Question 1

What is REM Sleep Behavior Disorder?

Accepted Answer

REM Sleep Behavior Disorder (RBD) is a parasomnia characterized by repeated episodes of vocalization and/or complex motor behaviors during REM sleep, often associated with dream enactment. These behaviors occur because the normal muscle atonia of REM sleep is absent, allowing the sleeper to physically act out their dreams.

Question 2

How is REM Sleep Behavior Disorder diagnosed?

Accepted Answer

A. Repeated episodes of arousal during sleep associated with vocalization and/or complex motor behaviors. B. These behaviors arise during REM sleep, typically more than 90 minutes after sleep onset, and are more frequent during later portions of the sleep period. C. Upon awakening, the individual is alert and not confused or disoriented. D. Either: polysomnographic recording demonstrates REM sleep without atonia, or a history suggestive of RBD and an established diagnosis of a synucleinopathy (e.g., Parkinson’s disease, multiple system atrophy, Lewy body dementia). E. The disturbance is not better explained by another sleep disorder, mental disorder, medication, or substance use.

Question 3

What treatments are available for REM Sleep Behavior Disorder?

Accepted Answer

Treatment for REM Sleep Behavior Disorder typically includes medications, lifestyle changes.

Question 4

Can REM Sleep Behavior Disorder be cured?

Accepted Answer

Chronic course if untreated. In many cases, RBD precedes the onset of neurodegenerative disease by years or decades. Symptom control is achievable with safety modifications and medication.
