Electroencephalogram (EEG) Testing

An EEG test measures the electrical activity of the brain. During an EEG test, sensors attached to the patient’s scalp are hooked up to a computer to record the brain’s electrical activity. This may be done to study sleep disorders.

EEGs are used to diagnose or monitor seizures, epilepsy, brain diseases, confusions, fainting spells, memory loss, head injuries, infections, and tumors. EEGs are also used to evaluate sleep disorders.
