALS. Beyond its canonical antioxidant function, Nrf2 regulates critical pathways involved in mitochondrial quality control, proteostasis, nucleocytoplasmic transport, RNA surveillance, and glial reactivity. Experimental models demonstrate that astrocyte-specific Nrf2 activation enhances glutathione metabolism, suppresses neuroinflammation, promotes stress granule disassembly, and reduces RBP aggregation. In C9orf72-linked ALS, Nrf2 activation mitigates dipeptide repeat protein toxicity and restores RNA processing fidelity via modulation of nonsense-mediated decay and R-loop resolution. Recent advances in Nrf2-targeted interventions including Keap1-Nrf2 protein-protein interaction inhibitors, dual Nrf2/HSF1 activators, and cell-type-selective Adeno-associated virus 9 (AAV9) vectors show promise in preclinical ALS models. These multimodal approaches highlight Nrf2's therapeutic versatility and potential to address the upstream convergence points of ALS pathogenesis. Taken together, positioning Nrf2 as a systems-level regulator offers a novel framework for developing precision-based therapies in ALS. Integrating Nrf2 activation with RNA- and glia-directed strategies may enable comprehensive modulation of disease progression at its molecular roots.},

RA is also known to have non-canonical activities mediated, primarily, by cellular retinoic acid-binding protein 1 (CRABP1) which forms protein complexes named "CRABP1 signalosomes" to regulate cytosolic signaling independent of RARs/RXRs. This review focuses on therapeutic applications in neurodegeneration by targeting CRABP1 signalosomes including CRABP1-MAPK, CRABP1-CaMKII, CRABP1-eIF2α, and others recently identified from our proteomic studies. The mouse Crabp1 gene is regulated by various epigenetic factors and is important for the health of multiple cell types including motor neurons (MNs). In humans, CRABP1 gene expression is reduced in ALS- and SMA-patient MNs. RA is a therapeutic agent for leukemias and dermatological disorders and is being investigated for managing neurodegenerative diseases, but its therapeutic effects are accompanied by RAR-mediated toxic effects. We have uncovered a novel class of synthetic retinoids that bind CRABP1 without acting on RARs, circumventing RAR-mediated toxic effects. These first-generation CRABP1-selective compounds C3, C4, and C32 target CRABP1-MAPK and/or CRABP1-CaMKII signalosomes. This knowledge, together with emerging structural information, sheds lights on the strategies in designing next-generation CRABP1-signalosome-selective retinoids for the management of neurodegenerative diseases.},

There is a growing body of evidence suggesting that the collapse of proteostasis, the failure of protein homeostasis, is an important contributor to neurotoxicity. In this review, we suggest that this collapse is exacerbated by ionic dysregulation, an important but under-addressed cause of neurodegeneration. Importantly, breakdowns in chloride, bicarbonate, sodium, and calcium homeostasis alter fundamental aspects of cellular physiology, including important aspects of TDP-43 phase separation and tau hyperphosphorylation and aggregation. We suggest that the relationship of proteostasis failure and ionic dysregulation is a bidirectional feedback loop that accelerates the progression of neurodegeneration. Some therapeutic strategies aimed at correcting these mechanisms-including small-molecule chaperone inducers, autophagy inducers, and ion-channel modulators-might hold the potential for disease modification. In this review, we document the complex intersections of proteostasis failure and ionic dysregulation in TDP-43 and tauopathies and provide new ideas for therapies and future studies.},

The aim of this scoping review is to evaluate oral health status in ALS patients focusing on the importance of dental care in improving patient's quality of life. Methods: A comprehensive literature search was conducted on PubMed, Scopus, Web of Science, and Embase databases until June 2025 using a combination of keywords and MeSH terms related to ALS and oral health. Studies were screened and selected based on inclusion and exclusion criteria, focusing on human clinical data reporting oral health outcomes in ALS. Results: Eight studies met the inclusion criteria. The findings showed a high prevalence of oral complications in bulbar-onset ALS patients. Common issues included reduced tongue mobility, poor oral hygiene, sialorrhea, and decreased masticatory function were evaluated. Conclusions: Oral health impairment in ALS patients frequently contributes to systemic risks and reduced quality of life. A dental expert may play an important role in multidisciplinary care teams in terms of early diagnosis and conservative treatment of oral diseases ranging from periodontal disease to temporomandibular disorders (TMD). Personalized oral hygiene strategies and adjunctive therapies may serve as key elements in maintaining overall health and patient comfort in ALS. Therefore, the objective of the following review was to evaluate oral health complication in patients with ALS, highlighting the impact of oral care on patients' quality of life.},

Of recent interest, a series of studies have been targeting the role of non-coding RNAs, particularly miRNAs and lncRNAs, in regulating gene expression and influencing cellular pathways that may play a critical role in the pathogenesis of these diseases. miRNAs regulate many biological processes by degrading or repressing the translation of target mRNAs, whereas lncRNAs act as scaffolds, sponges, and guides to control gene expression and cellular activities. Both miRNAs and lncRNAs participate in neurodegenerative mechanisms such as protein aggregation, inflammation, oxidative stress, and neuroinflammation. While targeting miRNAs and lncRNAs holds promise for potential therapeutic benefits, problems persist with their efficient delivery, specificity, and off-target effects. New techniques like viral vectors, lipid nanoparticles, and CRISPR-based gene editing will further enhance the development of therapies based on miRNA and lncRNA. Moreover, their interaction with regulatory networks may present new avenues toward understanding disease mechanisms and guiding therapeutic design. This review covers the role of miRNAs and lncRNAs in neurodegenerative disorders, their therapeutic potential, challenges, and future directions in ncRNA-based treatment approaches.},

abstract = {OBJECTIVES: This review aimed to synthesise current evidence on the effects of gastrostomy in Parkinson's disease (PD) and parkinsonism, Multiple Sclerosis (MS) and Huntington's disease (HD).

PURPOSE: Evidence regarding the risks and benefits of gastrostomy insertion and use in progressive neurological diseases, excluding Motor Neurone Disease (MND), is lacking, causing gastrostomy decision-making discussions to arise as a matter of debate in practice.

METHODS: Three databases (Web of Science, Ovid Medline and Embase) were searched for research on the impacts of gastrostomy, including survival, complication rates, nutrition changes, in adults with progressive neurological diseases, excluding MND. Quality was assessed using the Academy of Nutrition and Dietetics Quality Criteria Checklist: Primary Research, and a narrative synthesis was conducted.

