An electroencephalogram (EEG) records electrical activity in different areas of the brain. Your doctor may recommend EEG testing to help determine the cause of a sleep disorder, seizures, dementia or other neurological conditions.

EEG testing at Adventist GlenOaks Hospital can be scheduled Monday through Saturday, with limited appointments available on Saturdays. Call (630) 545-OAKS (6257) to schedule.

Overnight sleep studies are available through Adventist Midwest Health.
