This information was obtained through the LinguiSystems catalog. It was adapted from “The Source for Asperger’s Syndrome” by Timothy Kowalski. I cannot verify accuracy as there is a range, but it does make for some good comparing and contrasting of diagnoses.
A child with Asperger’s Syndrome typically has an IQ within the normal range. That said, the 2 most brilliant children I have ever worked with (both with IQ scores over 140) both had diagnoses of Asperger’s Syndrome. Because they seem to be developing typically at an early age (gross motor, fine motor, speech), most children with Asperger’s Syndrome are not diagnosed until after 3 years of age. Children with Asperger’s have obsessive interests, for example, they may only want to read and talk about: airplanes, dinosaurs, science facts, science fiction. The diagnosis is 5 times more common in boys than girls.
