Values are given as mean ± standard deviation. For statistical values, Age and Education (year) between HC, PD, and ICD groups were assessed by Kruskal–Wallis nonparametric one-way analysis of variance (Age: HC vs. PD = 0.04, HC vs. ICD and PD vs. ICD > 0.45, Education (year): HC vs. PD = 0.04, HC vs. ICD and PD vs. ICD > 0.59). Disease duration (year), UPDRS, H&Y, S&E, QUIP-RS between PD and ICD groups were assessed by Wilcoxon rank-sum test
