Dystonia is a disorder characterized by excessive involuntary contraction of muscles with repetitive and patterned movements. The isolated dystonias are the most common type of dystonia and include Limb dystonias (like writer's cramp), Cervical dystonia (spasmodic torticollis), Laryngeal dystonias (like spasmodic dysphonia), and Craniofacial dystonias (like blepharospasm). The purpose of this study is to create resources to help learn more about the isolated dystonias, myoclonus dystonia, and dopa-responsive dystonia and to develop and validate various dystonia rating scales.


Study Type: Observational
Official Title: Natural History and Biospecimen Repository for Dystonia; Comprehensive Rating Tools for Cervical Dystonia; Validity & Reliability of Diagnostic Methods & Measures of Spasmodic Dysphonia

Estimated Primary Completion Date: June 2017 (Final data collection date for primary outcome measure)
Cervical dystonia
People diagnosed with cervical dystonia
Laryngeal dystonia
People diagnosed with laryngeal dystonia
Other voice disorders

Craniofacial dystonia
People diagnosed with craniofacial dystonia (including blepharospasm, meige syndrome, and oromandibular dystonia)
Limb dystonia
People diagnosed with limb dystonia
All other isolated dystonias
People diagnosed with any isolated dystonia not listed in descriptions of other cohorts
Myoclonus dystonia

Detailed Description:

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.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
People with dystonia are eligible to participate as long as they are above age 18 and fit the eligibility criteria. The coordinator at the site you contact can tell you more about this.

Inclusion Criteria:

  • Diagnosed with isolated dystonia or myoclonus dystonia or dopa-responsive dystonia
  • To be included in laryngeal dystonia group, nasolaryngoscopy (voice box exam) must have been completed to confirm diagnosis (this voice box exam is not part of the study)

Exclusion Criteria:

  • Any evidence of a secondary cause for dystonia (other than myoclonus dystonia or dopa-responsive dystonia)
  • Less than 2 months since last botulinum toxin injection
  • Inability to provide informed consent
  • Significant medical or neurological conditions that preclude completing the neurological exam
  • Significant physical or other condition that would confound diagnosis or evaluation, other than dystonia or tremor
