Interventions for anxiety may help people with autism spectrum disorder
A new study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging reports that anxiety occurring in autism spectrum disorder (ASD) shares similar brain mechanisms as anxiety alone. Led by Drs. John Herrington and Robert Schultz of the Center for Autism Research, a joint research center of the Children's Hospital of Philadelphia and University of Pennsylvania, the study could be good news for treating anxiety symptoms in ASD. The findings suggest that treatments that work for anxiety disorders may also help people with anxiety and ASD.

Gut microbes may talk to the brain through cortisol
Gut microbes have been in the news a lot lately. Recent studies show they can influence human health, behavior, and certain neurological disorders, such as autism. But just how do they communicate with the brain? Results from a new University of Illinois study suggest a pathway of communication between certain gut bacteria and brain metabolites, by way of a compound in the blood known as cortisol. And unexpectedly, the finding provides a potential mechanism to explain the characteristics of autism.
