title: Asperger syndrome in 23 Swedish children.
abstract: Twenty-three Swedish children aged five to 18 years who fulfilled specific criteria for Asperger syndrome were examined and compared with an age- and IQ-matched group with infantile autism. The boy:girl ratio was 10:1. Less than 10 per cent were mentally retarded and 17 per cent were of above-average intelligence. Apart from motor clumsiness (very common in the Asperger group) and reduced optimality in the prenatal and perinatal periods (more common in the autistic group), there was very little in the clinical or neurobiological backgrounds to suggest a clear distinction between Asperger syndrome and infantile autism.
