narcolepsy« Back to Glossary Index
Narcolepsy is a chronic neurological disorder that affects the brain’s ability to control sleep and wakefulness. The most typical symptoms are excessive daytime sleepiness, cataplexy, sleep paralysis, and hypnagogic or hypnopompic hallucinations. Additional symptoms of narcolepsy include fragmented sleep and insomnia, and automatic behaviors. Unlike people with IH, people with narcolepsy generally feel refreshed after taking a nap. There are two types of narcolepsy – type 1 narcolepsy (in which a person either has low levels of a brain hormone [hypocretin] or has cataplexy), and type 2 narcolepsy (in which a person does not have cataplexy or low hypocretin).
