Narcolepsy is a neurological condition most characterized by Excessive Daytime Sleepiness (EDS). A narcoleptic will most likely 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 any random time. Narcolepsy affects an estimated 25 in every 100,000 people in the United States. This sleep disorder is primarily characterized by intermittent, uncontrollable episodes of falling asleep during the daytime. Three additional symptoms are typically associated with narcolepsy: cataplexy (short-lived intermittent muscle weakness), hypnogogic and hypnopompic hallucinations (hallucinations while falling asleep or waking), and sleep paralysis (paralysis while falling asleep or waking). Narcolepsy usually begins when a person is in their teens or early twenties. Stimulants and antidepressants are used to treat narcolepsy and subsequent cataplexy. Although it has been linked with blood pressure management and depression, the genesis of narcolepsy is unknown. However, recent advances in narcolepsy study suggest the possibility of a cure.
