Which drug class is commonly used to treat REM sleep behavior disorder?

• A. Benzodiazepines
• B. Antidepressants
• C. Stimulants
• D. Antipsychotics

Answer: (A)

Benzodiazepines are commonly used to treat REM sleep behavior disorder because they boost GABAergic inhibition in the brain regions that control muscle tone during REM sleep. This enhances REM atonia, which normally prevents movement, and reduces dream-enactment behaviors. Clonazepam is the classic first-line agent in this class and has a long history of effectiveness in calming these nocturnal activities. While melatonin is sometimes used as an adjunct or alternative, the benzodiazepine class remains the standard pharmacologic option due to its reliable impact on REM-related motor activity. Antidepressants, stimulants, and antipsychotics do not reliably treat RBD and can sometimes worsen symptoms or cause other side effects, so they are not the preferred choices for this condition.
