Sleep Disorders:

Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) is a common problem that affects a person’s breathing during sleep. A person with OSA has times during sleep in which air cannot flow normally into the lungs. The block in airflow (obstruction) is usually caused by the collapse of the soft tissues in the back of the throat (upper airway) and tongue during sleep. For more information on OSA click here.


Many people experience difficulty sleeping. Some people have short periods (days to a few weeks) of difficulty falling asleep or staying asleep (called acute insomnia). Others have this difficulty for a month or longer (called chronic insomnia). About 30% of Americans complain of having insomnia. Insomnia can be very disruptive to a person’s life, so understanding insomnia and what can be done to treat it can be helpful to your quality of life. For more information on insomnia click here.


Narcolepsy is a neurologic problem in which your brain is not able to control your sleep-wake cycle. It can cause you to have sudden and overwhelming sleepiness any time of the day. This can cause you to fall asleep at inappropriate times, such as while talking to someone, driving a car, eating, or while at school or work. This can at times put you in danger such as when driving. Narcolepsy is a lifelong condition that never goes away. About 1 in 2,000 people have narcolepsy. It affects men and women equally. Most people with narcolepsy will begin to have symptoms between the ages of 10 and 30 years old. For more information on Narcolepsy click here.
