Abstract

This article presents an overview of anhedonia, the lowered ability to experience pleasure, in Parkinson's disease (PD). The definition, measurement, relationships with depression and apathy in PD, treatment, and hyperhedonia related to impulse-control disorder are presented and discussed. The authors present the value of a more circumscribed definition of anhedonia taking into account the distinction between anticipatory and consummatory anhedonia and propose various research approaches.
