    Electroencephalogram (EEG)

    An electroencephalogram (EEG) is a procedure that measures the electrical impulses in the brain. An EEG is done by placing small sensors (electrodes) on a person's scalp to detect the electrical impulses moving through the brain.

    An EEG is often used to help determine the presence and cause of seizures. The amount and pattern of electrical activity is important in diagnosing seizure disorders.
