Dopamine Transporter Imaging in Psychogenic Parkinsonism and Neurodegenerative Parkinsonism with Psychogenic Overlay: A Report of Three Cases

Chizoba C. Umeh, Zsolt Szabo, Gregory M. Pontone, Zoltan Mari


Background: Differentiating psychogenic parkinsonism from neurodegenerative Parkinson's disease (PD) with psychogenic features is a diagnostic challenge.

Case report: We report a detailed longitudinal clinical description of three cases presenting with suspected psychogenic parkinsonism. Dopamine transporter single-photon emission computed tomography (DAT-SPECT) was used as a supplemental diagnostic study and influenced clinical management.

Discussion: DAT-SPECT quantified the integrity of the striatal dopaminergic system in these cases of clinically uncertain parkinsonism and supported clinical decision-making.
