What does it mean if i have been clinically diagnosed with narcolepsy?

Narcolepsy: Narcolepsy is a neurological diagnosis based on the patient's history, a polysomnogram, multiple sleep latency test (MSLT), and the Epworth Sleepiness Scale. It's a chronic brain disorder that involves poor control of sleep-wake cycles that results in sleep attacks. See your neurologist for further discussion. http://www.ninds.nih.gov/disorders/narcolepsy/detail_narcolepsy.htm