RESULTS: Twelve (n = 12) studies were eligible for inclusion, with either retrospective cohort (n = 12) or cross-sectional (n = 1) design, examining the effects of percutaneous endoscopic gastrostomy (PEG) (n = 8), radiologically inserted gastrostomy (RIG) (n = 1) or gastrostomy not further defined (n = 4) in adults with PD (n = 6), parkinsonism (n = 3), MS (n = 3), or HD (n = 3). There was variability in outcomes and comparators with inconclusive results. Quality was assessed as positive (n = 3) or neutral (n = 9). Gastrostomy appears to be associated with increased care needs in the population of interest.

CONCLUSIONS: Gastrostomy insertion and use in this cohort is poorly investigated. High-quality prospective studies, especially with well-defined nutrition-related outcome measures, and robust statistical analyses are needed to determine the potential benefits of gastrostomy in this population.

A 65-year-old man with sporadic ALS (sALS) carrying a NEK1 c.2413dup (p.Thr805Asnfs*7) mutation was studied. Clinical and genetic data were evaluated using Mutation Taster and ACMG guidelines. A literature review was conducted in PubMed and CNKI to identify ALS cases with NEK1 mutations. Whole-exome sequencing identified a NEK1 mutation, c.2413dup (p.Thr805Asnfs*7),which is predicted to lead to a truncated protein. A literature review found 19 articles covering 89 mutation sites. Among the recorded cases, sex was reported for 79 cases (47 male,32 female), and age of onset was available for 80 cases, with an average of 56.94 ± 11.88 years. Onset type data were available for 77 cases, of which 49.35% (38/77) had lower motor neuron onset,41.56% (32/77) had upper motor neuron onset, and 9.09% (7/77) had both. Among those with lower motor neuron onset (n = 38),28.95% (11/38) had bulbar onset, and 2.63% (1/38) had respiratory onset. The c.2413dup (p.Thr805Asnfs*7) frameshift mutation in the NEK1 gene is likely pathogenic and may contribute to the onset of ALS. ALS associated with NEK1 mutations appears to be more common in men than women and typically affects individuals in late middle age.},

Results revealed that of multiple tentative ASO treatments, for multiple specific gene mutations, only one, Tofersen, was approved for the wider population. The main cause of failure was an inability to meet efficacy endpoints, resulting in the discontinuation of the product. Tofersen is able to treat mutations in the SOD1 gene, but not any others. While initially discouraging, the production of ASOs is a relatively new and advanced process, and slow progress is expected. However, there remains the problem of identifying and treating the much more prevalent sporadic ALS, which is much more common compared to familial ALS.},

abstract = {BACKGROUND: Reliable biomarkers for amyotrophic lateral sclerosis (ALS) are urgently needed due to diagnostic and prognostic challenges. This systematic review and meta-analysis aimed to synthesize recent evidence on the utility of blood and cerebrospinal fluid (CSF) biomarkers for ALS.

METHODS: We systematically reviewed studies published from January 1, 2019 to March 25, 2025, that evaluated blood or CSF biomarkers for ALS. Eligible studies reported diagnostic performance, group-level biomarker values, hazard ratios (HRs) for survival, or correlations with functional rating scales or disease progression rates. Study quality was assessed using the QUADAS-2 and QUIPS frameworks. Random-effects models were employed to pool summary receiver operating characteristic (SROC) curves, HRs, standardized mean differences, and correlation coefficients.

RESULTS: We included 47 studies in the SROC analysis and 27 in the HR analysis, covering 9078 participants (5556 ALS and 3522 controls). Neurofilament light chain (NfL) consistently demonstrated the highest diagnostic accuracy (sensitivity/specificity: 0.81-0.87 vs. ALS mimics) and high prognostic value (pooled HRs: 2.8-4.3) in both blood and CSF. CSF chitinases and the p-tau/t-tau ratio showed moderate utility. Other biomarkers, including interleukins, had limited clinical relevance. Most studies showed moderate to high risk of bias, with methodological heterogeneity and limited transparency.

CONCLUSIONS: NfL is the most validated biomarker for ALS diagnosis and prognosis, in both blood and CSF. However, its limited accuracy when used alone carries a considerable risk of misclassification. Future studies should adopt prevalence-specific strategies and integrate biomarkers within multimodal frameworks to enhance diagnostic and prognostic precision.},

Proteins are used at the molecular level to categorize neurodegenerative disorders, emphasizing the importance of protein-processing mechanisms in their development. Natural herbal phytoconstituents, such as icariin, have addressed these neurological complications. Icariin, the principal compound in Epimedium, has been studied for its antineuroinflammatory, anti-oxidative, and antiapoptotic properties. Recent scientific investigations have shown that icariin exhibits promising therapeutic and preventive properties for mental and neurodegenerative disorders. In preclinical, icariin has been shown to inhibit amyloid development and reduce the expression of APP and BACE-1. Previous preclinical studies have demonstrated that icariin can regulate proinflammatory responses in neurological conditions like Parkinson's disease, depression, cerebral ischemia, ALS, and multiple sclerosis. Studies have shown that icariin possesses neuroprotective properties by modulating signaling pathways and crossing the blood-brain barrier, suggesting its potential to address various neurocomplications. This review aims to establish a foundation for future clinical investigations by examining the existing literature on icariin and exploring its potential therapeutic implications in treating neurodegenerative disorders and neuropsychiatric conditions. Future research may address numerous concerns and yield captivating findings with far-reaching implications for various aspects of icariin.},

In neurons, the ER extends into axons, where it plays a pivotal role in maintaining neuronal polarity. The unique structural and dynamic adaptations of the axonal ER enable it to meet the specialized demands of neurons, ranging from compartmentalized physiological regulation to long-distance intracellular communication. Recent studies have shown that axonal ER supports the regulation of organelle remodeling and trafficking in a spatiotemporal manner, processes that become compromised in aged neurons. Moreover, disruptions in the structure and dynamics of the axonal ER have increasingly become associated with neurodegenerative diseases, including hereditary spastic paraplegia, amyotrophic lateral sclerosis, and peripheral neuropathies. This review synthesizes current knowledge of axonal ER biology, highlighting its structural and dynamic characteristics, its impact on organelle arrangement and distribution, and its pathological implications in neurodegeneration. By consolidating recent advances, this review outlines emerging questions and future directions in axonal ER research, a field gaining recognition for its contribution to neuronal dysfunction and neurodegenerative pathomechanisms.},

Over the years, several protocols have been developed to standardize the behavior of healthcare professionals called upon to deal with these emergencies. Advanced Cardiac Life Support (ACLS) algorithms enable healthcare professionals to effectively manage cardiac arrest and achieve better patient outcomes, particularly at the time of discharge.

METHODS: We conducted a narrative review. Three databases (PubMed, Embase, Cochrane) were searched for relevant articles. The articles were screened and analyzed in accordance with the PRISMA guidelines.

