A systematic search was performed in electronic databases and lists of references, focused on epidemiological studies of MS in Argentina. Data obtained were analyzed with the StatsDirect software. A total of 275 studies were retrieved of which 15 included. The prevalence was described in 4 studies, most of them reported a prevalence of 17 cases per 100,000 inhabitants. The incidence, prospectively described in one hospital based study, was 1.76 cases per 100,000 persons-years. In this study, 65.5% of cases were relapsing-remitting MS, 21.5% secondary progressive, 10.6% primary progressive and 2.4 progressive with relapsing MS. Female/male ratio was 1.55.
