Learn about some of the tests performed at the Regional Epilepsy Center:


Electroencephalography, or EEG, is a procedure that uses electrodes placed along the scalp to measure electrical activity in the brain. It is an essential tool in the diagnosis and treatment of seizures.


Neuroimaging procedures, especially MRI (Magnetic Resonance Imaging) techniques, create detailed images of the brain that allow physicians to detect structural abnormalities that cause seizure disorders.

The Wada Test

The Wada test determines on which side of the brain speech, memory, and motor functions reside. It is used only on patients who are candidates for epilepsy surgery.
