Development

Other screening tools for RBD are lengthy and difficult to use for epidemiological studies, needed to determine the prevalence of RBD. Participants for a case-control study were recruited from twelve centers of the International REM Sleep Behavior Disorder Study Group between 2008 and 2011. The 484 participants (242 individuals with polysomnogram-confirmed RBD and 242 controls) completed the screen. Dream-enactment behavior was established by history or video recording, and the absence of
