Excerpt

Narcolepsy is a disorder of rapid onset rapid eye movement (REM) sleep characterized by excessive daytime sleepiness (EDS), frequent uncontrollable sleep attacks as well as sleep fragmentation and can be associated with cataplexy, sleep paralysis, and hypnagogic hallucinations. There are two types: narcolepsy type 1 (formerly narcolepsy with cataplexy) and narcolepsy type 2 (formerly narcolepsy without cataplexy).

The condition is often under-diagnosed and delays of 5-10 years are common before making a firm diagnosis. Close to 50% of patients develop symptoms in their teenage years. The disorder has enormous morbidity leading to impairment in academic and social performance. The condition, fortunately, does respond to treatment.
