The Northwestern Medicine Valley West Hospital Sleep Health Center conduct sleep studies to diagnose a variety of disorders in adults. Sleep studies are performed overnight using advanced computerized equipment to monitor the brain as it transitions through the stages of sleep and measure the functions of the lungs, heart, and other parts of the body.

The Northwestern Medicine Valley West Hospital Sleep Health Center can diagnose and treat numerous sleep disorders, including sleep apnea, periodic limb movement disorder, nocturnal behaviors (sleep walking, talking and eating in sleep, acting out dreams) disorders and narcolepsy.

Our centers are staffed by neurology and pulmonary critical care physicians, board-certified or board-eligible sleep medicine specialists, registered polysomnographic technologists, respiratory therapists specially trained in sleep disorders.
