Periodic oscillatory slowing and aperiodic broadband shifts in isolated REM sleep behavior disorder are associated with phenoconversion.
STUDY OBJECTIVES Conventional EEG slowing in isolated REM sleep behavior disorder (iRBD) may be confounded by disease-related shifts in the aperiodic background. We separated periodic and aperiodic EEG components to clarify oscillatory slowing and examine associations with phenoconversion and clinical measures. METHO...
