Abstract:IntroductionImpulse control disorders (ICDs) refer to the common neuropsychiatric complication of Parkinson’s disease (PD). The white matter (WM) topological organization and its impact on brain networks remain to be established.MethodsA total of 17 PD patients with ICD (PD-ICD), 17 without ICD (PD-NICD), and 18 healthy controls (HCs) were recruited. Graph theoretic analyses and Granger causality analyses were combined to investigate WM topological organization and the directional connection patterns of key re… Show more
