Brain Differences in Autism and Aspergers

Researchers have found distinct differences between children with autism and Aspergers in regards to brain connectivity: 

At first, the test showed that children with Asperger's and those with autism were similar: both showed weaker connections, compared with typically-developing children, in a region of the brain's left hemisphere called the arcuate fasciculus, which is involved in language.

However, when looking at connectivity between other parts of the brain, the researchers saw differences. Connections between several regions in the left hemisphere were stronger in children with Asperger's than in both children with autism and typically-developing children.

The results suggest the conditions are related, but there are physiological differences in brain connectivity that distinguish children with Asperger's from those with autism, according to the study published Wednesday (July 31) in the journal BMC Medicine.

With the disorders being lumped together in the DSM, it can make it harder to standardize care.  They go on to say that it's important to determine how the two disorders are different so that treatment will be most effective. 

What do you think about the research?
