Abstract

Methods and systems for diagnosing or assessing rapid eye movement sleep behavior disorder (RBD). Muscle tone or activity variance during rapid eye movement (REM) and nonrapid eye movement (NREM) sleep intervals of a polysom- nogram are compared. A threshold based on the NREM data is used to identify a subj ect-specific threshold for abnormality in the REM variance. A metric that includes the percentage of REM variance exceeding the threshold relates to RBD.
