 PURPOSE: This study examined the impact of venlafaxine and bupropion on the detection of nigrostriatal degeneration by dopamine transporter (DAT)-SPECT. METHODS: 43 patients (70.7 ± 8.6y, 44% female) with [ RESULTS: Two clusters were identified. The first cluster (37% cases) showed a Parkinson's disease (PD)-like pattern: median striatal SBR/asymmetry/putamen-to-caudate z-score -4.5/4.9/-3.8. The second cluster (63%) showed symmetric reduction with normal intra-striatal gradient: median striatal SBR/asymmetry/putamen-to-caudate z-score -2.7/0.4/0.2. Patients with follow-up clinical reference diagnoses of neurodegenerative (n = 8) and non-neurodegenerative (n = 16) parkinsonism fell exclusively into the former or the latter cluster, respectively (p <
  0.001). CONCLUSION: Venlafaxine and bupropion cause uniform reduction of the striatal [
