Multiple Sclerosis (MS) is a complex autoimmune disease affecting the central nervous system, characterized by diverse symptoms based on lesion locations. Familial MS (FMS) indicates a genetic predisposition, potentially leading to a more severe disease course than sporadic MS, which lacks familial clustering. This distinction is critical for diagnosing and treating MS, particularly in the Iraqi patient population. The study aims to evaluate and compare the clinical and radiological features of FMS and sporadic MS among patients at the Baghdad Teaching Hospital's MS outpatient clinic. In this observational retrospective cross‐sectional study, conducted from July 1, 2023, to December 31, 2023 at the Baghdad M.S outpatient clinic within the Medical City complex in Baghdad, Iraq, 100 MS patients were enrolled, with an equal division between FMS (n=50) and sporadic MS (n=50) cases. Participants were selected based on a definitive MS diagnosis, with FMS patients having a first or second‐degree relative with MS. Data were collected via a questionnaire focusing on demographics, clinical presentations, MRI findings and EDSS scores. Analysis was performed using SPSS version 26, employing Pearson Chi‐square tests and Fisher's Exact test, with significance set at P=0.05. The demographic analysis revealed a predominant female representation (89%), with a significant age range between 20‐30 years (48%). Time to diagnosis was notably longer for FMS cases, averaging 25.235 months, compared to 10.295 months for sporadic cases (P=0.002). Clinical presentations did not significantly differ between groups, but FMS cases exhibited greater disability severity, with higher EDSS scores indicating moderate to severe disability in 31% of FMS cases compared to only 19% in sporadic cases (P=0.035). MRI findings showed a higher prevalence of spinal cord and corpus callosum lesions in FMS (P=0.001 and P=0.027, respectively), with no significant differences in juxtacortical, cortical, or infra tentorial lesions. This study illuminates that MS mainly affects females in their twenties and thirties, with familial MS cases taking longer to diagnose than sporadic ones. Familial cases exhibited more severe disabilities and more lesions in the spinal cord and corpus callosum. This indicates a complex interplay between genetics and MS, underscoring the importance of further research to enhance our understanding of the disease.
