Number of U.S. Children With Autism Up 50% in Two Years

The incidence of autism spectrum disorder in eight-year-olds in the U.S. has risen by 50% since 2007, from one in 150 to one in 100, according to a CDC report that will be released later this year. However, the higher rate might not mean that more U.S. children have autism spectrum disorder, but instead that physicians’ ability to detect the disorder is improving, according to Tom Insel, director of the National Institute of Mental Health.
