Dr. Ilyas Munshi serves as a privately practicing neurosurgeon in Lafayette, Louisiana. Experienced in treating a comprehensive range of conditions of the brain and spinal cord, Dr. Ilyas Munshi maintains a particular focus on surgical treatment of epilepsy.

When a patient’s epilepsy indicates that surgery might be the most appropriate option, the surgeon takes into consideration the type of epilepsy when determining the procedure type. The majority of patients who undergo epilepsy surgery receive what surgeons call a resection, in which the surgeon removes the area of the brain responsible for the patient’s seizures. This is the form of epilepsy surgery with the highest success rate for reducing or stopping seizure activity.

Patients who do not undergo a resective surgery may instead be candidates for a disconnective procedure. Unlike a resection, which is potentially curative, these surgeries primarily aim to stop the spread of seizures and thus limit their severity.

The disconnective surgery may be helpful if a patient’s seizure activity takes place in multiple parts of the brain or in a part of the brain on which surgery is too risky. A corpus callosotomy, for example, enables the surgeon to cut off the nerve connections between the two halves of the brain, thus preventing inter-hemispheric seizure spread. Rarely, a surgeon will instead choose to perform a multiple subpial transection, which can provide some relief for frequent and severe seizures by making incisions into multiple relevant parts of the brain.
