Social Cognition Dysfunctions in Parkinson's Disease

"The evaluation of social cognition will be carried out using questionnaires and a point lights computer test. During the computer test, participants have to watch several short sequences of interactions between two silhouettes and give an interpretation of the scene.~Patients will be evaluated twice: one time before the surgery and a second time 1 year after surgery.~Healthy volunteers will be evaluated only one time."

Quality of life will be assessed using a self-administered questionnaire in the patients group only.
