REM Sleep Behavior Disorder

Diagnosis

With accurate diagnosis, most sleep disorders can be effectively treated. All three Mayo Clinic locations operate sophisticated sleep centers staffed by experienced specialists.

Because REM sleep behavior disorder can be confused and/or coexist with other sleep disorders, an accurate, comprehensive diagnosis is important. In addition to a physical exam, a neurologic exam and complete medical history (use or withdrawal from certain drugs can cause REM sleep behavior disorder), an overnight sleep study is usually necessary to more fully understand the problem.

A sleep study (polysomnogram) is a painless test in which sensors are applied to the skin's surface to record brain wave activity, eye movements, breathing function, oxygen levels, heart rate and muscle activity during sleep. The patient is also simultaneously videotaped to document behavior during REM sleep cycles.

Reports by a bed partner are also helpful in diagnosis.
