NEW YORK, Dec. 24 (Xinhua) -- Autism diagnoses are undeniably on the rise in the United States, about 1 in 36 children have one, according to data the Centers for Disease Control and Prevention (CDC) collected from 11 states, compared with 1 in 150 children in 2000, and researchers have not yet arrived at a clear explanation.
"They attribute most of the surge to increased awareness of the disorder and changes in how it is classified by medical professionals," The New York Times reported on the development on Monday. "But scientists say there are other factors, genetic and environmental, that could be playing a role too."
