Disease & Epidemiology Analysis

Multiple sclerosis is a chronic autoimmune disease affecting the central nervous system through inflammatory demyelination and neurodegeneration. Disease prevalence varies geographically but remains highest across North America and Europe, reflecting genetic susceptibility, environmental influences, and improved diagnostic capability. Women account for the majority of diagnosed patients, and disease onset typically occurs during early adulthood, creating prolonged healthcare utilization throughout life.

Relapsing-remitting multiple sclerosis represents the most common clinical phenotype at diagnosis, although many patients eventually transition toward secondary progressive disease. Primary progressive multiple sclerosis accounts for a smaller proportion of cases but contributes disproportionately to disability burden because therapeutic options remain limited. Growing recognition of radiologically isolated syndrome and earlier diagnosis are expanding opportunities for preventive therapeutic intervention.
