Some children with autism spectrum disorders (ASDs) exhibit low mental age (Low-MA; i.e., cognitive functioning below 12 months). We examined diagnosis, symptom severity, and development in children with ASD-low MA (n = 25), autistic disorder (n = 111), and PDD-NOS (n = 82) at ages two and four. We predicted that some ASD-low MA children would…

We compared the cognitive and language development at 4, 14, 24, 36, 54 months, and 7 years of siblings of children with autism (SIBS-A) to that of siblings of children with typical development (SIBS-TD) using growth curve analyses. At 7 years, 40% of the SIBS-A, compared to 16% of SIBS-TD, were identified with cognitive, language and/or academic…
