Overview

Narcolepsy is a sleep disorder that causes episodes of extreme daytime sleepiness. 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 sleep paralysis. The disorder is estimated to affect about one in every 2,000 Americans. Most cases of narcolepsy are sporadic, which means that the condition occurs in one person in a family and is not inherited. However, up to 10 percent of individuals with narcolepsy have a close relative with the same symptoms. Other factors may be involved in causing narcolepsy, such as infection, immune-system dysfunction, trauma, hormonal changes, stress.[1]
