Pittsburgh Early Autism Study

We are studying infants who have an older sibling diagnosed with an austism spectrum disorder (ASD) to look for infant behaviors that may predict a later ASD diagnosis. Family home videos of children later diagnosed with ASD suggest that diagnostic signs of ASD may emerge within the first year of life.
