title: Isolated cataplexy and REM sleep behavior disorder after pontine stroke.
abstract: Cataplexy is a complex neurologic phenomenon during wakefulness probably resulting from impairment of pontine and hypothalamic control over muscle tone. REM sleep behavior disorder (RSBD) is characterized by the presence of REM sleep without atonia manifesting clinically as disruptive or injurious behaviors. We present here a patient with both cataplexy and RSBD following pontine encephalomalacia. The clinical presentation provides insight into the possible pathobiology of both waking and sleeping disorders of REM sleep regulation.
