    Description de l'étude

    Résumé de l'étude

    Introduction:

    Repetitive behaviors (RB) constitute a broad range of symptoms across different psychiatric/neurologic disorders. The most famous are stereotypies (found in autism), compulsions (found in obsessive-compulsive-disorder, OCD) and tics (found in Gilles de la Tourette syndrome, GTS). For some patients, it is sometime difficult to distinguish the nature of the repetitive behaviors presented, however this distinction is crucial in order to chose the appropriate treatment.

    Aim:

    In our study, the investigators will try to define electrophysiological and accelerometric marker of both OCD and tics to allow objective distinction between both tics and compulsions.

    Method:

    Subjects: Both OCD and GTS patients will be recruited, 25 patients in each group.

    Protocol: our study protocol will involve two step: a step in laboratory, another step at patient home.

    * first step: both patients group will be recorded through a high density EEG and a portative EEG while doing a task of symptom provocation. Then they will get an anatomical MRI for source recontruction. Finally, the patients will have to mimic their symptom while wearing an accelerometer (a smartwatch).
    * second step: both patient groups will be recorded at home through a portative EEG while tagging their symptom through a smartwatch (also used for accelerometry). After the recording, the patients will keep the smartwatch for 2 weeks, still tagging their sympoms (compulsions or tics).
