My 10 year old son has been diagnosed with Asperger's, Tourette's, and Vitiligo. His father did use drugs, and as a result, I was stressed during pregnancy. But, he also had a head injury when he was 7. He fell out of a tree, and was unconcious for some time. I could be wrong, but I always felt it was the head injury that did it. He is currently in play therapy, but I am not sure it is helping. He has severe tactile disturbances. I am a nurse, and I still find this difficult to understand.
