Narcolepsy and Cataplexy

Narcolepsy is a chronic neurological disorder that causes persistent sleepiness and additional symptoms such as muscle weakness known as cataplexy, dreamlike hallucinations, vivid, brief episodes of paralysis when falling asleep or upon awakening and fragmented night time sleep. Narcolepsy usually begins between ages 10 and 20, although sometimes it starts as late as age 40 or 50. Narcolepsy affects women and men equally, occurring in about 1 in 2,000 people.

Cataplexy is a sudden loss of muscle tone that causes feelings of weakness and loss of voluntary muscle control. Cataplexy attacks generally last less than two minutes, and they may only last a few seconds to 30 minutes. About 75% of patients with narcolepsy experience cataplexy. Narcolepsy with cataplexy is a disabling sleep disorder affecting 0.02% of adults worldwide.
