Autism Spectrum Disorders: Definitions
Who is at Greatest Risk of Autism?
Who is at greatest risk? The bottom line is that boys are at much higher risk than girls, and that boys from families in which at least one other person is autistic are at higher risk of autism. If one identical twin is autistic, his twin is extremely likely to also be autistic (though the autism may present quite differently).
