Hypersomnia, which refers to either excessive daytime sleepiness or excessive time spent sleeping, 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.

5 Steps for Stopping a Sleepwalker

Janice used to think her husband's sleepwalking was funny. He fumbled through the dark, often muttered incoherently, and occasionally walked into walls. But she stopped laughing when he made his way to the garage one night and started the car. Experts estimate that sleepwalking afflicts between 1% and 15% of the general population. It's more common in children -- especially those between the ages of 3 and 7 -- than in adults. According to the National Sleep Foundation's 2004 Sleep in America Poll,...

Causes of Hypersomnia

There are several potential causes of hypersomnia, including:

Diagnosing Hypersomnia

If you consistently feel drowsy during the day, talk to your doctor. In making a diagnosis of hypersomnia, your doctor will ask you about your sleeping habits, how much sleep you get at night, if you wake up at night, and whether you fall asleep during the day. Your doctor will also want to know if you are having any emotional problems or are taking any drugs that may be interfering with your sleep.

Your doctor may also order some tests, including blood tests, computed tomography (CT) scans, and a sleep test called polysomnography. In some cases, an additional electroencephalogram (EEG), which measures the electrical activity of the brain, is needed.

Treatment of Hypersomnia

If you are diagnosed with hypersomnia, your doctor can prescribe various drugs to treat it, including stimulants, antidepressants, as well as several newer medications (for example, Provigil and Xyrem).

If you are diagnosed with sleep apnea, your doctor may prescribe a treatment known as continuous positive airway pressure, or CPAP. With CPAP, you wear a mask over your nose while you are sleeping. A machine that delivers a continuous flow of air into the nostrils is hooked up to the mask. The pressure from air flowing into the nostrils helps keep the airways open.

If you are taking a medication that causes drowsiness, ask your doctor about changing to one that is less likely to make you sleepy. You may also want to go to bed earlier to try to get more sleep at night, and eliminate alcohol and caffeine.
