Brief 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.
Detailed Description:
We propose to conduct a study using functional MRI and EEG in this subgroup of patients with the PRRT2 mutation capable of triggering paroxysmal dyskinesia episodes. For both modalities, we aim to perform an analysis of the activation of regions involved in the occurrence of abnormal movements during the prodromal phase when the acquisition is not affected by movements. Using these techniques, we will also investigate the regions involved in judging control over action during phases where abnormal movements may occur before the episode (when the system is excitable) and when it is no longer possible during the refractory period (when the system is no longer excitable). Additionally, we plan to conduct a targeted analysis of functional connectivity in the striato-cerebellar pathway before the episodes (when the system is excitable) and after the episodes during the refractory period (when it is no longer excitable).
Our hypotheses are as follows: 1) there is a relationship between the cerebellum, the basal ganglia and the cortex implicated in the abnormal movements associated with the PRRT2 mutation; 2) the frontal or prefrontal cortex, the cerebellum and basal ganglia are involved in the inhibition of unwanted movements; 3) there is a distortion in the sense of control over action related to paroxysmal dyskinesia episodes.
