Abstract
Parkinsonism can be psychogenic, and psychogenic parkinsonism is about 10% of psychogenic
movement disorder patients. Patients can present with any feature or combination of
features of organic Parkinson's disease. There are clinical clues that can lead to
the correct diagnosis, and laboratory testing with clinical neurophysiology or DAT
(dopamine transporter) scanning can be helpful as well. Patients may have both organic
Parkinson's disease and psychogenic parkinsonism, and this might be considered a psychologically
induced aggravation of the organic disorder.
