Has anyone heard of the books Brain Injury Rewiring for Survivors and Brain Injury Rewiring for Loved Ones?

I'm trying to help my son whose skull was fractured when he was a baby. As I read more about TBI, I wonder if he would be different than he is today if the accident hadn't have happened. He's even asked me that same question.

He has terrible headaches, dark horrible thoughts that he doesn't want to have and can't sleep without a sleeping pill.

Any ideas or suggestions?