RESULTS: A total of 1252 articles were initially identified. After screening, 11 papers were included in the review. From the selected studies, it has emerged that ACLS training had several positive effects, including an overall decrease in mortality rates. Adherence to ACLS protocols throughout an event is associated with increased Return of Spontaneous Circulation (ROSC) in the setting of In-Hospital Cardiac Arrest (IHCA). Advanced Life Support (ALS) response interval in out-of-hospital cardiac arrest was associated with decreased survival and a favorable neurological outcome. ALS response ≤ 10 min was associated with improved survival and favorable neurological outcomes.

CONCLUSIONS: This review underscores the importance of adherence to ALS/ACLS guidelines in the resuscitation of patients who suffer in-hospital and out-of-hospital cardiac arrest.},

abstract = {INTRODUCTION: This report presents the first case of a patient with high cervical spinal cord injury who underwent successful laparoscopic implantation of a diaphragm pacing system in Taiwan. It also compares the pros and cons of laparoscopic and thoracoscopic implantation and discusses postoperative care.

BACKGROUND: The diaphragm pacing system (DPS) represents a substantial advancement in respiratory support technology, particularly for patients with chronic respiratory insufficiency. It electrically stimulates the phrenic nerve, which in turn activates the diaphragm-the primary muscle involved in respiration [1]. This stimulation mimics the natural neural impulses that drive diaphragmatic contractions, thereby promoting inhalation and a more efficient lung ventilation. The DPS typically consists of implanted electrodes, an external pulse generator, and connecting leads [2]. It is mainly used in patients with high spinal cord injuries, amyotrophic lateral sclerosis, and central hypoventilation syndrome. These conditions often result in compromised neural control of the diaphragm, leading to severe respiratory insufficiency. By restoring diaphragm function, DPS can enhance the patients' quality of life, reduce dependence on mechanical ventilators, and lower the risk of ventilator-associated complications [3]. Despite its benefits, DPS is not without challenges. Patient selection and the surgical approach are critical to perform successful DPS implantation for the restoration of diaphragm function [4]. This report presents the first case of a patient with cervical spine injury who underwent successful laparoscopic implantation of DPS in Taiwan. Furthermore, it discusses postoperative ICU care and reviews the pros and cons of different surgical approaches to performing DPS implantation.},

Primary cilia are solitary microtubule-based organelles critical for signal transduction and have recently been implicated in ALS pathogenesis. In this review, we provide a basic overview of the structure, dynamics, and functions of primary cilia, particularly in the brain. We highlight accumulating evidence from ALS models showing altered ciliary structure and function and explore how mutations in ALS-associated genes such as NEK1, C21orf2, and C9orf72 disrupt ciliogenesis and ciliary signaling. Moreover, we examine the interplays between primary cilia dysfunction and known ALS-related mechanisms, including loss of proteostasis, abnormal RNA metabolism, microtubule dysfunction, neuroinflammation, and mitochondrial dysfunction. Collectively, the evidence suggests a bidirectional relationship in which ciliary impairment and ALS pathomechanisms reinforce one another in a vicious cycle. We further discuss emerging therapeutic strategies targeting ciliary function, as well as the potential for primary cilia as novel clinical applications. Our review highlights primary cilia as a previously underappreciated yet potentially important component of ALS biology, offering novel insights into disease mechanisms and future therapeutic development.},

However, recent translational researches in collaboration of basic studies and human pathology indicate that FTLD arises from more complex molecular mechanisms than dyshomeostasis of single molecules. Additionally, accumulation of clinicopathological evidences from various countries, genetic backgrounds or clinical specialties (e.g. neurology and psychiatry), suggests diverse phenotypes of FTLD, which are indicative of future paradigm-shift in the concept of FTLD.

Lipocalin-2 (LCN2) is a secreted protein involved in lipid transport that plays a key role in inflammatory responses and the regulation of iron homeostasis. The role of LCN2 in ALS has attracted increasing attention, as significantly elevated LCN2 expression has been observed in the blood and postmortem tissues of ALS patients. Functionally, LCN2 participates in neuroinflammation, iron dysregulation, cell death, and peripheral immune immunity, proposing a central-peripheral linkage hypothesis mediated by LCN2. Clinically, LCN2 shows promise as both a biomarker and a therapeutic target, with multiple strategies demonstrating potential to mitigate ALS pathology. Moving forward, it is essential to integrate multi-omics to deeply decipher LCN2-mediated molecular networks, advance patient stratification, and accelerate its clinical translation.},

They play a key physiological role in maintaining the structural integrity and plasticity of axons and in ensuring the axonal transport function. Under pathological conditions, NFs detach from axons and undergo abnormal aggregation, causing axonal transport dysfunction. In addition, some components of the detached NFs leak into the peripheral circulation system. In patients with amyotrophic lateral sclerosis (ALS), the concentration of NFs is significantly elevated in the cerebrospinal fluid and blood, and the changes in NFs concentration is significantly positively correlated with the disease progression of ALS, suggesting the potential of NFs being used as early diagnostic biomarkers for ALS. In this review, we explored the relationship between NFs structure, assembly, and physiological function, focusing on the molecular mechanisms and clinical manifestations of ALS caused by abnormal assembly of NFs. We comprehensively summarized recent advances in the application of NFs as a new humoral biomarkers for early diagnosis and therapeutic monitoring of ALS. Key challenges in biomarker development-including undefined pathological neurofilament light chain (NFL) fragments, limited antibody availability, and poor assay reproducibility-are discussed. Strategies, including ultrasensitive detection technologies such as single molecule array (Simoa), antibody optimization based on pathological fragment identification, and multi-omics biomarker panels, should be integrated. These approaches may lead to breakthroughs, pave the way for precision-based ALS diagnosis, provide theoretical support for promoting its clinical translation and application, and offer ideas for future research.},

However, we reanalyzed their subgroup analyses to evaluate the methodological implications of statistical model selection (fixed-effect vs. random-effect models) on result reliability. In dose-stratified analyses, Cao et al. applied fixed-effect models to low-dose (I[2] = 0%) and high-dose (I[2] = 80%) MSC subgroups. Upon reanalysis using random-effect models, the high-dose group showed no statistically significant differences in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total scores compared to the control group at 6 months [MD = 8.75; 95% CI (-2.10, 19.61); P = 0.11] or 12 months [MD = 12.68; 95% CI (-4.96, 30.32); P = 0.16], contrasting with Cao et al.'s original findings. The low-dose subgroup, with no heterogeneity, yielded identical results across both models. Similarly, in cell-source stratification (adipose-derived MSCs [ADMSCs] vs. bone marrow-derived MSCs [BM-MSCs]), reanalysis of ADMSCs using random-effect models demonstrated significant 6-month WOMAC improvement [MD = 9.32; 95% CI (3.73, 14.92); P = 0.001] but non-significant 12-month differences [MD = 12.90; 95% CI (-1.76, 27.55); P = 0.08], diverging from Cao et al.'s conclusions. BM-MSCs results remained consistent due to negligible heterogeneity (I[2] = 0%). These findings underscore that fixed-effect models artificially narrow confidence intervals in heterogeneous populations, overestimating clinical significance. Our results align with Cochrane guidelines, emphasizing that random-effect models better accommodate inter-study diversity, yielding conservative and clinically generalizable estimates. This critique reinforces the necessity of transparent statistical model selection in meta-analyses, particularly when subgroup heterogeneity may influence therapeutic interpretations.},

