Sleep Disorders: Hypersomnia
Introduction to Hypersomnia
Comment on this
Hypersomnia, or excessive sleepiness, is a condition in which a person has trouble staying awake during the day. People who have hypersomnia can fall asleep at any time; for instance, at work or while they are driving. They may also have other sleep-related problems, including a lack of energy and trouble thinking clearly. According to the National Sleep Foundation, up to 40% of people have some symptoms of hypersomnia from time to time. © 2005-2013 WebMD, LLC. All rights reserved.
