Autism predicted by infant brain changes, study says.

Yet, for infants who have an autistic sibling, the risk of developing the disorder may be as high as one in five.

Hazlett and her colleagues studied two groups of infants: a high-risk group of 106 infants who had an older sibling with autism and a low-risk group of 42 infants with no immediate family history of autism.

The research team used MRI technology to measure brain development for each infant at set time points between 6 months and 24 months of age.

Hazlett and her colleagues discovered an overgrowth of cortical surface area in infants later diagnosed with autism, compared with the typically developing infants.

Using the algorithm, the researchers also made near-perfect predictions about which babies would not develop autism by age 2.

At 24 months, the kids who developed autism had significantly bigger brains, according to Piven,
