Narcolepsy with cataplexy is caused by the loss of a chemical in the brain called hypocretin. Hypocretin acts on the alerting systems in the brain, keeping us awake and regulating sleep wake cycles.
It is the cardinal symptom of narcolepsy with cataplexy affecting roughly 70% of people who have narcolepsy, and is caused by an autoimmune destruction of the neurotransmitter hypocretin, which regulates arousal and wakefulness. Cataplexy without narcolepsy is rare and the cause is unknown. The term cataplexy originates from the Greek ÎºÎ±ÏÎ¬ (kata, meaning down), and ÏÎ»á¿Î¾Î¹Ï (plÄxis, meaning stroke).
