Children with autism spectrum disorders (ASD) tend to be fascinated by screen-based technology. A new study by a University of Missouri researcher found that adolescents with autism spend the majority of their free time using non-social media, including television and video-games.

Getting an autism diagnosis could be more difficult in 2013 when a revised diagnostic definition goes into effect. The proposed changes may affect the proportion of individuals who qualify for a diagnosis of autism spectrum disorder, according to preliminary data presented by Yale School of Medicine researchers at a meeting of the Icelandic Medical Association.

The underlying reason autism is often associated with gastrointestinal problems is an unknown, but new results to be published in the online journal mBio on January 10 reveal that the guts of autistic children differ from other children in at least one important way: many children with autism harbor a type of bacteria in their guts that non-autistic children do not. The study was conducted by Brent Williams and colleagues at the Mailman School of Public Health at Columbia University.

Potential clues to how autism miswires the brain are emerging from a study of a rare, purely genetic form of the disorders that affects fewer than 20 people worldwide. Using cutting-edge "disease-in a-dish" technology, researchers funded by the National Institutes of Health have grown patients' skin cells into neurons to discover what goes wrong in the brain in Timothy Syndrome. Affected children often show symptoms of autism spectrum disorders along with a constellation of physical problems.

Fragile X syndrome and tuberous sclerosis both cause autism and intellectual disabilities in a majority of affected patients. And both diseases have been linked to abnormalities in the amount of proteins made by brain cells at their synaptic junctions, suggesting that treatments for one disease may be applicable to the other. But new research reveals that the underlying cellular mechanisms of the two are polar opposites: while the genetic mutations that cause fragile x syndrome lead to an increase in synaptic protein synthesis, tuberous sclerosis is characterized by a dampening of the same pathway.

Autism researchers at the University of Pennsylvania School of Nursing have found a link between low birth weight and children diagnosed with autism, reporting premature infants are five times more likely to have autism than children born at normal weight.
