What Is Narcolepsy?

Narcolepsy is a condition that causes extreme sleepiness during the day and sleep attacks that occur during waking hours. Symptoms include extreme drowsiness, auditory and visual hallucinations, sleep paralysis, and cataplexy.

There is no cure for narcolepsy. The key is to control symptoms. Common drug classes used to treat narcolepsy are central nervous system depressants, central nervous system stimulants, and sympathomimetic-like agents.
