	Narcolepsy - Wikipedia, the free encyclopedia
		Narcolepsy is a neurological condition most characterized by Excessive Daytime Sleepiness (EDS), episodes of sleep and disorder of REM or rapid eye movement sleep.
		Narcolepsy is strongly associated with HLA DQB1*0602 genotype.
		Narcolepsy is often mistaken for depression, epilepsy, or the side effects of medications.

	Narcolepsy Fact Sheet: National Institute of Neurological Disorders and Stroke (NINDS)
		Narcolepsy is a chronic neurological disorder caused by the brain's inability to regulate sleep-wake cycles normally.
		Scientists studying narcolepsy in dogs have identified a mutation in a gene on chromosome 12 that appears to contribute to the disorder.
		Except in rare cases, narcolepsy in humans is not associated with mutations of the hypocretin gene.

	Narcolepsy
		Narcolepsy is a sleep disorder associated with uncontrollable sleepiness and frequent daytime sleeping.
		Narcolepsy is characterized by episodes of frequent, uncontrollable daytime sleeping, usually preceded by drowsiness.
		Narcolepsy may also be associated with cataplexy, a brief episode of severe loss of tone of various muscles.

	National Sleep Foundation
		Narcolepsy is a neurological disorder caused by the brain's inability to regulate sleep-wake cycles normally.
		Narcolepsy affects both sexes equally and develops with age; symptoms usually first develop in adolescence or young adulthood and may remain unrecognized as they gradually develop.
		Narcolepsy patients typically endure many years of daytime sleepiness before seeking treatment because sleepiness is not indicative of disease to most people.

		Narcolepsy is a disorder marked by excessive daytime sleepiness, uncontrollable sleep attacks, and cataplexy (a sudden loss of muscle tone, usually lasting up to half an hour).
		Narcolepsy is related to the deep, dreaming part of sleep known as rapid eye movement (REM) sleep.
		Narcolepsy is a complex disorder, and it is often misdiagnosed.

	[No title]
		Narcolepsy is a chronic, incurable central nervous system disorder characterized by excessive and overwhelming daytime sleepiness, frequent sleep attacks, cataplexy, and abnormal REM (rapid eye movement, a sleeping state in which dreaming occurs) latency.
		Narcolepsy can be difficult to diagnose since many of its symptoms often overlap or are very similar with clinical features of other disorders.
		Neurochemical and electrophysiological studies have shown that narcolepsy is associated with an abnormal cholinergic supersensitivity and a monoaminergic (dopamine and norepinephrine) hypoactivity.

	Narcolepsy
		Narcolepsy is a genetic disorder, but what causes narcolepsy is not yet known.
		A person with narcolepsy is likely to become drowsy or to fall asleep at inappropriate times and places, and sleep attacks may occur with or without warning.
		The goal of treatment of narcolepsy is for the patient to remain as alert as possible during the day and to minimize any recurring episodes of cataplexy, while using a minimal amount of medication.

	Scientific American: Feature Article: Narcolepsy: January 2000
		The overall incidence of narcolepsy in the U.S. is about 10 times that of amyotrophic lateral sclerosis (Lou Gehrig's disease), half that of multiple sclerosis, five times that of cystic fibrosis and about one quarter that of Parkinson's disease.
		For some reason, in narcolepsy a group of neurons that is supposed to be active only during REM sleep to suppress muscle tone and protect us from the elaborate motor programs that accompany our dreams is being triggered during waking [see box].
		The degeneration in the dogs was most pronounced in the amygdala, a brain structure known to be involved in emotion and in inducing sleep, and adjacent regions at the bottom of the forebrain.

		Narcolepsy is a sleep disorder marked by recurring, uncontrollable episodes of sleep during normal waking hours, as well as by sudden episodes of muscle weakness (cataplexy), sleep paralysis, and hallucinations.
		Although narcolepsy has no serious medical consequences, it can be disabling and may increase the risk of motor vehicle and other accidents.

	Center for Narcolepsy - Stanford University School of Medicine
		Narcolepsy is a serious medical disorder and a key to understanding other sleep disorders.
		The Stanford Center for Narcolepsy was established in the 1980s as part of the Department of Psychiatry and Behavioral Sciences.
		The Stanford Center for Narcolepsy was the first to report that narcolepsy-cataplexy is caused by hypocretin (orexin) abnormalities in both animal models and humans (see FAQ and publications).

	Narcolepsy
		Narcolepsy is chronic, which means signs and symptoms may vary in severity, but they never go away entirely.
		These low levels of hypocretin may even lead to the development of a diagnostic test for narcolepsy because hypocretin is normally present in spinal fluid of people without the disorder, but often isn't found in the spinal fluid of people with narcolepsy.
		Narcolepsy affects males and females equally and occurs in all racial and ethnic groups.

	Narcolepsy Information Page: National Institute of Neurological Disorders and Stroke (NINDS)
		In addition to excessive daytime sleepiness (EDS), three other major symptoms frequently characterize narcolepsy: cataplexy, or the sudden loss of voluntary muscle tone; vivid hallucinations during sleep onset or upon awakening; and brief episodes of total paralysis at the beginning or end of sleep.
		It is likely that narcolepsy involves multiple factors interacting to cause neurological dysfunction and sleep disturbances.
		Among the most important common-sense measures people with narcolepsy can take to enhance sleep quality are actions such as maintaining a regular sleep schedule, and avoiding alcohol and caffeine-containing beverages before bedtime.

	Narcolepsy
		Many patients with narcolepsy experience periodic limb movement disorder, also called PLMD (formerly known as nocturnal myoclonus), in which the leg muscles involuntarily contract every 20 to 40 seconds during sleep, occasionally arousing the patient, who, however, is usually unaware of the cause of the interruption.
