What is Excessive Daytime Sleepiness (EDS)?

Excessive Daytime Sleepiness (EDS) is a neurological disorder in which there is a sudden uncontrollable urge to sleep. These attacks of sleepiness may occur often during the day or only occasionally, and episodes may be mild/ moderate or severe. Children complain that they feel tired all the time and fall asleep at unusual times. They may have vivid nightmares or sudden loss of muscle control and fall to the ground. It occurs in boys and girls equally, usually in their teens, and in people of all races.

What causes EDS?

The cause is unknown but is thought to be related to an abnormality in the brain that controls sleep and wakefulness. Occasionally more than only one family member may be affected.

How is EDS treated?

At present there is no cure, however behavior modification and various medications may be prescribed depending on which particular symptoms are present.
