One of the most dramatic surgical interventions in human patients is hemispherectomy, or the removal or deactivation of half of the brain. This is a last resort strategy often used to end major seizures. In 75 percent of patients, the seizures stop completely after the operation.

In rare cases, a hemispherectomy is required due to trauma. In 1987, Ohio, 14-year-old Ahad Israfil was accidentally shot in the right side of his head. Most of the right hemisphere was destroyed, but Israfil survived five hours of the operation and attempted to speak shortly after regaining consciousness. He remained in a wheelchair but graduated from college. He lived until October 18, 2019 when he died in a nursing home at the age of 47.
