Epilepsy surgery removes or disconnects the specific area of the brain responsible for generating seizures in patients whose epilepsy is not controlled by medication. Through careful pre-surgical evaluation and mapping, neurosurgeons can target the seizure focus while minimizing impact on brain function, offering many patients significant seizure reduction or freedom from seizures.
Epilepsy surgery is considered when seizures continue despite trials of two or more appropriate medications, and when detailed evaluation (EEG monitoring, MRI, and other tests) identifies a clear, safely operable seizure focus in the brain.
