RBD in PSP Linked to Tau Pathology in Locus Coeruleus

RBD in PSP Linked to Tau Pathology in Locus Coeruleus

The study explores the prevalence of self-reported rapid eye movement sleep behavior disorder (RBD) in patients with progressive supranuclear palsy (PSP) and its clinical and imaging correlates. Of 148 patients, 18.2% reported RBD, with higher frequencies in PSP-Richardson syndrome and PSP-parkinsonism. These patients also exhibited more severe symptoms and greater tau deposition in the locus coeruleus, as shown by 18F-florzolotau PET. RBD frequency was linked to tau accumulation in the LC, highlighting the role of tau pathology in disrupting sleep regulation.
