Questionnaire is a valid screening tool for RBD in older adults, study reports

A study in the May 15 issue of the Journal of Clinical Sleep Medicine evaluated the Mayo Sleep Questionnaire (MSQ) to screen for REM sleep behavior disorder (RBD) in older adults.  The responses of subjects’ bed partners were compared with the findings of polysomnography.  Results suggest that the MSQ has adequate sensitivity and specificity for the diagnosis of RBD among the elderly.
