Purpose
The purposes of this study are to identify persons with rapid-onset dystonia-parkinsonism (RDP) or mutations of the RDP gene, document prevalence of the disease, and map its natural history.

- RDP Severity [ Time Frame: Visit 1 ] [ Designated as safety issue: No ]Only one study visit required. History of symptom onset and duration will be obtained and current degree of severity assessed.
- Presence of neuropsychiatric disease [ Time Frame: Visit 2 ] [ Designated as safety issue: No ]Psychiatric interview and cognitive assessment will be performed to examine presence or absence of symptoms.

Detailed Description:
Rapid-onset dystonia-parkinsonism (RDP) is a rare, movement disorder with variable characteristics ranging from sudden onset (hours to days) of severe dystonic spasms to gradual onset of writer's cramp. RDP has elements of both dystonia and Parkinson's disease—two neurological diseases with motor and neuropsychological symptoms that hinder the quality of life. An internal trigger associated with extreme physiological stress has been reported prior to abrupt symptom onset of RDP.
This study, which is a continuation of an earlier study begun by Dr. Allison Brashear, aims to more clearly identify the characteristics associated with RDP and to explore whether mutations in the RDP gene are associated with atypical dystonias, Parkinson's disease, and other movement disorders.
Physicians from around the world who suspect their patients may have RDP or other movement disorders will send videotaped neurological assessments of their patients and blood samples for genetic analysis.
Eligibility| Ages Eligible for Study: | 2 Years and older |
| Genders Eligible for Study: | Both |
| Accepts Healthy Volunteers: | No |
| Sampling Method: | Non-Probability Sample |
Selection will take place predominantly via primary care clinics, i.e., physician referrals when patients present with a movement disorder suspicious for RDP.
Inclusion Criteria:
- clinical presentation consistent with RDP or confirmed diagnosis of RDP
