Electroencephalogram (EEG)

What is an EEG?

An EEG is a test that is used to detect abnormalities in the electrical activities of your brain. Many electrodes, small metal discs attached to wires, are placed on your scalp to detect electrical charges from your brain activity. In order to analyze these electrical charges, the computer converts them into a graph which is then interpreted by a healthcare provider.

What is the purpose of an EEG?

The EEG can be recommended by your healthcare provider for many reasons. It may be used to evaluate or diagnose brain disorders.
