Sleep Apnea

    NORTHBROOK, IL, October 29, 2008 /24-7PressRelease/ -- Excessive daytime fatigue may be a sign of an ongoing problem with nighttime sleep known as sleep apnea - the repeated cessation of breathing. This sleep disorder is characterized by pauses in breathing lasting more than 10 seconds, and occurring at least five times per hour. Many people suffering from sleep apnea do not realize they have this problem unless told by an observer.

If left untreated this condition can alter heart rhythms, reduce oxygenation to the brain, and prevent the deep REM sleep necessary to recuperate from the day's activities. In some cases a deadly form of congestive heart failure may develop. Sleep apnea is diagnosed with an overnight sleep study called a polysomnogram.

Sleep Apnea Symptoms
• Headaches
• Insomnia
• Nasal congestion
• Daytime fatigue
• Snoring

Forms of sleep apnea

1. Obstructive sleep apnea - As the throat muscles relax during sleep, they may get in the way of normal breathing. Obesity increases the risk of developing sleep apnea, because of the extra tissue that can sag and block the airway. Older people and men are more likely to develop obstructive sleep apnea than younger people or women.

2. Central sleep apnea - This type is caused by a neurological problem. The signal to breath comes from the build up of carbon dioxide needing to be expelled from the blood. During this type of apnea, that trigger is skipped, and people don't breathe. There is no struggle, but no breathe comes. The period of apnea is followed by rapid, energetic breathing (hyperpnea) to expel the carbon dioxide. This is also known as Cheyne-Stokes respiration. This type of apnea requires significant medical intervention.

3. Complex sleep apnea - Also known as mixed sleep apnea, this form is a combination of both obstructive and complex apnea. After long periods of obstructive sleep apnea, central sleep apnea may develop.

Treatment options
Treatment includes:
• Lifestyle changes like avoiding muscle relaxers or alcohol, which increase muscle laxity
• Weight loss
• Smoking cessation
• Sleeping on one's side as opposed to the back.
• Continuous Positive Airway Pressure machines (CPAP) are common treatments.

Dentists who treat sleep disorders may prescribe Oral Appliance Therapy (OAT). This is a custom-made mouthpiece that moves the lower jaw forward, opening the airway. These appliances are most successful if the sleep apnea is mild to moderate.
