Demographic and Clinical Data of the YNHH Cohort

PD (n = 35) Non-PD (n = 42)
Female:male 14:21 20:22
Age at DaT scan,* y 62.5 ± 11.7 65.9 ± 10.5
Onset/more affected side 10 R, 22 L, 3 unknown
Tremor 23 (66%) 21 (50%)

 Yes 25 (78%)

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.
