Connectivity between the insula and precuneus may be associated with cognitive function among patients with isolated rapid eye movement sleep behavior disorder (iRBD), according to the results of a cross-sectional study published in Sleep Medicine.
Study researchers recruited patients (n=50) diagnosed by video-polysomnography with iRBD at Seoul National University Hospital Sleep Clinic and healthy controls (n=20) for this study. They assessed participants by multivariate pattern analysis on the basis of structural magnetic resonance imaging (MRI) and resting-state functional MRI scans. CLICK TO VIEW
