PD, patients with Parkinson’s disease; HC, healthy controls; FD, framewise displacement of Jenkinson; MMSE, Mini-Mental State Examination; HY, Hoehn and Yahr scale; UPDRS-III, part three (motor part) of Unified Parkinson’s Disease Rating Scale; LEDD, levodopa equivalent daily dose. Data are presented as mean ± standard deviation. The statistical p-value was obtained by two-sample t-tests with a significance level of p < 0.05.
