Narcolepsy is a sleep disorder characterized by sudden episodes of deep sleep during the day, called "sleep attacks," and often triggered by emotional excitement. These episodes can cause a loss of muscle tone, called cataplexy, in which a person may collapse or experience temporary paralysis. Apnea is a sleep disorder in which a person's breathing is disrupted during sleep, and insomnia is a sleep disorder characterized by difficulty falling or staying asleep.
