Sleep Disorders - Tests Can Detect Trouble

A polysomnogram is the name for the sleep study used to untangle the mystery of troubled sleep. For a sound study, patients generally spend one or two nights at the center.

Tiny electrodes are attached to record sleepstages, brain activity, heart activity and blood-oxygen levels. Completed test results are then used by the sleep physician for diagnosis and proper treatment.

Most sleep studies are covered by medical insurance. Patients are advised to consult with their insurance agency before undergoing studies.
