  9. 10. Interesting Research One study focused on 48 children diagnosed with symptoms of autism. But by the time they had reached the age of 12-14 months, their average head size was in the top 15%. From then on, brain growth slowed. Comparisons with children free of signs of autism showed that on average, the children's head size was in the bottom 25% at birth.
