Only a small fraction of autism therapies are supported by robust scientific evidence, according to three reviews published in the May issue of Pediatrics.

For many years, autism was considered synonymous with intellectual disability. A new study shows that perception is inaccurate.

In the new diagnostic manual for psychiatric disorders, Asperger syndrome will be folded into autism spectrum disorder. Francesca Happé, a member of the committee that made the recommendation, explains the rationale behind the decision.

Teenagers with autism can reliably measure their own quality of life and are more satisfied with it than are their parents, who over-emphasize their children’s social and emotional difficulties, according to a study published in February in The Journal of Developmental and Behavioral Pediatrics.

A genome-wide association study has identified risk factors for Asperger syndrome, some of which overlap with chromosomal regions implicated in autism, according to a study in the December issue of Autism Research.

Most studies define high-functioning children as those with an IQ above 70 or 80, but this is problematic for a number of reasons, say some scientists. The assumption underlying the use of high IQ as a synonym for high functioning is suspect because social and communicative abilities may have a far greater impact on an individual’s daily interactions.

A variant of the autism risk gene CNTNAP2 may alter the brain to emphasize connections between nearby regions and diminish those between more distant ones, according to a study published 3 November in Science Translational Medicine.

Children with autism show more activity in a brain region important for making decisions under changing circumstances, according to a poster presented Monday at the Society for Neuroscience annual meeting in San Diego.

In families with more than one child diagnosed with autism, younger siblings appear to be more severely affected by the disorder, according to new data presented Tuesday at the Society for Neuroscience annual meeting in San Diego.

Better performance on intelligence tests that measure spatial rather than verbal ability is inherited in people with autism, according to a paper published online in October in Human Genetics.
