Compulsive Singing Associated With a Dopamine Agonist in Parkinson DiseaseKataoka, Hiroshi MD, PhD; Ueno, Satoshi MD, PhDCognitive and Behavioral Neurology: June 2010 - Volume 23 - Issue 2 - p 140-141 doi: 10.1097/WNN.0b013e3181c12af2 Case Reports Abstract Author Information Objective To describe a patient with Parkinson disease in whom compulsive singing developed without other types of pathologic behavior after starting treatment with pergolide. Material An 82-year-old woman with Parkinson disease was given pergolide (250 μg/d), without modifying the doses of other medications. Results She started to hum the same melody and often sang songs repeatedly. Pergolide was discontinued, and the episodes of repetitive humming and singing were markedly decreased. Conclusions Our observations suggest that a dopamine agonist may contribute to compulsive singing in Parkinson disease.
