The goal of this study is to create a repository or an organized collection used for future research on dystonia and other diseases. Participants in this study have Dystonia. Dystonia is a rare neurological movement disorder in which muscles contract involuntarily, which can force certain parts of the body into abnormal, sometimes painful, movements or postures. It can be primary; possibly involving a genetic predisposition to the condition, or secondary, meaning it can be caused by brain injuries, toxins, and some medications. The repository will store biospecimens (such as blood and DNA), videos, and clinical information.
