Do children with autism have a bigger shaped head?

I am researching autism in children under 3 right now. My friend and I have been discussing my son. We believe, my son is showing signs of autism. My friend said he has autistic children in his family and those children have big heads. Like rounder in the back of the head. Does anyone know if this is typical in autism?

No it is not. Autistic kids come in all shapes and sizes.If your friend is worried they should see a medical practitioner.

Concur with above author. Autism isn't associated with any abnormality in skull shape. Other disorders do have some classic associations, but not autism.

It's typical of autism. http://www.sciencedaily.com/releases/2007/12/071208092451.htm In fact, all children who suffer severe stress in early infancy--premature birth, caesarean birth, surgery or severe illness shortly after birth, etc-- experience rapid neuronal overgrowth. The big exception is a supposed form of autism called "Rett Syndrome" where one of the symptoms is microcephaly. http://en.wikipedia.org/wiki/Rett_syndrome
