Study Details

Brief summary:

The purpose of this study is to (1) investigate the effect of known dystonia-causing mutations on brain structure and function, to (2) identify structural brain changes that differ between clinical phenotypes of dystonia, and to (3) collect DNA, detailed family history, and clinical phenotypes from patients with idiopathic dystonia with the goal of identifying new dystonia-related genes. Investigators will be recruiting both healthy control subjects and subjects with any form of dystonia. For this study there will be a maximum of two study visit involving a clinical assessment, collection of medical and family history, task training session, an MRI using the learned tasks, and finally a blood draw for genetic analysis. In total, these visits will take 3-5 hours. If the dystonia subjects receive botulinum toxin injections for treatment, the participants and their matched controls will be asked to come for a second visit.

Interventions and Outcome Measures

Arms

Dystonia group

Both groups will have blood drawn, undergo clinical assessments, the collection of medical and family history, and an Magnetic Resonance Imaging. This is an observational study and there is no intervention.

Control Group

Both groups will have blood drawn, undergo clinical assessments, the collection of medical and family history, and an Magnetic Resonance Imaging. This is an observational study and there is no intervention.

Interventions

Magnetic Resonance Imaging

Study interventions are minimal risk.

Primary outcome measure

  • Structural or functional imaging of dystonia and control groups [ Time Frame: 3-5 hours at each study visit ]
  • Genetic Analysis of dystonia and control groups [ Time Frame: 30 min ]
