The Ephraim McDowell Sleep Disorders Center, accredited by the American Academy of Sleep Medicine, is uniquely qualified to diagnose and treat sleep disorders, which can have a debilitating effect on a person’s quality of life.  Our sleep specialist is qualified to work with patients as young as 4 years old through adulthood.

If you are likely to fall asleep while: reading a book, watching television, sitting in a theater or meeting, riding in a car for an hour without a break, lying down in the afternoon, sitting and talking, following lunch, or in a car while stopped in traffic, then the specialist at our sleep disorders center may be able to help you if you answered yes to three or more of the above.
