Question

Quizplus · Accepted Answer

The primary symptom of REM-sleep behavior disorder is the ability of a person to move during REM sleep, which is not typically seen in individuals without the disorder. This can result in the person acting out their dreams, potentially causing harm to themselves or others. Attacks of cataplexy are a symptom of narcolepsy, not REM-sleep behavior disorder. A depressed mood upon awakening could be a symptom of several sleep disorders, but it is not specific to REM-sleep behavior disorder. Motor movements during slow-wave sleep are a symptom of sleepwalking, not REM-sleep behavior disorder. Loss of dreams during REM sleep is not a symptom of any sleep disorder.
