|Condition or disease|
This collaborative, international effort has one primary goal. This is to create a biospecimen repository and associated clinical database to be used as a resource for dystonia and related disease research. Across sites, the investigators hope to enroll at least 5,000 adult patients.
Subjects of this study will be asked to complete a neurological exam which will be video recorded, complete some questionnaires, and donate a blood sample. A study visit will take between 45 minutes and 1 hour. All subjects will be asked to return every 1, 2, 3, or 4 years for a one hour follow-up visit. People may participate in this study without agreeing to participate in the follow-up visits.
