  1. Values are represented as the mean ± SD. For comparisons of the demographics, p values were obtained using two-sample t-tests (p value for the gender difference was obtained using Wilcoxon rank sum test, p value for the H&Y was obtained using chi-square test). **p < 0.001. HDRS = Hamilton Depression Rating Scale; UPDRS III = Unified Parkinson’s Disease Rating Scale motor part III; H&Y = Hoehn and Yahr Staging Scale; LED = levodopa equivalent dose.
