Narcolepsy affects men and women. Symptoms usually begin during the teen or young adult years. The disorder also can develop later in life or in children, but it's rare before age 5.
Researchers think that certain factors may work together to cause narcolepsy. If these factors affect you, you may be at higher risk for the disorder. (For more information, go to "What Causes Narcolepsy?")

Dr. Michael Twery, director of the National Center on Sleep Disorders Research in the NHLBI's Division of Lung Diseases, interviews Dr. Emmanuel Mignot, director of the Stanford Center for Sleep Sciences and Medicine and the Stanford Center for Narcolepsy, about advances in narcolepsy research.
An NHLBI grantee, Dr. Mignot is credited with discovering the cause of narcolepsy—a disorder that causes periods of extreme daytime sleepiness. There is no known cure, but the NHLBI is committed to supporting research to better understand, treat, and even prevent or cure narcolepsy as well as other heart, lung, blood, and sleep disorders.
