Impulse control disorders in Parkinson's disease.
Since the original descriptions of hedonistic homeostatic dysregulation syndrome and pathological gambling in Parkinson's disease, impulse control disorders, such as compulsive spending, punding, or binge eating, are increasingly recognized. Although the term hedonistic homeostatic dysregulation syndrome has been supplanted by the concept of the dopamine dysregulation syndrome, the features of severe dyskinesias, cyclical mood disorder with hypomania or manic psychosis, and impairment of social and occupational functioning in the setting of increased intake of antiparkinson therapy remain. At this time, impulse control disorder is defined as maladaptive behaviors that emerge with disease progression and increasing antiparkinson medications. These behaviors may be disruptive, such as punding, or destructive, such as compulsive spending, gambling, binge eating, or hypersexuality.
