Experts believe that narcolepsy is caused by reduced amounts of a protein called hypocretin, which is made in the brain. What causes the brain to produce less of this protein is unclear.

If a person has both excessive daytime sleepiness and cataplexy, narcolepsy can be diagnosed on the basis of patient history alone. Lab tests, however, can confirm a diagnosis. Tests at a sleep disorders clinic include an overnight polysomnogram (...

In 1999, researchers identified the gene that causes narcolepsy. The gene allows cells in the hypothalamus (the part of the brain that regulates sleep behavior) to receive messages from other cells. When this gene is abnormal, cells cannot communi...

In 1999 researchers identified the gene that causes narcolepsy on chromosome 12. The gene allows cells in the hypothalamus (the part of the brain that regulates sleep behavior) to receive messages from other cells. When this gene is abnormal, cell...
