What Is Narcolepsy?

If excessive daytime sleepiness is disrupting your personal or professional life, or if you feel extremely tired all the time and often find it difficult to stay awake for long periods, a condition called narcolepsy may be the culprit. It's characterized by overwhelming daytime drowsiness and sudden attacks of sleep. Other symptoms may include sudden loss of muscle tone and sometimes hallucinations. Medications and lifestyle changes can help manage symptoms of narcolepsy. Dr. Roshini Raj explains.
