My son had an elementary school classmate who was born with only half her brain. I was friends with her mother (a single woman who adopted the baby as an infant through private adoption when she was in her mid 30s). It wasn't until the baby started missing the usual milestones that she and the pediatrician became aware something was amiss and tests were run to find the cause of the delays. The little girl needed every kind of therapy you could imagine. I lost contact with the woman years ago, but by the time the little girl was in 5th grade she had graduated from using a wheelchair to a walker to finally only needing a cane to walk. One side will always be weak, but because of intense physical therapy, she was able to build strength in the affected areas. Her cognitive skills were within the normal range, and she had some speech impediments. I pray the baby boy featured in the article does as well or better.
My husband has a cousin who suffered from seizures for years. Hers were more trance like. They were becoming more intense and frequent as she got older. As a young adult (early 20s) she had surgery to remove the small affected section of her brain at UVA medical center. She's in her 40s now, married, with a masters in education and is a PE teacher. She's 100% seizure free since the surgery. This was different in that only a small part of her brain was removed, but thankfully, after recovery, there were no adverse side affects whatsoever from her surgery.