Disruptions in this axis, driven by gut dysbiosis, have been implicated in the pathogenesis of a wide range of neurodegenerative and neuropsychiatric disorders. This review synthesizes current evidence linking microbiota alterations to Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), and stroke-including post-stroke cognitive impairment (PSCI), as well as major depressive disorder (MDD), bipolar disorder (BD), anxiety disorders, post-traumatic stress disorder (PTSD), and chronic fatigue syndrome (CFS). Common findings include reduced microbial diversity, depletion of short-chain fatty acid (SCFA)-producing genera, and enrichment of pro-inflammatory taxa. These changes contribute to neuroinflammation, blood-brain barrier (BBB) dysfunction, microglial activation, and neurotransmitter imbalances. The review further explores the neurotoxic effects of external factors such as radiation and xenobiotics on the MGBA. Despite disorder-specific variations, shared microbial and immunological mechanisms emerge across the spectrum of conditions. Importantly, we present current and emerging strategies aimed at restoring gut-brain communication, including dietary interventions such as fiber-rich and Mediterranean diets, SCFA supplementation, probiotics, and fecal microbiota transplantation (FMT). These approaches show promise in alleviating cognitive and emotional symptoms, modulating immune responses, and potentially slowing disease progression. By integrating mechanistic insights with therapeutic perspectives, this review underscores the gut microbiota as a modifiable factor in neuropsychiatric and neurodegenerative disease. Targeting the MGBA offers a novel, translational approach to intervention that may ultimately contribute to healthier brain aging and improved outcomes across the lifespan.},

Special care services; e.g. Advanced Life Support, critical care interventions (intubation; vasopressor therapy) and point of care diagnostics (ultrasound) may be provided in disaster-settings, although actual use of services is dependent on logistical, operational and contextual issues. This systematic review identifies an important gap to understand the effectiveness, feasibility and barriers to, special care services.The overall aim of this systematic review is to synthesise global evidence on the evidence-based practices and improve disaster response.

METHODS: This systematic review utilized PubMed, Scopus, Web of Science, Embase, and grey literature from the time of inception of the different databases to January 2025, from which a total of 4465 records were identified. After a thorough, organized review of the identified records based on our exclusion criteria and inclusion criteria, a total of 31 articles were retained. The systematic review followed PRISMA 2020, and searched for studies on special care services in a pre-hospital disaster setting, and included primary research and review articles that described advanced interventions, and which had no time restrictions on date of publication. Articles that were waived from the cost of in-app purchasing were excluded due to limited resources and could limit the studies that were included. Quality assessment using STROBE, SANRA and checklists, along with the categories of findings using a thematic content analysis based on the dimensions of prehospital care.

RESULTS: Thematic analysis revealed six broad themes: Patient Care and Clinical Management, Operational Efficiency and Logistics, Personnel and Training, Technology and Equipment, System Coordination and Preparedness, and Ethical and Contextual Considerations. Advanced functions like REBOA, ultrasound and AI-related diagnostics improved survival and neurological outcomes, However, they were restricted due to limited resources, lack of training, and lack of coordination, particularly in low resource contexts.

CONCLUSIONS: The reviewed literature demonstrated that critical-care services such as Advanced Life Support (ALS), intubation, and ultrasound resulted in improved morbidity and mortality outcomes in disaster settings but were limited due to resource constraints, lack of training and inadequate coordination all the more pertinent to low-resource settings.

Advances in understanding ALS pathophysiology, including the role of RNA metabolism, mitochondrial dysfunction, and glutamate toxicity, have paved the way for new research directions. While Riluzole offers limited survival benefits, there is no cure, and treatment remains mostly supportive. This article summarizes the current understanding of ALS in terms of its pathophysiology, epidemiology, risk factors, clinical presentation, and treatment strategies.},

abstract = {Neurodegenerative disorders are marked by the gradual degeneration of neurons and deterioration of cognitive function. One key underlying factor in these diseases is neuroinflammation. An essential component of this process is microglia, which are the innate immune cells that maintain homeostasis in the brain. A common outcome of microglial dysregulation in neurodegenerative diseases is chronic neuroinflammation, which exacerbates neuronal damage and impairs synaptic function. This review focuses on the dual roles that disease-associated microglia (DAMs) play in neural inflammation and neuroprotection as well as their distinct transcriptional profile in neurodegenerative diseases. DAMs engage in phagocytosis to remove debris, in addition to releasing cytokines that promote inflammation. To create an effective medicine, it is imperative to comprehend these dual functions. The roles of DAMs in Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS) are discussed, along with the mechanisms (such as the TREM2-APOE pathway) causing their activation. This review attempts to highlight the important aspects that could direct future investigations and treatment development by clarifying the interactions between DAMs and neurodegenerative diseases.},

abstract = {The distinction between normal brain aging and neurodegeneration has traditionally been viewed as a binary classification, yet emerging evidence reveals a complex continuum of shared genetic mechanisms underlying both processes. This review synthesises current understanding of conserved molecular pathways that contribute to age-related neural decline across the spectrum from healthy aging to pathological neurodegeneration. We examine how fundamental cellular processes including protein quality control, mitochondrial dysfunction, inflammation, and synaptic maintenance are genetically regulated and become progressively dysregulated during aging. Key genetic pathways, such as insulin/IGF signalling, autophagy-lysosomal networks, and stress response mechanisms demonstrate remarkable conservation from model organisms to humans, suggesting evolutionary constraints on neural aging processes. The review highlights how genetic variants in these pathways can determine individual trajectories along the aging-neurodegeneration continuum, influencing susceptibility to diseases like Alzheimer's, Parkinson's, and ALS. We discuss evidence from comparative studies in C. elegans, Drosophila, rodents, and human populations that illuminate shared vulnerability genes and protective factors. Understanding these convergent mechanisms offers unprecedented opportunities for therapeutic intervention, as strategies targeting fundamental aging processes may simultaneously address multiple neurodegenerative conditions. This integrated perspective challenges traditional disease-centric approaches and supports the development of unified therapeutic strategies for promoting healthy brain aging while preventing neurodegeneration.},

