If not treated, people with narcolepsy can fall asleep at any time, such as when at work, while driving and while engaged in a conversation. Narcolepsy is linked to a chemical in the brain called hypocretin, which normally stimulates arousal and helps regulate sleep. Most people with narcolepsy do not produce hypocretin in the deep part of the brain called the hypothalamus. As a result, the body's messages about when to sleep and when to stay awake sometimes occur at the wrong times and places.

Narcolepsy is a lifelong condition that affects an estimated one in 1,000 to 1,500 people. Although it occurs in both men and women, it is slightly more common among men. The condition can begin at any age, although its symptoms usually appear between the ages of 10 and 20. Narcolepsy has been found to be hereditary in some cases.
