Narcolepsy is a chronic sleep disorder characterized by overwhelming daytime drowsiness and sudden attacks of sleep. People with narcolepsy often find it difficult to stay awake for long periods of time, regardless of the circumstances. Narcolepsy can cause serious disruptions in your daily routine.
The cause of narcolepsy isn't well understood but may involve genetic factors and abnormal signalling in the brain. Narcolepsy causes sudden attacks of sleep. Sudden loss of muscle tone and hallucinations might occur.
Stimulants, antidepressants and other medication can help.
