Chapter 6: Parasomnias

Assessment and Diagnosis of Rapid Eye Movement Sleep Behavior Disorder (RBD)

Similar clinical assessment as is required of all parasomnias. Most parasomnias are diagnosed by detailed patient history and interview. Polysomnography (PSG) may be necessary to rule out other sleep disorders, particularly narcolepsy. The evaluation is often videotaped for better documentation and assessment.
