Autistic facial characteristics identified.

This is a fascinating article; I’m trying to track down the original study online so I can read it. These boys were between the ages of 9 and 12 when their faces were scanned; I wonder if the phenotypical differences she identified exist earlier (i.e. in the first few years) to help with diagnosis. I also wonder if those facial differences persist into adulthood.

The summary says that the study identified two other subgroups with behavioral and language issues; but it does not say what those facial differences are. That is one reason why I want to read the original study, because Rob had major behavior issues, including repetitive behavior.
