What this trial studies
This study aims to explore the neuronal correlates of paroxysmal dyskinesia episodes in patients with a PRRT2 mutation using functional MRI and EEG. It focuses on understanding the interactions between the striatum and cerebellum during these episodes, particularly during the prodromal phase and the refractory period. By analyzing brain activation and connectivity, the study seeks to uncover the mechanisms behind the control of abnormal movements and the perception of action control in affected individuals.
Who should consider this trial
Good fit: Ideal candidates are individuals aged 18 to 75 with a PRRT2 mutation who can control their paroxysmal dyskinesia episodes.
Not a fit: Patients who are unable to comply with the study protocol or do not reside in France may not benefit from this study.
Why it matters
Potential benefit: If successful, this research could lead to improved understanding and management of paroxysmal dyskinesia, potentially enhancing treatment options for patients.
How similar studies have performed: While the specific approach of this study is novel, similar studies using functional imaging techniques have shown promise in understanding movement disorders.
