In late March, the US Centers for Disease Control and Prevention (CDC) released the newest estimates of prevalence of autism spectrum disorders in the United States, which suggest a 78% increase in the prevalence of these disorders since 2002 (http://www.cdc.gov/Features/CountingAutism/). The CDC now estimates there were 11.4 cases of these disorders per 1000 children at 8 years of age in 2008, compared with 6.4 per 1000 in 2002.
