Objective: To provide a review of the etiology, epidemiology, clinical features, diagnostic findings, and treatment options for multiple sclerosis (MS).
Data Sources: A PubMed search of English language articles using a combination of words: elderly; multiple sclerosis*, late onset multiple sclerosis*, etiology; screening; diagnosis; or treatment to identify original studies, guidelines, and reviews on multiple sclerosis and late-onset multiple sclerosis, published 2002 to 2013. Primary sources were then used to search for additional relevant material.
Study Selection And Data Extraction: Original studies, clinical reviews, references, and guidelines were obtained and evaluated for their clinical relevance.
Data Synthesis: The literature included guidelines and considerations for the etiology, diagnosis, screening, and management of MS.
Conclusion: MS is a chronic autoimmune disease characterized by inflammation, demyelination, and local axonal injury. It typically presents between ages 20 and 40 and largely affects women. However, 2% to 10% of individuals are diagnosed after 50 years of age. Diagnosis is based on presentation of clinical symptoms and the McDonald criteria for diagnosing MS. Management focuses on suppression of the immune system and prevention of relapses.

Background: The DNA methylation-based epigenetic clocks are increasingly recognized for their precision in predicting aging and its health implications. Although prior research has identified connections between accelerated epigenetic aging and multiple sclerosis, the chronological and causative aspects of these relationships are yet to be elucidated. Our research seeks to clarify these potential causal links through a bidirectional Mendelian randomization study.

Background: Emerging evidence implies a link between high pediatric body mass index (BMI) and an increased risk of multiple sclerosis (MS). However, previous research suggests this association is only present for adolescent obesity and not childhood obesity. The present study aimed to assess the association between pediatric obesity and risk of developing MS, and to investigate if degree of obesity and age at obesity treatment initiation affects the risk.

Observational studies have reported an association between lipoprotein(a) (Lp(a)) and immune-mediated inflammatory diseases (IMIDs). This study used Mendelian Randomization (MR) and multivariable MR (MVMR) to explore the causal relationship between lipoprotein(a) [Lp(a)] and immune-mediated inflammatory diseases (IMIDs). We performed a bidirectional two-sample mendelian randomization analyses based on genome-wide association study (GWAS) summary statistics of Lp(a) and nine IMIDs, specifically celiac disease (CeD), Crohn's disease (CD), ulcerative colitis (UC), inflammatory bowel disease (IBD), multiple sclerosis (MS), psoriasis (Pso), rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), type 1 diabetes (T1D), and summary-level data for lipid traits.

Compelling evidence suggests a significant association between antibody-mediated immune responses and multiple sclerosis (MS). However, the exact causal relationships between these immune responses and MS remain unclear. In this study, we conducted a comprehensive examination of the link between antibody-mediated immune responses and MS via Mendelian randomization (MR) analysis to identify specific infectious pathogens potentially involved in the onset and progression of MS.

Background: McDonald criteria (MC) are a globally accepted standard for the diagnosis of multiple sclerosis (MS). Misdiagnosis of MS is a common problem that has significant clinical consequences for patients. Misapplication of MC is a potential source of MS misdiagnosis.
