ST. LOUIS, Mo. (KMOX) — A new local study find the risk of autism in siblings is nearly double prior estimates.
Washington University School of Medicine was one of 12 U.S. and Canadian sites to conduct this study. Psychiatrist Dr. John Constantino led the local study and says the rate in previous studies suggested the risk to be somewhere between 8-15 percent. Now the study puts the rate closer to 20 percent.
Constantino says the good news is that some of the children who were diagnosed very early may either outgrow it or may improve over time to the extent they would no longer qualify for a diagnosis when they get older.
The number of children diagnosed with autism has increased by 600 percent in the past two decades.
