Only exception: abnormal eating
1167 patients with Parkinson’s disease in South Corea were administered the Minnesota questionnaire to detect abnormal compulsions. 10% had abnormal compulsions, especially punding (tidying, cleaning and cataloging objects without any purpose) (4.2%), eating (3.4%), sexual behaviors (2.8%), shopping (2.5%) and gambling (1.3%). All these abnormal behaviors were related to the dose of dopamine agonist taken, except punding, which was related to the dose of levodopa, and eating, which was not related to the dose of any drug.
