Degeneration of the dopaminergic system in Parkinson's disease and longstanding exposure to dopaminergic drugs may cause reward system malfunction. This may manifest as addiction to L-dopa and behavioral disturbances associated with the impulse control system. These disturbances include: gambling, excessive spending (shopping), hypersexuality and binge eating. We included one such patient's personal story to emphasize the devastating consequences of these potentially reversible phenomena: the patient describes in his own words how gambling induced by an exposure dopamine agonist therapy significantly worsened his disease-related difficulties.
