Gelastic syncope mistaken for cataplexy.
Laughter is a complex human behavior that has an emotional and a physical component. We present a patient who suffered syncope as a result of intense laughter, and hypothesize that this is analogous to other types of Valsalva-induced syncope. We emphasize the clinical characteristics that differentiate gelastic syncope from cataplexy.
