Prevalence rates of multiple sclerosis (MS) suggest an interrelationship between genetic and environmental factors, ranging worldwide.
Objectives
Clinical and epidemiological characterization of MS patients in João Pessoa, Paraíba city.

Motor symptoms (65.5%) and relapsing-remitting clinical form (78.2%) predominated; the average of the Expanded Disability Status Scale (EDSS) scores was 3.5 and 72% used a type of immunomodulatory drug. There was a positive correlation between the number of outbreaks and the duration of the disease with EDSS scores.
