Access and unmet needs to multiple sclerosis care in a cohort of Argentinean patients.

Background: Multiple sclerosis (MS) has a low prevalence in Argentina. However, MS has a high burden of disease, which implies frequent neurological visits, magnetic resonance images (MRI) use and chronic MS medication during follow-up, with a high impact on the healthcare system. Therefore, MS care is essential to optimize disease management and improve patients' outcome.
