U.K. researchers assessed the brain functioning of babies age 6 months to 10 months who had an older sibling with autism and found that they had different brain responses to eye contact than those who did not have an increased risk of the condition. In the journal Current Biology, they cautioned that not all of the babies showing these differences in brain function were later diagnosed with autism, suggesting that more work is needed to make the testing clinically relevant.
