In the past decade, impulse control disorders, punding, and dopamine dysregulation syndrome (which we refer to collectively as disinhibitory psychopathologies) have been increasingly recognized in treated patients with Parkinson's disease. Practicing neurologists must understand these problems to limit potential harm. In this article, we summarize current knowledge regarding these behavioral disorders, including phenomenology, epidemiology, pathophysiology, and treatment.
