An Observational Study of Individuals With Isolated Dystonia
This is an observational study in individuals with isolated (or primary) dystonia that involves more than one body region. The purpose of the study is to collect detailed information to help your physician and other researchers understand how dystonia impacts your and other patients' lives and how the disease changes over time. The study may also help researchers better understand the clinical scales that are commonly used to evaluate dystonia symptoms and how they affect various areas of life such as well-being, pain, relationships and social interactions, and progress over time. Because this is an observational study, you will not receive any interventional treatment in the study.
