Early Signs of Autism

This Chicago Tribune article entitled "Study Finds Early Signs of Autism in Baby Brains" reports on recent research finding that the brains of infants who later were diagnosed with autism actually responded differently to eye contact with another person than did the brains of infants who were never diagnosed with autism. Although the researchers call for additional study, this research is intriguing in that it may allow for very early identification and potential treatment of autism. What other research is needed in this situation? How might early identification change the treatment of autism?
