A:The severity of a brain injury may impact one’s ability to heal from it, but unfortunately, there is no way for doctors to predict whether treatments will succeed. Because babies’ brains are so flexible, they may be able to shift the functions that would normally be handled by the damaged cells to those that have not been damaged. However, this is only sometimes possible and depends both on the breadth of the injury and individual patient factors. Many traumatic brain injury victims never fully recover.
