Shame and embarrassment scores strongly correlate with patient's quality of life, anxiety and depression ratings. However, the neurobiology of shame and embarrassment in PD and the influence of dopaminergic replacement therapy (DRT) is poorly understood.\n\nThe aim of this study is to characterize how brain structures and neuronal networks involved in Parkinson's disease-related shame, non-Parkinson's disease related shame and neutral control scenarios, are modulated by dopaminergic replacement therapy. For this purpose, functional MRI and connectivity measures between the basal ganglia and shame-related network will be analyzed while PD patients will perform a shame-induction task during both ON- (i.e. during the effect of DRT) and OFF-DRT (i.e. during the withdrawal of DRT) conditions. Correlation with clinical measures will be made."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "maximumAge"=>"80 years", "minimumAge"=>"18 years", "samplingMethod"=>"NON_PROBABILITY_SAMPLE", "studyPopulation"=>"PD patients will be recruited from the outpatient movement disorder clinic of the Neurology Department at the Geneva University Hospital (HUG).
