REM Sleep Behavior Disorder: How Do We Decide if REM EMG Activity is Excessive?
NAPS Co-Principal Investigator Dr. Brad Boeve teams up with Dr. Mike Silber, a member of the NAPS Scientific Advisory Board, for an episode on REM sleep behavior disorder (RBD) in the Mayo Clinic Sleep Medicine Podcasts.
The diagnosis of REM sleep behavior disorder needs, in addition to dream enactment behavior, a determination that EMG activity is excessive during REM sleep. But what is excessive? In this podcast, the team discusses how a practicing polysomnographer can make this determination.
