Narcolepsy is a neurological condition most characterized by Excessive Daytime Sleepiness (EDS), in which a person falls asleep during the day at inappropriate times, such as at work or school. A narcoleptic will most probably experience disturbed nocturnal sleep, which is often confused with insomnia, and disorder of REM or rapid eye movement sleep. It is one of the dyssomnias. A narcoleptic may also fall asleep at random.
The main characteristic of narcolepsy is excessive daytime sleepiness (EDS), even after adequate night time sleep. A person with narcolepsy is likely to become drowsy or fall asleep, often at inappropriate times and places. Daytime naps may occur without warning and may be physically irresistible. These naps can occur several times a day. They are typically refreshing, but only for a few hours. Drowsiness may persist for prolonged periods of time. In addition, night time sleep may be fragmented with frequent awakenings. Four other "classic" symptoms of narcolepsy, which may not occur in all patients, are cataplexy, sleep paralysis, hypnagogic hallucinations, and automatic behavior.
