Narcolepsy is a chronic neurological disorder caused by the brain's inability to regulate sleep-wake cycles normally. It often begins mildly and progresses over a period of time until it reaches full manifestation. People with narcolepsy often experience disturbed nocturnal sleep and an abnormal daytime sleep pattern, which often is confused with insomnia. Narcoleptics, when falling asleep, generally experience the REM stage of sleep within 5 minutes, while most people do not experience REM sleep until an hour or so later. REM sleep is where most dreams occur. One of the many problems that some narcoleptics experience is cataplexy, a sudden muscular weakness brought on by strong emotions. It often manifests as muscular weaknesses ranging from a barely perceptible slackening of the facial muscles to the dropping of the jaw or head, weakness at the knees, or a total collapse. Usually speech is slurred and vision is impaired, but hearing and awareness remain normal. In some rare cases, an individual's body becomes paralyzed and muscles become limp. Cataplexy also has a severe emotional impact on narcoleptics, as it can cause extreme anxiety, fear, and avoidance of people or situations that might elicit an attack. Some narcolepsy affected persons also experience heightened senses of taste and smell.
U.S. National Library of Medicine
A condition characterized by recurrent episodes of daytime somnolence and lapses in consciousness (microsomnias) that may be associated with automatic behaviors and AMNESIA. CATAPLEXY; SLEEP PARALYSIS, and hypnagogic HALLUCINATIONS frequently accompany narcolepsy. The pathophysiology of this disorder includes sleep-onset rapid eye movement (REM) sleep, which normally follows stage III or IV sleep. (From Neurology 1998 Feb;50(2 Suppl 1):S2-S7)
