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
