Special Issue Information

Dear Colleagues,

Multiple Sclerosis (MS) is a chronic, immune-mediated disease of the central nervous system (CNS), characterized by neuroinflammation, neurodegeneration, and varying degrees of disability. Although remarkable progress in neuroimaging, biomarker discovery, and treatment has been achieved, significant challenges persist, including the lack of effective therapies to address compartmentalized or smouldering inflammation, which appears to drive disability accumulation even from the earliest stages of the disease.

The recent 2024 revision of the McDonald criteria introduces a biologically based definition of the disease and allows for an earlier diagnosis, even from the stage of radiologically isolated syndrome (RIS), through advanced imaging sequences, novel biomarkers, and the inclusion of the optic nerve as a fifth topography. Novel therapies, including Bruton's Tyrosine Kinase Inhibitors (BTKis), chimeric antigen receptor T (CAR-T) cell therapies, and remyelination therapies, are being tested and hold promise for the near future.

This Special Issue, “Advances in Multiple Sclerosis: From Pathogenesis to Therapeutics”, focuses on the rapidly evolving landscape of MS. We invite researchers with contributions exploring all aspects of MS, including novel biomarkers of disease activity and progression, clinical and real-world evaluations of disease-modifying therapies (DMTs), as well as innovative symptomatic and rehabilitative strategies. Special attention will be given to studies addressing smouldering disease mechanisms, including the role of microglia, and to those examining clinical, radiological, and biochemical outcomes for the assessment of CNS compartmentalized inflammation.

Through cutting-edge research, this Special Issue aims to advance both knowledge and practice in MS by bridging pathophysiological, diagnostic, and therapeutic aspects of the disease. Authors are welcome to submit original articles, reports on novel treatment strategies and advances in decision making, clinical outcome studies, comparative studies, narrative reviews, scoping reviews and systematic reviews, and meta-analyses.

Multiple sclerosis (MS) is a chronic immune-mediated demyelinating disorder of the central nervous system, traditionally considered distinct from neuromuscular diseases, which primarily affect the peripheral nervous system, neuromuscular junction, or skeletal muscle. Growing clinical and experimental evidence, however, indicates that certain neuromuscular disorders may coexist with MS or shared overlapping pathophysiological, immunological, and metabolic mechanisms. This narrative review summarizes reported associations between MS and neuromuscular diseases, with particular focus on well-characterized overlaps such as Leber hereditary optic neuropathy (LHON)-associated MS (Harding’s disease), combined central and peripheral demyelination (CCPD), and myasthenia gravis (MG) co-occurring with MS. Additional associations with Charcot–Marie–Tooth disease, mitochondrial disorders with MS-like phenotypes, inherited and autoimmune myopathies, and rare syndromes such as Guillain–Barré syndrome are also discussed. This review highlights proposed mechanisms potentially linking these conditions, including immune dysregulation, T- and B-cell-mediated autoimmunity, antibody-driven demyelination, mitochondrial dysfunction, impaired neuromuscular transmission, and molecular mimicry. Limitations of the current literature are acknowledged, particularly the predominance of case reports for rare associations and the frequent lack of systematic screening for coexisting disorders. By integrating evidence from case series, cohort studies, and mechanistic research, this review provides a comprehensive overview of the biological and clinical intersections between MS and neuromuscular diseases. Enhanced understanding of these overlaps may improve diagnostic accuracy, guide individualized management strategies, and inform future research on shared neuroimmunological and neurodegenerative pathways.

Background/Objectives: People with MS continue to experience relapses despite the use of disease-modifying therapies. This has motivated growing interest in the potential of non-pharmacological factors to reduce relapse risk. However, previous studies have been heterogeneous, and current clinical guidelines lack clarity on which measures should be incorporated into routine care. We aim to conduct an umbrella review of systematic reviews with meta-analyses to determine the current evidence on non-pharmacological exposures associated with relapse risk in MS. Methods: We searched PubMed, Embase and Cochrane to identify systematic reviews with meta-analyses that evaluated the association between non-pharmacological exposures and relapse risk. We included observational studies that reported on relapses as an outcome. The effect sizes (relative risk [RR] or standardized mean difference [SMD]) and certainty of evidence were assessed using components of the GRADE framework. Results: We screened 3366 articles and identified 11 systematic reviews for inclusion. Protective factors were breastfeeding (RR 0.63, high certainty), pregnancy (SMD −0.52, moderate certainty), menopause (SMD −0.5, low certainty), autumn months (RR 0.97, moderate certainty) and increasing levels of vitamin D (RR 0.9, low certainty). Risk factors were early postpartum period (RR 1.87, moderate certainty) and stress (d = 0.53, moderate certainty). Influenza vaccination (low certainty), COVID-19 infection (low certainty), and vitamin D levels above 50 nmol/L (low certainty) were not statistically associated with relapse risk. Conclusions: Our umbrella review highlights the need for more robust studies to strengthen the certainty of evidence on non-pharmacological exposures and relapse risk in people with MS. Current findings support promoting breastfeeding, careful disease management throughout the pregnancy–postpartum period, and the implementation of stress mitigation strategies. Full article
