The purpose of this study is to validate (or properly confirm) the use of a modified version of the Unified Multiple System Atrophy Rating Scale (UMSARS) that incorporates structured questions and additional instructions developed by Biohaven Pharmaceuticals. The study personnel will conduct structured interviews with study subjects about their experience with MSA, their symptoms, and how their disease effects their life. These items are rated on a scale used to measure MSA symptoms, called the Unified Multiple System Atrophy Rating Scale.
