– Researchers used advanced MRI techniques to examine the brain structures of 142 autistic children and compare them to 8,971 non-autistic children.
– The scans revealed differences in neuron densities in parts of the cerebral cortex involved in learning, reasoning, problem-solving and memory formation. Specifically, lower densities were found.
– Higher neuron densities were detected in the amygdala, a region important for processing emotions.
– These differences were specific to autism and not seen when comparing autistic kids to those with ADHD or anxiety.
– The imaging methods allowed tracking changes as the children developed over a couple years.
– The findings provide insights into characteristics of autism and open opportunities to identify individuals who could benefit from targeted therapies.
– Longitudinal studies are continuing to better understand brain changes in autism from childhood to early adulthood using these advanced scanning techniques.
