Orthostatic hypotension and cardiac sympathetic denervation in Parkinson disease patients with REM sleep behavioral disorder

摘要

Background: Rapid eye movement (REM) sleep behavioral disorder (RBD), orthostatic hypotension (OH), and cardiac sympathetic denervation were commonly observed in PD and are related in both the premotor and motor periods. This study is intended to evaluate if the OH and cardiac sympathetic denervation found in PD are associated with RBD.
