Who Is At Risk for Narcolepsy?
Narcolepsy affects between 50,000 and 2.4 million
people in the United States. 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. Narcolepsy affects both men and women.
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, see
