Altered Dynamic Functional Connectivity in

Depression is one of the most prevalent and disturbing non-motor symptoms in Parkinson's disease (PD), with few dynamic functional connectivity (dFC) features measured in previous studies. Our aim was to investigate the alterations of the dynamics inWe performed dFC analysis on the data of resting-state functional MRI from 21Four distinct functional connectivity states were clusteredOur study demonstrated that altered network connection over time, mainly involving the DMN and CEN, with abnormal dynamic graph properties, may contribute to the presence of depression in patients with PD.
