Use of BART Coupled With EEG in the Early Diagnosis of Behavioral Disorders in Parkinson's Disease

Centre Hospitalier Universitaire de Besancon80 enrolled

Overview

The Balloon Analogue Risk Task \[BART\] is an experimental task modelizing risky behaviors. In Parkinson disease, the correlation between BART and modifications of cerebral activity in ventral striatum has been shown. BART thus seems to be particularly adapted for modelization of HYPERdopaminergic behavioral disorders \[TYPER\] into Parkinsonian patients. Previously, a version of the BART performed with EEG has been specifically developped by the Centre d'Investigation Clinique of Besançon University Hospital, in collaboration with the Clinical and integrative neurosciences laboratory. Preliminary data suggest that the analysis of evoked potentials including Feedback-related Negativity \[FRN\], P300 wave, and Reward Positivity \[RewP\], could help assessing the motivational and attentional attributes of decision making and the delayed treatment of any reward. The hypothesis of the study that the EEG version of the BART could help predicting the risk to develop TYPER into Parkinsonian patients treated by dopaminergic in routine care.
