A neuroimaging study found that autistic individuals whose cortical thickness deviated most from that of neurotypical peers tended to experience greater social and communication difficulties. In ...

For decades, researchers have been trying to understand the biological roots of autism spectrum disorder (ASD), a common neurodevelopmental condition that shapes how people communicate, learn and ...

The results provide a more detailed view of biological mechanisms associated with autism. Autistic participants had more dopamine D2 receptors than neurotypical participants, suggesting that the ...

Researchers have uncovered a surprising molecular chain reaction in the brain that may play a role in some forms of autism. The study suggests that nitric oxide, a tiny signaling molecule normally ...

Researchers used brain scans in 60 adults to examine dopamine receptors, glucose metabolism, and brain connectivity. Autistic ...

"Autism spectrum disorder (autism) and attention-deficit/ hyperactivity disorder (ADHD) often co-occur, although it remains unclear whether these conditions share common neurobiological foundations or ...

A study in Biological Psychiatry provides a new understanding of brain alterations in children with autism spectrum disorder (ASD) that may help researchers and clinicians better define the disorder.

Scientists are uncovering a surprising connection between autism and ADHD that goes deeper than labels. Instead of diagnoses, it’s the severity of autism-like traits that seems to shape how the brain ...

The gut brain axis is an important relationship very few people discuss or even understand. It is composed of a two-way communication system between your gut (digestive system) and your brain which ...