Autophagosome-lysosome fusion represents the final critical step in macroautophagy with a tightly regulated process mediated by a complex molecular machinery of tethering vesicles for degradation. Since the first reports of human autophagy disorders, the scientific and clinical focus condensed on severe phenotypes with biallelic-truncating genotypes as monogenic models of near-complete autophagy perturbation. Recent reports suggest a much wider disease spectrum with defective autophagy, ranging from neurodevelopmental disorders to neurodegenerative phenotypes with later manifestation due to "milder" genotypes, including Alzheimer's disease (AD), Parkinson's disease (PD), and Amyotrophic Lateral Sclerosis-Frontotemporal Dementia (ALS-FTD). In addition, recent evidence identified molecular connections between physiological autophagy regulation during normal aging and pathophysiological hallmarks of aging-related disorders. These translational observations led to a more comprehensive understanding of autophagy at health and disease, in particular: 1) genetic location and allelism of pathogenic variants ("genomic space"); 2) protein-protein interaction in functional protein complexes ("proteomic space"); 3) metabolic autophagic flux with positive and negative regulators ("metabolomic space"); 4) age-related phenotypic progression over time. Here, we review the autophagosome-lysosome fusion machinery as a key structure both on the molecular level and with regards to the pathogenesis of the autophagy-related disease spectrum. We highlight the clinicopathological signature of disorders in the autophagosome-lysosome fusion machinery, in particular features warranting awareness from clinicians and geneticists to inform adequate diagnosis, surveillance, and patient guidance.},

abstract = {In the recent years, the accelerating global demographic shift toward population aging has been accompanied by a marked increase in the prevalence of neurodegenerative disorders, notably Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and multiple sclerosis. Among emerging approaches, dietary interventions targeting the gut-brain axis have garnered considerable attention, owing to their potential to modulate key pathogenic pathways underlying neurodegenerative processes. This review synthesizes current concepts in precision nutrition and elucidates neurohumoral, immune, and metabolic regulatory mechanisms mediated by the gut microbiota, including the roles of the vagus nerve, cytokines, short-chain fatty acids, vitamins, polyphenols, and microbial metabolites. Emerging evidence underscores that dysbiotic alterations contribute to compromised barrier integrity, the initiation and perpetuation of neuroinflammatory responses, pathological protein aggregations, and the progressive course of neurodegenerative diseases. Collectively, these insights highlight the gut microbiota as a pivotal target for the development of precision-based dietary strategies in the prevention and mitigation of neurodegenerative disorders. Particular attention is devoted to key bioactive components such as prebiotics, probiotics, psychobiotics, dietary fiber, omega-3 fatty acids, and polyphenols that critically participate in regulating the gut-brain axis. Contemporary evidence on the contribution of the gut microbiota to the pathogenesis of Alzheimer's disease, Parkinson's disease, and multiple sclerosis is systematically summarized. The review further discusses the prospects of applying nutrigenomics, chrononutrition, and metagenomic analysis to the development of personalized dietary strategies. The presented findings underscore the potential of integrating precision nutrition with targeted modulation of the gut-brain axis as a multifaceted approach to reducing the risk of neurodegenerative diseases and preserving cognitive health.},

abstract = {Neuroaxonal damage underlies permanent disability in various neurological conditions, both neuroautoimmune and neurodegenerative. It is crucial to accurately quantify and monitor axonal injury using biomarkers to evaluate disease progression and treatment effectiveness and offer prognostic insights. Neurofilaments (NFs), and especially neurofilament light chain (NfL), show promise for this purpose, as their levels increase with neuroaxonal damage in both cerebrospinal fluid and blood, independent of specific causal pathways. Recent advances in ultrasensitive immunoassays enable the reliable detection of NFs in blood, transforming them from research tools into clinically applicable measures. In multiple sclerosis (MS), serum NfL correlates with disease activity, treatment response, and long-term disability, and may complement MRI in monitoring subclinical progression. In MS, NfL is primarily emerging as a marker of disease activity and treatment response; in amyotrophic lateral sclerosis (ALS), it has progressed further, being integrated into clinical trials as a pharmacodynamic endpoint and considered by regulatory agencies as a drug development tool. Additionally, NFs are increasingly being investigated in Alzheimer's disease, frontotemporal dementia, and other neurodegenerative disorders, though their disease specificity is limited. Ongoing challenges include older and novel assay harmonization, normative range interpretation, biological and analytical variability, and integration with other molecular and imaging biomarkers. This critical narrative review synthesizes the existing literature on NFs as diagnostic, prognostic, predictive, and pharmacodynamic biomarkers and discusses their role in therapeutic development and precision medicine in neuroautoimmune and neurodegenerative diseases.},

In multiple sclerosis (MS), mAbs against CD20, CD52, and α4-integrins offer disease-modifying efficacy by altering immune responses, depleting B cells, or blocking leukocyte migration into the central nervous system (CNS). Similarly, novel agents under investigation, such as frexalimab and foralumab, modulate T and B cell interactions and regulatory immunity. In neuromyelitis optica spectrum disorder (NMOSD), mAbs targeting IL-6, the complement cascade, and B cell lineage have demonstrated significant clinical benefit in preventing relapses and disability. In Alzheimer's disease (AD), several anti-amyloid mAbs have gained regulatory approval. Anti-tau and anti-α-synuclein antibodies, though promising, have shown limited efficacy to date in AD and parkinson's disease (PD), respectively. The evolving armamentarium of mAbs reflects a paradigm shift toward personalized neuroimmunology and neurodegeneration-targeted treatments, based on ongoing clarification of molecular and neuroinflammatory mechanisms.

abstract = {BACKGROUND: Speech loss is recognised as one of the most devastating outcomes for individuals with ALS, yet active speech intervention is rarely targeted in this population. Clinicians face significant challenges in managing dysarthria associated with ALS due to the rapidly progressive nature of the disease, historical concerns around intensive exercise accelerating decline, and an absence of direction on restorative and compensatory intervention strategies in current clinical care guidelines. This review evaluates the scope and quality of evidence for speech treatments in ALS to identify knowledge gaps and establish research priorities to guide clinical care.

METHODS: Studies were retrieved from six electronic databases (PubMed, CINAHL, Embase, Cochrane library, Web of Science, and PsycINFO).

RESULTS: Four studies met inclusion criteria. Treatment approaches included: music-based speech therapy; multisubsystem speech rehabilitation program, tongue strengthening and articulation training; and Lee Silverman Voice Treatment-LOUD[®] combined with additional voice and articulation therapy. Sample sizes were small, with all studies demonstrating notable methodological weaknesses. The limited evidence base, marked by conflicting results and methodological flaws, prevents any reliable conclusions about treatment effectiveness.

