Temporal lobe epilepsy surgery: definition of candidacy

Medical intractability is one of the absolute indications for considering temporal lobe epilepsy surgery. This is a relative concept that has to be highly individualized. It is quite easy to determine when a patient's seizures are fully controlled. On the other hand, "continuing seizures are not necessarily a measure of intractability or disability". A positive decision to operate would be based on some of the following factors: assurance of a firm diagnosis, seizures that are frequent and disabling, and seizures occurring in patients who are drug refractory to optimal anti-epileptic medications and dosages.
