Epilepsy is a disorder that manifests itself in the form of seizures by over- stimulation of cells that make up the brain as a result of temporary abnormal electrical spread. Patients display behavioral, emotional, movement or perception disorders such as loss of consciousness for a certain period of time, body convulsions, fainting, incontinence, shaking off arms and hands, etc.
Epilepsy is the most common neurological disease seen during childhood and puberty. Although it is seen in every age group, it affects the youngest and the oldest groups the most. Epilepsy mainly occurs as a result of genetic factors. In addition, head trauma, brain infections, vascular occlusion, tumors , and a number of hormonal disorders can also lead to the formation of epilepsy.
This disease requires a long-term treatment and significantly affects the quality of life. In majority of patients, seizures can be controlled with correct treatment and the patient resumes a normal life. However, in 25% of patients, despite the use of appropriate drugs, seizures can not be controlled. If epilepsy couldn't be controlled and drug treatment has failed, surgical methods are used.
There are two main types of epilepsy surgery method. The first and the one preferred is removal of the epileptic focus (resective surgery). The other is the surgical method for reducing spread, frequency and severity of seizures by cutting seizure propagation paths(functional surgery, palliative surgery). Resective surgery is mainly applied in resistant epilepsies in which medication therapy has been tried.