CONCLUSIONS: Despite the prevalence and impact of dysarthria in this population, evidence for speech treatment remains sparse, of generally low quality, and provides limited guidance for clinical practice. The changing perspective on exercise in ALS warrants rigorous investigation of tailored dysarthria interventions for this population that are minimally fatiguing and enhance speech by making use of residual physiologic support.},

The assumption that spinal cord and brain neurovascular systems are built and function in the same way has limited progress. Here, we challenge this view by examining specific properties underlying spinal cord vascular development, physiology, and pathology. We highlight unique angioarchitecture and homeostatic mechanisms, and discuss how neurovascular disruption contributes to spinal disorders and regenerative failure after injury. Identifying critical knowledge gaps, we aim to stimulate new research in spinal cord neurovascular biology, redefining its importance for health and disease.},

abstract = {Voltage-gated ion channels (VGICs) are critical regulators of membrane potential, cellular excitability, and calcium signaling in both excitable and nonexcitable tissues and constitute important drug targets for neurological, cardiovascular, and immunological diseases. This review describes recent progress in the pharmacology of voltage-gated Na[+], voltage-gated Ca[2+], and voltage-gated K[+] channels, highlighting clinical-stage compounds, emerging therapeutic modalities, and new strategies in VGIC drug discovery, emphasizing the increasingly central role of protein structures and artificial intelligence. Several compounds targeting VGICs have progressed to clinical trials for epilepsy, atrial fibrillation, psoriasis, and difficult-to-treat disorders, such as chronic pain, schizophrenia, major depression, and amyotrophic lateral sclerosis. The therapeutic landscape for VGIC-related disorders is expanding beyond traditional small molecules and antisense oligonucleotides and gene therapies targeting VGICs at the mRNA or gene level are currently in both early and late clinical trial stages for Dravet syndrome and developmental epileptic encephalopathy. The progression of such varied modalities suggests that the extensive efforts dedicated to elucidating VGIC biophysics and structure, coupled with rigorous target validation, are beginning to translate into therapeutic advancements. Furthermore, we discuss emerging discovery strategies, including the growing impact of VGIC structures, computational structural modeling, virtual screening of focused and ultralarge libraries, and artificial intelligence-driven redesign and de novo design of biologics. Although these approaches are poised to substantially accelerate the early stages of ion channel drug discovery, the clinical stages will continue to require careful selection of indications and thoughtful clinical trial design to fully realize the long-held potential of VGICs as drug targets. SIGNIFICANCE STATEMENT: Drug development for voltage-gated ion channels is widely considered to be challenging. This article reviews recent advances in the pharmacology of voltage-gated Na[+], voltage-gated Ca[2+], and voltage-gated K[+] channels by examining compounds currently in clinical trials, including emerging new therapeutic approaches such as antisense oligonucleotides and gene therapy. We then discuss noteworthy recent developments, including the increasing availability and impact of ion channel structures, structural modeling, virtual screening, and artificial intelligence-assisted protein design, which are likely to accelerate the early stages of ion channel drug discovery. Success of the later stages will continue to rely on rigorous target validation, and proper choices of clinical candidates and clinical trial design.},

First characterized in the brain, they influence a wide range of processes in the spinal cord, maintaining neuronal homeostasis, shaping both synaptic and intrinsic plasticity, and modulating glial responses. When dysregulated, calpains contribute to the pathophysiology of traumatic and neurodegenerative spinal cord disorders, as well as to their associated motor and sensory complications, including spasticity and neuropathic pain. A recurring feature of these conditions is calpain-mediated proteolysis of ion channels, transporters, and cytoskeletal proteins, which promotes disinhibition and neuronal hyperexcitability. The resultant protein fragments are examined as prospective biomarkers for damage and disease progression. Meanwhile, promising strategies for neuroprotection and functional recovery in the clinic emerge as a result of innovative pharmacological and genetic approaches to modulate calpain activity. In this review, we present the current state of knowledge regarding the functions and regulation of calpains in the spinal cord and assess their translational potential as both therapeutic targets and effectors in spinal cord disorders.},

Here we assess ISRIB, a molecule that attenuates the integrated stress response (ISR). The ISR is an intracellular signaling network through which cells normally respond to stress, but in ALS it appears to be overactive, leading to the formation of "stress granules" which some but not all investigators believe can triggerapoptotic cell death. ISRIB can attenuate the formation of these stress granules while still allowing parts of protein synthesis to continue. Pre-clinical data demonstrate that ISRIB is beneficial in cell models of ALS. A small number of patients taking ISRIB in Spain report symptomatic improvements with little or no side effects, though we have not been able to independently verify these benefits. There are no clinical trials evaluating ISRIB in any condition and questions about its solubility and bioavailability have arisen. Currently, we do not have enough evidence to endorse the use of ISRIB for treating ALS. We support further research in disease models and clinical trials to study pharmacokinetics, safety and efficacy.},

Glial cells, once considered passive supporters, are now recognized as central drivers of these processes, offering both pathogenic triggers and therapeutic opportunities. Yet, despite compelling preclinical evidence, the translation of glial-targeted therapies into clinical success has been limited. This review provides a critical synthesis of current knowledge by examining therapeutic strategies through the lens of their translational challenges and failures. This narrative review highlights how interspecies variability of glial phenotypes, shifting neuroprotective versus neurotoxic states, limited biomarker stratification, and delivery barriers have constrained trials, such as anti-triggering receptor expressed on myeloid cells 2 (anti-TREM2) antibodies in AD and glial cell line-derived neurotrophic factor (GDNF) in PD. By analyzing these obstacles across major neurodegenerative disorders, this review argue that the next stage of glial medicine requires precision approaches that integrate stage-specific phenotyping, biomarker-guided patient selection, and innovative delivery platforms. Understanding not only what has been tried but why translation has stalled is essential to chart a roadmap for effective, disease-modifying glial therapies in the aging brain.},

Although the etiology of ALS is unknown, it is thought that factors such as diet, the environment, and lifestyle habits play a role. The pathogenesis of ALS includes alterations in glutamate neurotransmission, oxidative stress, mitochondrial dysfunction. Drugs such as riluzole, edaravone, dextromethorphan/quinidine combinations, and the administration of tofersen by injection are approved treatment options for ALS although a number of other agents are being examined in clinical trials. Despite these developments, the availability of effective treatment options is limited.

abstract = {BACKGROUND: Glaucoma Research Foundation's third Catalyst for a Cure team (CFC3) was established in 2019 to uncover new therapies for glaucoma, a leading cause of blindness. In the 2021 meeting "Solving Neurodegeneration," (detailed in Mol Neurodegeneration 17(1), 2022) the team examined the failures of investigational monotherapies, issues with translatability, and other significant challenges faced when working with neurodegenerative disease models. They emphasized the need for novel, humanized models and proposed identifying commonalities across neurodegenerative diseases to support the creation of pan-neurodegenerative disease therapies. Since then, the fourth Catalyst for a Cure team (CFC4) was formed to explore commonalities between glaucoma and other neurodegenerative diseases. This review summarizes outcomes from the 2023 "Solving Neurodegeneration 2" meeting, a forum for CFC3 and CFC4 to share updates, problem solve, plan future research collaborations, and identify areas of unmet need or opportunity in glaucoma and the broader field of neurodegenerative disease research.

