Kathryn, I have a child with Asperger's and suspect that another one of my children does as well. I believe it is genetically linked for sure. That MAY not be the only cause but I do feel it is genetically passed down. (My husband probably has Asperger's as well.)----I very, very much need to find other mothers who have children with Asperger's. I want to find a support group.--If you would like to communicate about all of it please e-mail me. I'm unlikely to return to this site soon and am having some internet/computer struggles so I may be slow to respond but e-mail's the best bet.
