Abstract

Rapid eye movement (REM) sleep behavior disorder (RBD) is diagnosed based on a history of dream-enactment behavior and documentation of REM sleep without atonia (RWA) on polysomnography (PSG). RWA can be quantified using various methods. To establish comprehensive and clear PSG criteria for diagnosing RBD, the International RBD Study Group (IRBDSG) has recently published guidelines, which include the use of a video-PSG technical setup, REM sleep staging, RWA scoring, video and audio recording and analyses, and a video-PSG procedure for the diagnosis and identification of the prodromal stages of neurodegenerative diseases. Although the guidelines can identify patients with homogeneous RBD, their applicability in a real-world setting, particularly in Korea, presents challenges. Therefore, the aim of the present study was to evaluate and introduce IRBDSG guidelines and results of Korean sleep experts’ opinion survey for diagnosing RBD based on PSG findings.
