‘I don’t have seizures anymore!’ 11-year-old Indiana boy with severe epilepsy undergoes rare operation to disconnect two sides of his brain.

In Zach’s case, his neurologist and epileptologist, Dr. Julia Henry, realized the changing and increasing medications no longer appeared to be helping him, and his condition was getting worse, with dozens of seizures a day. While in many cases the cause of seizures is uncertain, in Zach’s case it was clear that it was caused by the damaged portion of his brain, which made him a good candidate for surgery.
