Surgery is considered in up to 15 percent of individuals with epilepsy when treatment with various seizure medications does not result in an individual being seizure free.

Epilepsy surgery most commonly involves the removal of the part of the brain where the seizures originate. Less commonly, an operation is used to reduce the spread of a seizure from one side of the brain to the other. Like any surgical procedure, there are risks and potential benefits. Lengthy testing and evaluation by a team of health professionals is required before a decision to try this option can be made.
