Conditions
Summary
The main objective of this study is to investigate in real-time the neuronal correlates of paroxysmal dyskinesia episodes related to the PRRT2 mutation within this subgroup of patients (who can control paroxysmal dyskinesia episodes), and more specifically, the pathological role of the reciprocal influence between the striatum and the cerebellum in paroxysmal dyskinesia episodes.
Eligibility
Inclusion Criteria2

- Affiliated with a health insurance system or a beneficiary of such a system. Individuals aged 18 to 75 years. Signature of informed consent
Exclusion Criteria2
- Individuals under guardianship. Individuals not residing in France. Individuals unable to comply with protocol constraints (compliance with visit schedules and ability to perform required tasks).
- Individuals undergoing an exclusion period for another research study. Contraindications to MRI
