More than 100,000 Americans have excessive daytime sleepiness (narcolepsy). It strikes both males and females and affects people of all races.
The symptoms most commonly appear in a person's teens and early twenties. The disease can vary in severity. Some persons with it have mild sleepiness or rare cataplexy (less than one episode per week). Other persons may have moderate sleepiness or infrequent cataplexy (less than one episode a day). Still other persons with the disorder may experience severe sleepiness or have severe cataplexy (with one or more episodes of cataplexy per day).
The basic cause of narcolepsy is not known. It is not a fatal disorder in itself but it can lead to fatalities. For example, a narcoleptic may fall asleep while driving.
Narcolepsy is usually treated with a medication to improve alertness and an anti-depressant that helps control cataplexy. The US Food and Drug Administration (the FDA) in 1998 approved Provigil (modafinil), a non-amphetamine drug for treating the excessive sleepiness of narcolepsy.
Other names for the condition include hypnolepsy, sleeping disease, paroxysmal sleep, and Gelineau syndrome.
