The September issue of the Journal of the American Academy of Pediatrics will contain the results of a study of risk for autism in infants who have at least one older sibling diagnosed on the autism spectrum.

Dr. Sally Ozonoff of the MIND Institute has reported the resullts of an infant study conducted in 12 sites in the U.S. and Canada involving over 600 infants born to families with at least one diagnosed biological child with an autism spectrum disorder.  Until this study, it was thought that the risk of having another child born with some form of au%ism was between 3% and 10%.  The new study shows the rate in a family with one older diagnosed sibling at 19% and the rate of families with two or more older siblings with some form of autism to be 32%.  For more information on the study, go to www.aap.org
