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.
Persistent daytime sleepiness occurs in all people with narcolepsy. Narcolepsy can also cause cataplexy, brief episodes of muscle weakness triggered by strong emotions. In addition, narcolepsy can cause fragmented sleep with vivid dreams, and hallucinations and brief paralysis when dozing off or waking up. These symptoms typically begin between ages 10 and 20.
