Epilepsy surgery is indicated as soon as possible in children who have drug-resistant epilepsy (DRE).
However, not every child with DRE is a candidate for surgery. The abnormal focus in the brain that causes the epileptic seizures must be well defined to be surgically removed. Moreover, the focus should not be located in areas that are too sensitive. In such cases, removal of the epilepsy focus can impair other neurologic functions (e.g language skills in left temporal lobe surgery).
