Background: Headaches are more prevalent in patients with multiple sclerosis compared with the general population. However, headaches are still considered a rare symptom of multiple sclerosis, especially when they appear as an initial symptom. The occurrence of a headache as a symptom of radiologically isolated syndrome (RIS) is uncommon, and it can significantly increase the likelihood of developing multiple sclerosis.
Case Presentation: We report the case of a 36-year-old Iranian woman experiencing severe unilateral headaches without other multiple sclerosis symptoms. Despite normal physical and laboratory exams, cerebrospinal fluid analysis showed positive oligoclonal bands. Magnetic resonance imaging (MRI) revealed multiple demyelinating plaques consistent with RIS. She was treated with dimethyl fumarate. Subsequent MRI confirmed multiple sclerosis by showing new gadolinium-enhanced lesions. After 3 months of dimethyl fumarate treatment, her headache intensity decreased, and she remained otherwise symptom free. Written informed consent was obtained from the patient.
Conclusion: Effectively managing headaches in patients with RIS is a challenge for clinicians to improve their quality of life and delay the progression of multiple sclerosis.

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.
