Get to Know Narcolepsy

Narcolepsy symptoms are not always obvious.

Narcolepsy is a chronic, neurologic disorder. All people living with narcolepsy have excessive daytime sleepiness (EDS). Other symptoms, such as cataplexy, may also be present.

Narcolepsy symptoms can disrupt everyday life, but the impact isn’t always obvious.

Getting to know narcolepsy means recognizing the less obvious symptoms, understanding their impact, and finding ways to live better with narcolepsy.