MAIN BODY: We summarize the recent progress in the field of neurodegenerative disease research and present the newest challenges and opportunities moving forward. While translatability and disease complexity continue to pose major challenges, important progress has been made in identifying neuroprotective targets and understanding neuron-glia-vascular cell interactions. New challenges involve improving our understanding of the disease microenvironment and timeline, identifying the optimal approach(es) to neuronal replacement, and finding the best drug combinations and synergies for neuroprotection. We propose solutions to common research questions, provide prescriptive recommendations for future studies, and detail methodologies, strategies, and approaches for addressing major challenges at the forefront of neurodegenerative disease research.

CONCLUSIONS: This review is intended to serve as a research framework, offering recommendations and approaches to validating neuroprotective targets, investigating rare cell types, performing cell-specific functional characterizations, leveraging novel adaptations of scRNAseq, and performing single-cell sorting and sequencing across neurodegenerative diseases and disease models. We focus on modeling neurodegeneration using glaucoma and other neurodegenerative pathologies to investigate the temporal and spatial dynamics of neurodegenerative disease pathogenesis, suggesting researchers aim to identify pan-neurodegenerative drug targets and drug combinations leverageable across neurodegenerative diseases.},

abstract = {BACKGROUND: Neurodegenerative diseases—including Alzheimer’s, Parkinson’s, and amyotrophic lateral sclerosis (ALS)—as well as autoimmune disorders with neurodegenerative features such as multiple sclerosis (MS), present an escalating global challenge. Current diagnostics often detect pathology too late, and most treatments focus on symptom relief rather than disease modification. There is an urgent need for tools that enable early detection and precision-targeted intervention.

MAIN BODY: Nanotechnology offers unique advantages in this space, enabling early molecular detection, targeted drug delivery, and theranostic systems. Engineered nanocarriers, biosensors, and responsive nanodevices are being tailored to disease-specific features such as oxidative stress in AD or neuroinflammation in MS. Yet, issues like biocompatibility, clinical scalability, and long-term safety remain barriers to translation. Artificial intelligence (AI) enhances nanomedicine by improving biomarker sensitivity, stratifying patients, and enabling predictive disease modeling. From AI-guided nanoparticle design to closed-loop delivery systems and digital twin models, these technologies work synergistically to support real-time, personalized care. Still, critical challenges—including algorithmic bias, lack of explainability, heterogeneous datasets, and limited regulatory clarity—impede clinical integration. Additionally, high system complexity and cost risk excluding low-resource settings unless inclusive, scalable alternatives are pursued.

CONCLUSION: The convergence of AI and nanotechnology is reshaping neurodegenerative disease care, moving from reactive to proactive, personalized neurology. Realizing this promise requires cross-sector collaboration, ethical foresight, and translational rigor to ensure these innovations are safe, equitable, and accessible to all patients.

abstract = {UNLABELLED: Frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) are progressive neurodegenerative diseases with unclear etiology. Mutations in the TBK1 gene are associated with an increased risk of both FTD and ALS, presenting a diverse phenotype that includes the behavioral variant of FTD, primary progressive aphasia, and pure ALS. This mutation is rare, and to date, only one case report on TBK1-related clinical manifestations has been published in Brazil.

OBJECTIVE: To investigate the association between TBK1 gene mutations and the clinical manifestations of FTD and ALS in a Brazilian family, documenting the clinical history and disease progression of three first-degree relatives. Additionally, to conduct a literature review to better understand the impact of this mutation and its implications for neurological practice.

METHODS: Clinical data were collected from three patients in the same family who were receiving care at Dom Pedro II Geriatric Hospital and Central Hospital of the Irmandade da Santa Casa de Misericordia de São Paulo, including information on clinical symptoms, disease progression, and complementary exams - particularly genetic testing to detect and confirm the diagnosis. A detailed analysis of the existing literature on the disease was also conducted to better understand the implications of this mutation.

RESULTS: Three siblings affected by the TBK1 gene mutation were documented, with a unique family history suggesting that this genetic alteration has affected the lineage for several generations.

CONCLUSION: Although rare, frontotemporal dementia with accompanying motor deficits is of significant relevance to neurologists due to its poor prognosis and the potential familial impact on descendants.},

abstract = {BACKGROUND: Viral infections have been implicated in the pathogenesis of neurodegenerative diseases (NDs); however, evidence linking specific viruses to Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS) remains inconclusive. This study conducted a meta-analysis and systematic review to investigate these associations.

METHODS: Thorough searches were conducted across Embase, PubMed, Cochrane Library, Web of Science and Scopus until May 18, 2025, to identify observational studies investigating the relationship between viral infections and the risk of NDs, including AD, PD, and ALS. Meta-analyses were executed using a random-effects model with Stata MP18.0.

RESULTS: A total of 34,417 articles were identified, of which 73 met the eligibility criteria for inclusion in the meta-analysis, and 48 were included in the systematic review. The analysis demonstrated that infections with cytomegalovirus (CMV) (odds ratio [OR] = 1.41; 95% confidence interval [CI]: 1.03, 1.93), severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (OR = 1.88; 95% CI: 1.53, 2.32), hepatitis C virus (HCV) (OR = 1.39; 95% CI: 1.14, 1.69), and human herpesvirus (HHV) (OR = 1.24; 95% CI: 1.02, 1.51) were associated with an increased risk of AD. Regarding PD, infections with hepatitis B virus (HBV) (OR = 1.18; 95% CI: 1.04, 1.35) and HCV (OR = 1.29; 95% CI: 1.18, 1.41) were identified as risk factors. Conversely, no significant correlation was found between any viral infection and the risk of ALS.

