  1. H&Y Hoehn and Yahr Staging Scale, QUIP-RS Questionnaire for Impulsive-Compulsive Disorders in Parkinson’s Disease Rating Scale, S&E Schwab and England Activities of Daily Living Scale, UPDRS Unified Parkinson’s Disease Rating Scale (Part I/II/III/total)
  2. 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
