Sleep is absolutely essential for normal, healthy function. According to the National Institute of Neurological Disorders and Stroke, about 40 million people in the United States suffer from chronic, long-term sleep disorders, while an additional 20 million people suffer occasional sleep problems. There are more than 80 different sleep disorders that are generally classified into one of three categories:

In most cases, sleep disorders can be easily managed once they are properly diagnosed. Inadequate sleep can have severe detrimental effects on health. Studies have shown that sleep is essential for normal immune system function and to maintain the ability to function both mentally and physically. In addition, sleep is essential for learning and for normal, healthy cell growth.

The Sleep Disorders Center at Texas Neurology provides comprehensive evaluation and management of adult patients with sleep disorders. Working in tandem with your physician, our trained staff will monitor and record the data needed to make the proper diagnosis and suggest the appropriate treatment plan. In addition to sleep studies, our services include a weekly sleep clinic, that provides formal consultation, follow-up, and management of various sleep disorders.

To simulate the closest conditions to sleeping at home, our rooms are nicely appointed and resemble a comfortable suite at a fine hotel. At the same time, our center is equipped with advanced digital technology in polysomnographic recording where routine and airway pressure titration studies are performed, as well as multiple sleep latency tests.
