Takeaway
The dynamic functional network connectivity (dFNC) in those with Parkinson’s disease (PD) and impulse control disorders (PC-ICD) is characterized by functional engagement of local connectivity involved with the limbic circuit, which impacts emotional processing and reward-related decision making.
Why this matters
The altered dFNC not only further elucidates the pathophysiology of ICD in PD, but also indicates that measuring dFNC in PD may assist in identifying those at an elevated risk for ICD.
