An Observational Study of Individuals With Isolated Dystonia

The primary goal of this observational study is to further characterize and quantify disease severity and impact (including change over time) in individuals with either segmental, multifocal, or generalized dystonia in a structured manner, utilizing and comparing various well-known scales. In addition, medication history and any intercurrent events related to the participant's health (such as, but not limited to, hospitalizations, new diagnoses, etc.) will be captured. This study will provide standardized data to support planned future interventional clinical studies in this patient population and will provide a greater understanding of the population under study and the performance of clinical ratings scales.
