Cognitive, behavior and intervention outcome in young children with autism.
UNLABELLED The relations between cognition and autism severity , head size and intervention outcome , were examined . Change in cognitive level with intervention was measured in children with autism and compared to children with developmental disabilities ( DD ) . Eighty-one children ( mean age 25.9 months ) with autism ( n=44 ) and DD ( n=37 ) were assessed at pre- and post 1 year of intervention . Cognitive abilities and autism severity were measured by st and ardized tests . Three pre-intervention cognitive level groups : normal ( IQ>90 ) , borderline ( 70<IQ<89 ) and impaired ( 50<IQ<69 ) were examined . The impaired group had more severe autism symptoms than the borderline and the normal cognitive groups . However , following intervention the groups did not differ in the change in core autism symptoms . IQ scores increased significantly more in the autism group than in the DD group . IQ improvements correlated significantly with reduction in autism symptoms and mostly in stereotyped behaviors . CONCLUSIONS Cognitive ability in autism is associated with autism severity . Two distinct subtypes based on cognitive level are identified . However , baseline cognitive level can not predict the progress rate in autism symptoms with intervention . Improvement of social-communicative behaviors and the intensive intervention are related to significant cognitive increments in autism
