Epilepsy surgery

From Wikipedia, the free encyclopedia

Epilepsy surgery involves a neurosurgical procedure where an area of the brain involved in seizures is either resected, disconnected or stimulated. The goal is to eliminate seizures or significantly reduce seizure burden.

First line therapy for epilepsy involves treatment with antiepileptic medications. Most patients will respond to one or two different medication trials. The goal of this treatment is the elimination of seizures, since uncontrolled seizures carry significant risks, including injury and sudden death. However, in up to one third of patients with epilepsy, medications alone will be unable to eliminate seizures. In these patients, epilepsy surgery is considered.

Generally, surgery is considered in patients whose seizures cannot be controlled by adequate trials of two different medications. Epilepsy surgery has been performed for more than a century, but its use dramatically increased in the 1980s and '90s, reflecting its efficacy in selected patients.
