Question

A general finding is that the brains of young autistic children exhibit?

1) reduced volume of the hippocampus.
2) enlarged brain size of around 10 percent.
3) fewer axons within the corpus callosum.
4) loss of cells within the cerebral cortex.
5) increased volume of the brain ventricles.

Answer 1

The general finding for the brains of young autistic children is an increased volume of the brain ventricles.

Step-by-step explanation:

The general finding for the brains of young autistic children is an increased volume of the brain ventricles. This can be seen in Figure 35.30 which shows a comparison between a normal brain and the brain of a patient with Alzheimer's Disease. The brain from the patient with Alzheimer's Disease exhibits neurodegeneration, particularly within the ventricles and hippocampus. This finding suggests that there may be structural differences in the brains of autistic children that contribute to the symptoms of autism.
