It found that a brain scan and computer algorithm using five different measurements of brain shape and structure was up to 85% accurate in identifying the autistic spectrum disorder (ASD) in adults. These measurements could be used as a “biomarker” for autistic spectrum disorders, the researchers say.

What does a big head on a baby mean?

Macrocephaly is the term for an unusually large head. An infant with macrocephaly will have a larger head than most other infants of the same age and sex. In many cases, this condition is benign or harmless. In other cases, it may indicate an underlying medical condition, such as a genetic syndrome or a brain tumor.

What does autism look like on the brain?

Specifically, in autistic brains there is significantly more folding in the left parietal and temporal lobes as well as in the right frontal and temporal regions. “These alterations are often correlated with modifications in neuronal network connectivity,” Dr. Culotta says.

Are autistic brains physically different?

The brains of people with autism show a variety of structural differences from those of controls, according to a large imaging study¹. The differences appear throughout the brain, not just in regions linked to the condition. The findings suggest that many more regions are involved in autism than previously thought.

What causes autism in the brain?

Studies suggest that ASD could be a result of disruptions in normal brain growth very early in development. These disruptions may be the result of defects in genes that control brain development and regulate how brain cells communicate with each other. Autism is more common in children born prematurely.