CONCLUSION: This meta-analysis supports the role of select viral infections in AD and PD pathogenesis. However, no association was found between viral infections and ALS, warranting further large, multicenter, and longitudinal studies to elucidate mechanisms and confirm causality.},

abstract = {Herein, we report two autopsy cases of familial ALS with a p. L127S (L126S) SOD1 variant. Case 1 involved a 62-year-old woman who presented with lower-extremity muscle weakness with lower motor neuron signs. The patient developed bulbar palsy and died of respiratory failure 9 years after onset. Case 2 (the second son of Case 1) presented with lower-extremity muscle weakness at the age of 38 years, with upper and lower motor neuron signs and died of respiratory failure 8 years after onset. The pathological findings in both cases predominantly consisted of lower motor neuron loss and degeneration of the lateral and posterior funiculi. Numerous conglomerate hyaline inclusions (CHIs) were observed in the remaining motor neurons. Vacuole formation was observed inside the inclusions, sometimes with granular structures. Some inclusions were positive for ubiquitin, p62, and SOD1. Electron microscopy revealed that CHIs were composed of neurofilaments and expanded mitochondria. By literature review, ALS with p. L127S disclosed a male-dominant incidence rate, a variety of ages at onset, and low penetrance. The initial symptom was exclusively lower limb weakness. One-third of the patients only showed lower motor neuron signs and half did not present with bulbar symptoms. The neuropathological findings commonly observed in ALS with p. L127S variants were mainly the degeneration of lower motor neurons and the sensory system, including the posterior column, Clarke's nucleus, and the associated cerebellar system. The formation of intracytoplasmic hyaline inclusions was also a prominent feature. ALS with p. L127S variant should be included in the possible diagnosis of slowly progressive muscle weakness in the lower extremities, with or without family history or upper motor neuron signs. The loss of lower motor neurons and the accumulation of neurofilaments in the remaining neurons are key to the pathological diagnosis for ALS with p. L127S variant.},

abstract = {Aluminium-sulfur (Al-S) batteries have emerged as a promising post-lithium alternative owing to aluminium's abundance, safety, and high theoretical capacity. However, their practical implementation is impeded by key challenges such as sluggish Al[3+] redox kinetics, polysulfide shuttle effects, and volumetric changes of the electrodes during cycling. This review critically analysis recent advancements in host structural design engineering, new electrocatalysts, and electrolyte aimed at overcoming these limitations. Advanced host frameworks include 2D/3D porous structures, MXene-based multilayers, and single-atom doped materials that facilitate efficient sulfur confinement, enhance conductivity, and catalyse redox reactions. Embedded catalysts like Mo6S8 and CoS2 within nitrogen-doped carbons lower the decomposition barrier of Al2S3, promote stable Al-polysulfide conversion, and extend cycle life. Electrolyte optimization through ionic liquids, molten salts, and halide-modified systems further enhances ion mobility, suppresses passivation, and supports stable sulfur utilization. Emerging hybrid electrolytes combining high-donicity solvents with ionic or molten salt phases offer synergistic gains in redox kinetics and thermal stability. Density functional theory (DFT) guided designs elucidate key host-electrolyte-polysulfide interactions, revealing pathways for tailored material selection and performance enhancement. These integrated strategies pave the way for high-energy, long-lasting Al-S batteries that perform reliably at both room and elevated temperatures.},

abstract = {Neurodegenerative diseases (NDD), a collection of disorders with different underlying causes and clinical presentations, are recognized as a major area of concern of our society today. The most common NDD are Parkinson's disease (PD), Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS), and Huntington's disease, each one of them being characterized by the progressive degradation of nerve cells and accumulation of misfolded and aggregated proteins in the affected brain region. Diagnosing NDD is challenging, due to the heterogeneity of the disease and the overlap of symptoms. Yet, early detection and accurate diagnosis are crucial for effective NDD management. With the emergence of disease-modifying therapies for AD, monitoring disease progression and treatment success is becoming essential. The future of NND diagnostics is focusing on developing less invasive, cost-effective strategies that enable early NDD identification and detection with improved patient outcomes. The integration of biotechnology and nanotechnology is seen as crucial for advancing the analytical science aspect of NDD. The creation of these innovative tools and methodologies is on the verge of enabling new possibilities for clinical diagnostics, but is also faced with several hurdles that will be critically evaluated.},

abstract = {The transition from reconstructive to regenerative strategies in vascular surgery has intensified the need for grafts that are biocompatible, growth-capable, and resistant to thrombosis. Addressing this challenge, Park et al. introduce a groundbreaking method for engineering fully biological, endothelialized tissue-engineered vascular conduits (TEVCs) using decellularized human umbilical arteries (dHUAs) coated with human induced pluripotent stem cell-derived endothelial cells (hiPSC-ECs). These constructs undergo shear stress training in bioreactors, mimicking physiological blood flow to enhance endothelial functionality and anti-thrombotic properties. Upon implantation in animal models, the grafts showed long-term patency, resistance to thrombosis, and progressive replacement of hiPSC-ECs by host endothelial cells, highlighting their regenerative and integrative potential. The study emphasizes the pivotal role of hemodynamic conditioning and key regulators such as KLF2 in promoting endothelial quiescence and vascular homeostasis. It further explores alternative strategies like endothelial colony-forming cells (ECFCs) and microfluidic systems for flow-induced maturation. Clinically, this approach offers a promising, scalable avenue for patient-specific, immune-compatible vascular grafts applicable in congenital heart disease, dialysis access, vascular grafts and coronary bypass. While challenges such as long-term durability and mechanical reinforcement remain, this research marks a transformative step toward functional, off-the-shelf vascular grafts. Park et al.'s work bridges biomimicry with regenerative medicine, paving the way for next-generation vascular therapies rooted in endothelial mechanobiology and personalized bioengineering.},

abstract = {Neurodegenerative disorders (NDDs), characterized by a progressive loss of neurons and cognitive function, are a severe burden to human health and mental fitness worldwide. A hallmark of NDDs such as Alzheimer's disease, Huntington's disease, Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS) and prion diseases is disturbed cellular proteostasis, resulting in pathogenic deposition of aggregated protein species. Autophagy is a major cellular process maintaining proteostasis and integral to innate immune defenses that mediates lysosomal protein turnover. Defects in autophagy are thus frequently associated with NDDs. In this review, we discuss the interplay between NDDs associated proteins and autophagy and provide an overview over recent discoveries in inborn errors in canonical autophagy proteins that are associated with NDDs. While mutations in autophagy receptors seems to be associated mainly with the development of ALS, errors in mitophagy are mainly found to promote PD. Finally, we argue whether autophagy may impact progress and onset of the disease, as well as the potential of targeting autophagy as a therapeutic approach. Concludingly, understanding disorders due to inborn errors in autophagy-"autophagopathies"-will help to unravel underlying NDD pathomechanisms and provide unique insights into the neuroprotective role of autophagy, thus potentially paving the way for novel therapeutic interventions.},
