In UNDERSTANDING AUTISM: My Quest for Nathan, I describe how my son was taken by autism leaving only a reflection of the child I knew. He still looked the same, but inside his mind was scrambled and he was like someone from a different world. Something had reversed his normal brain development. As I took him from doctor to doctor, it became clear to me that no one knew what caused his autism and there were no effective medical treatments. It was up to me to discover the answers for myself, and after 17 years of research, I am able to make sense of what autism is about. I know what causes autism, how to prevent it, and how to treat it. This book explains what I have discovered.
