Three PD patients were not started on medication because of mild symptoms. The nonresponders were only started on monoamine oxidase B inhibitors and/or dopamine receptor agonists. Response in the remaining cases was not documented in provider notes.
Age at scan was not significantly different between the PD and non-PD groups (two-sample t-test, t = 1.33, P = 0.19, unequal variances assumed).
L indicates left; non-PD, patients without PD and with negative DaT scans; R, right.
