About Narcolepsy
Narcolepsy is a chronic neurological disorder that affects the brain's ability to control sleep-wake cycles, causing excessive daytime sleepiness and sudden loss of muscle tone (cataplexy). It is caused by a deficiency of the brain chemical hypocretin. Treatment includes stimulant medications and sodium oxybate.
