What Are the Symptoms of Narcolepsy?

There’s more to narcolepsy than excessive daytime sleepiness.

All people living with narcolepsy have excessive daytime sleepiness (EDS), but they may not have the other 4 symptoms. People with cataplexy have type 1 narcolepsy; narcolepsy without cataplexy is often called type 2 narcolepsy.
