Research and Autism News News By State California Autism News

August 9, 2016- "Study: Younger Siblings Face Higher Autism Risk"- A new study suggests younger siblings of those with autism are over a dozen times more likely than other kids to have the developmental disorder as well. The study determined that risk did not appear to change based on a child’s race or whether they were born early, at term, or late. However, the risk was higher for boys with older brothers with autism at 15 percent, compared to girls with affected older sister who were diagnosed 7 percent of the time.
