Patient discussion about dysgenesis

Q. Is it a birth defect in children? I know about the causes of autism. Is it a birth defect in children?

A. it's not an easy answer i'm afraid...there are congenital differences, but no "birth defect" that we can detect. there's a good pdf file that gives a full explanation about it...i think you'll find it useful:
