EEG Monitoring

An electroencephalogram (EEG) is a safe and painless test that measures and records the electrical activity of the brain by using sensors (electrodes) attached to the head and connected by wires to a computer. The computer records the brain's electrical activity on the screen or on paper as wavy lines. Certain conditions, such as seizures, can be detected by observing changes in the normal pattern of the brain's electrical activity.

At Yale-New Haven, EEG testing can be done in an outpatient setting or during a hospital admission to diagnose and localize the affected area of the brain, and tailor care for each patient. Our six-bed inpatient monitoring unit is supervised by full-time neurologists who specialize in epilepsy.
