The US Centers for Disease Control and Prevention (CDC) considers sleep insufficiency a major public health problem. People nodding off while performing daily tasks has been linked to motor vehicle crashes, medical errors and industrial disasters. People who do not get sufficient sleep are more likely to suffer from chronic diseases such as high blood pressure (hypertension), diabetes, depression and obesity, as well as cancer, increased mortality, and reduced quality of life and productivity. Insomnia and obstructive sleep apnea are two major culprits, according to the CDC. Between 50 and 70 million US adults are believed to have a sleep or wakefulness disorder.

Getting Evaluated for a Sleep Disorder

If you are having trouble getting restful sleep, the Sleep Disorders Center at Northwest Texas Healthcare System can help. Our physicians focus on diagnosing and treating sleep disorders, such as sleep apnea, insomnia and other conditions. In many cases, after an initial consultation, you will be asked to stay overnight at the sleep center to help physicians diagnose your condition and recommend a plan of treatment. During the overnight stay, clinicians monitor sleep patterns, heart rate, breathing, muscle movement, brain waves and oxygen levels.

Each of the sleep study rooms includes a queen size bed with comfortable linens, television, bath towels, robe, bathroom and shower. Beverages and recliners are available upon request. We also have rooms that are ADA (Accessible).

Types of Sleep Disorders

The Sleep Disorders Center at Northwest Texas Healthcare System provides sleep studies to test for a variety of sleep disorders, including:


Insomnia (difficulty getting to sleep or staying asleep) may have numerous causes; there is often no one reason for insomnia. It may be caused by psychiatric conditions, medical conditions, unhealthy sleep habits, ingested substances (caffeine, alcohol, nicotine, medications), biological factors or some combination of these. Medications, such as those for colds and allergies, asthma, hypertension, heart disease, thyroid disease or depression are well known for contributing to sleep difficulties.

Sleep Apnea

Obstructive sleep apnea is a condition in which the soft tissue in the back of the throat collapses in the airway as a person sleeps. This causes the person to stop breathing, often hundreds of times each night. Symptoms include loud snoring followed by a sudden silence when breathing stops and gasping and snorting when breathing resumes. Left untreated, sleep apnea can lead to high blood pressure, heart failure, stroke, diabetes and more.

Restless Legs Syndrome

Restless legs syndrome (RLS) is characterized by an unpleasant sensation in the legs and the powerful urge to move them. Symptoms primarily occur at night, which can cause restless sleep and excessive tiredness during the day.


Narcolepsy is associated with extreme daytime drowsiness, as well as intermittent and involuntary sleep episodes that can occur during any daytime activity. Symptoms may include excessive sleepiness, hallucinations, sleep paralysis and a sudden loss of muscle tone that can cause slurred speech and muscle collapse.

Other Sleep Disorders

Our physicians can also evaluate and treat other disorders.
