Study: Autism Linked to Creases in Placenta

It could become a way to test babies before symptoms appear.

Children are not diagnosed with autism until after they are toddlers, but researchers may have now found a way to test children at birth. A new study has found that the placenta that once nourished children while they were in the womb has more creases and folds in families with a higher genetic risk for autism. The children in the study whose placentas were tested are all between ages 2 and 5, and they won’t know until next year if the placenta folds directly correlate to autism. But if it does, it could mean that children could be tested for autism as early as birth.
