Center for Sleep Medicine

Mercy's Center for Sleep Medicine offers the latest technology in a comfortable, contemporary setting. Expert, board certified sleep physicians will diagnose and treat sleep disorders, with certified technologists monitoring patients’ sleep cycle during overnight sleep study tests in a hotel-like environment.

Sleep disorders can include conditions such as snoring and insomnia and potentially serious disorders such as sleep apnea and even restless leg syndrome. Men and women who have a sleep disorder often wake up not feeling refreshed and may experience daytime drowsiness or suffer from "brain fog," or confusion. Sleep disorders that go undiagnosed can cause problems with an individual’s daily routine and affect overall health. People with obstructive sleep apnea actually stop breathing for short periods of time and are likely to experience a wide range of health issues.
