Causes, incidence, and risk factors Return to top The exact cause of narcolepsy is unknown. Studies have indicated that the disorder may be genetic, with studies showing gene markers that may indicate a tendency to develop narcolepsy. A small group of neurons in the brain has been implicated in producing transitions from sleep to wakefulness and vice-versa, and people with narcolepsy may have fewer of these neurons or they may have been damaged. The condition may be aggravated by conditions that cause insomnia , such as disruption of work schedules.

Narcolepsy Although people with the disorder do not fall face-first into their soup as in the movies, narcolepsy is still a mysterious disease. But science has new leads by Jerome M. Siegel SUBTOPICS: Sleep and Narcolepsy Narcoleptic Dogs An Autoimmune Disease? FURTHER INFORMATION We have found the first evidence of neuronal degeneration in narcolepsy. After hearing the punch line of the joke, the teenager falls to the floor, almost as if actually punched. She remains there, completely unable to move. She hears her parents reassure her friends that they need not worry about her because she will be all right in a few minutes. She is embarrassed and frustrated as the episode continues, and her friends begin to leave. They bid her goodbye, but she is unable to respond. Although she cannot talk or move, she is otherwise in a state of high alertness, feeling, hearing and remembering everything that is going on around her. The episode lasts for five minutes, longer than her typical cataplexieswhich often last only secondsbut shorter than her longest episode, which lasted 25 minutes. Then it ends, almost as abruptly as it began. She gets up from the floor, and her everyday life resumes. Cataplexy, the loss of skeletal muscle tone without loss of consciousness, is one of the defining symptoms of a puzzling neurological disorder called narcolepsy. The cataplectic attacks of narcolepsy are frequently prompted by laughter; other times, embarrassment, social interactions with strangers, sudden anger, athletic exertion or sexual intercourse may trigger an episode.

125. Recent Developments In Narcolepsy Research Our group at UCLA identified abnormalities in human brains that pinpoint the cause of most human narcolepsy. narcolepsy is no longer a mysterious disease. http://www.npi.ucla.edu/sleepresearch/xnarcnet.htm

Recent Developments in Narcolepsy Research, An Explanation for Patients and the General Public Jerome Siegel, UCLA, VA GLAHS Reprinted from the Narcolepsy Network Newsletter Winter, 2000 The cause of the death of the hypocretin cells is not entirely clear, but there are two possibilities. One is that a specific "poison" produced by the body or absorbed through the environment kills these cells. Parkinson's disease, another neurological disease caused by the loss of specific brain cells, can be triggered by ingested toxins, for instance. The second and more likely possibility is that the hypocretin cells are killed by the immune system, which confuses these cells with an infectious agent such as a virus. Other cells near where the hypocretin cells should have been appear to be normal; this indicates that whatever the cause of the cell loss, the hypocretin cells are targeted very specifically. What does finding the cause of narcolepsy mean for people with narcolepsy? This discovery ends the 120-year search for the cause of this debilitating disease. It also has important implications for people with narcolepsy: 1. We have clearly shown that narcolepsy is a neurological disease not a psychiatric one. The problem in not "in your mind," but rather is caused by damage to your brain, specifically to the hypothalamus. Many persons with narcolepsy have not only had to suffer from the disease but also from family members, friends and even physicians, who thought of narcolepsy as a motivational problem. Only the ignorant will now consider narcolepsy a psychological problem.

132. Health Report - 02/11/1998: Narcolepsy with Norman Swan narcolepsy Monday 2 November 1998. It s called narcolepsy, and despite its name, has nothing to do with epilepsy. http://www.abc.net.au/rn/talks/8.30/helthrpt/stories/s14093.htm

Radio National with Norman Swan Narcolepsy Monday 2 November 1998 Summary: This condition in its mildest form causes daytime sleepiness and at its worst can bring about a demi world of hallucinations, nightmares and periods of paralysis. Now to a condition that's probably under-recognised, which, in its mildest form, causes daytime sleepiness and at its worst, sentences the sufferer to a demi world of hallucinations, nightmares and periods of paralysis. It's called narcolepsy, and despite its name, has nothing to do with epilepsy. Narcolepsy's not that common, nor is it very rare, and I recently met with one of its leading authorities. He's Professor Michel Billiard who works at the oldest continually operating medical school in the world. It's at the University of Montpellier in the south of France. Montpellier also has one of the world's first sleep laboratories, which dates a bit more recently than the 14th century former monastery where I spoke to Professor Billiard about narcolepsy. Michel Billiard: It's actually a very strange condition because the people who are afflicted with narcolepsy fall asleep several times during the day.
