Is an autistic person’s brain different from a non-autistic one?

Is an autistic brain 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 does an autistic person’s brain look like?

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.

What part of the brain is damaged in autism?

The cerebellum is one of the key brain regions affected by autism. The researchers found that neurons that lacked the RNF8 protein formed about 50 percent more synapses — the connections that allow neurons to send signals from one to another — than those with the gene. And the extra synapses worked.

How autistic brains are wired differently?

It suggests that the brains of autistic people are organised differently from those of other people; the area at the back of the brain, which processes visual information, is more highly developed. That leaves less brain capacity in areas which deal with decision-making and planning.

Can autism be seen in the brain?

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 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.
