Antidepressants Increase REM Sleep Muscle Tone in Patients with and without REM Sleep Behavior Disorder.

Study Objectives: REM sleep behavior disorder (RBD) is associated with antidepressant treatment, especially in younger patients; but quantitative REM sleep without atonia (RSWA) analyses of psychiatric RBD patients remain limited. We analyzed RSWA in adults receiving antidepressants, with and without RBD.

Design: We comparatively analyzed visual, manual, and automated RSWA between RBD and control groups.
