Learn how to confirm a diagnosis of narcolepsy/cataplexy.

Narcolepsy is a condition of excessive daytime sleepiness, and the intrusion of REM sleep behaviors during waking hours (e.g. cataplexy, hypnagogic hallucinations, and sleep paralysis).


Narcoplepsy is typically confirmed with a Multiple Sleep Latency Test, with a sleep latency (i.e. sleep onset) less than 5 minutes and REM sleep beginning within 20 minutes.
