Sciende Daily skrev:In the largest MRI study to date, researchers from Ben-Gurion University of the Negev and Carnegie Mellon University have shown that the brain anatomy in MRI scans of people with autism above age six is mostly indistinguishable from that of typically developing individuals and, therefore, of little clinical or scientific value.

The study, "Anatomical Abnormalities in Autism?" was just published in the Oxford journal Cerebral Cortex.

Dinstein believes that more complex explanations involving combinations of measures in more homogeneous sub-groups are likely to be the answer. "Expecting to find a single answer for the entire ASD population is naïve. We need to move on to thinking about how to split up this very heterogeneous group of disorders into more meaningful biologically-relevant subgroups," he says.
