There are three main components to the evaluation of children who are candidates for epilepsy surgery: (1) confirmation of the epileptic nature of the seizures, (2) establishing the medical intractability of the child's epilepsy and (3) localization of the epileptogenic zone. Differentiating epileptic from nonepileptic events requires careful review of the history and the electroencephalogram. Electroencephalographic recording of the habitual seizures usually suffices to confirm the epileptic or nonepileptic nature of the events. Medical intractability is established by assuring that antiepileptic medications appropriate for the child's particular epilepsy syndrome have been used and have been titrated to maximum tolerance before being deemed ineffective. Confident localization of the epileptogenic zone requires that multiple findings such as behavior during the seizure, ictal and interictal EEG, and cerebral imaging studies provide data that are convergent with respect to a likely area of seizure onset.
