Narcolepsy occurs because persons afflicted have REM sleep that occurs at the wrong times. This REM sleep is disturbed in order and length, thus robbing restful and proper sleep. There is no known cause of narcolepsy, and its symptoms cause those affected to fall asleep or not be able to move at strange times and places, even if they have had adequate nighttime sleep. This can happen at work, while driving, or in many other dangerous situations. Hallucinations, sleep paralysis, and losing muscle control and functions are also common symptoms. Recording brain waves, nerve and muscle functions while aslep is used to diagnose this condition. There is no cure for narcolepsy, but many treatments are available. Central nervous system stimulants and antidepressants are frequently prescribed. Short daytime naps and lifestyle changes are also used to help alleviate symptoms for this life-long condition that requires continuous treatment and monitoring. Research is being done to find out more on how to treat and control this disorder that is estimated to afflict more than 200,000 people in the U.S.
