Abstract

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.
