Cataplexy

Common Name(s)

Cataplexy

Cataplexy is a symptom shown only in people with narcolepsy. Cataplexy is a sudden loss of muscle tone while awake that makes you unable to move. Strong emotions, such as laughter or anger, can trigger this. Most attacks last for less than 30 seconds and can be missed. Your head will suddenly fall forward, your jaw will become slack, and your knees will buckle. In severe cases, a person may fall and stay paralyzed for as long as several minutes.
