Brain injuries can be life-changing. No matter the nature of the injury, when your brain is hurt, your healing process can be much different compared to any other body part because your brain controls your whole body. Some brain injuries are mild and are able to heal with minimal medical intervention, like minor concussions. But when a brain injury is severe and alters the way the brain functions, the result on that person’s life could be physically, emotionally, and financially catastrophic.
