As a neurosurgeon at Cleveland Clinic Florida, Dr. Badih Adada focuses much of his practice on therapeutic surgeries for epilepsy. Dr. Badih Adada has served on the board of the Florida Epilepsy Foundation and stands out as the former director of the movement disorder and epilepsy surgery program at the University of Arkansas for Medical Sciences.

The indications of surgery as a treatment for epilepsy depend on the type of seizures and the region of the brain in which they develop. Most patients who receive epilepsy surgery undergo a resection procedure, or the removal of the area of the brain that causes the seizures. In the majority of cases, this tissue comes from the brain’s temporal lobe.

In a few cases, however, circumstances may indicate that removal of an entire neural hemisphere as the best option for controlling seizures. This procedure is typically indicated only for children under 13 with a malfunctioning hemisphere. There are also certain patients who require only removal of a tumor or other defect. In these patients, seizures most often cease following the removal of the lesion.

Some instances of epilepsy, by contrast, are most effectively treated through the surgical interruption of neural pathways that cause the spreading of seizures. For example, when seizures originate in an area of the brain that is critical for functioning, surgeons may choose to perform multiple subpial transections to interrupt seizure-causing impulses. Other situations may indicate the need for corpus callostomy, which involves the cutting of the nerve fibers that connect the two sides of the brain to stop the crossing over of seizure impulses. A complete examination by a surgeon is necessary to determine which, if any, of these procedures could address a particular patient’s seizure disorder.
