What is Cataplexy?

Cataplexy is a medical condition that causes a sudden or unexpected weakness in the muscle that is triggered by emotions such as excitement, sadness or anger. The attack of the disorder might lasts for few seconds to a couple of minutes that results in jaw dropping, weakness in the neck and buckling of the knees. Approximately 70% of the people who are suffering from narcolepsy are likely to experience cataplexy which is caused by the autoimmune disease that destroys the neurons which are responsible for the production of neuropeptides hypocretin (Orexin) that works in regulating the wakefulness to a person. There are no reports on the occurrence of cataplexy without narcolepsy in people.
