Role of Deep Brain Stimulation on Social Cognition in Parkinsonian Patients
Role of Deep Brain Stimulation on Social Cognition in Parkinsonian Patients
Parkinson's disease (PD) is usually responsible of cognitive and behavioral non-motor signs
 with a major impact on the quality of life. Social cognition is a complex system relying on
 emotion recognition (neurons mirror system, NMS), the theory of mind (with its two parts:
 emotional and cognitive), but also on the social and cultural environment and the personal
 history. The first step in this model is represented by the NMS, which seems to be altered in
 PD patients for both positive and negative emotions as shown in our preliminary study. The
 investigator purpose is to investigate the role of the treatment (levodopa and deep brain
 stimulation) on the functioning of the NMS.
