Abstract

REM sleep behavior disorder is parasomnia characterized by unpleasant dreams and dream-enactment behaviors associated with excessive electromyography activity in REM sleep. This may appear idiopathic or secondary to other neurological or medical conditions. REM sleep behavior disorder, which appears to be idiopathic, most often implies the possibility of later neurodegenerative diseases due to synucleinopathy, so accurate diagnosis is important in predicting prognosis. For the diagnosis of REM sleep behavioral disorder, REM sleep without atonia, which appears in the polysomnography, is essential. Obstructive sleep apnea, trauma-related sleep disorders, and vigorous periodic leg movements during sleep are known as diseases that show dream enactment behavior in elderly patients. Considering that it may be accompanied by other sleep disorders that can mimic REM sleep behavioral disorders, it is important to differentiate sleep Sleep Medicine and Psychophysiology 2022；29(2)：35-39
