Today the latest report from the CDC’s Autism and Developmental Disabilities Monitoring (ADDM) Network was released. The ADDM is a surveillance network focused on following the prevalence of ASD. With the establishment of this network, we’ve been able to actually look at the prevalence rate of autism by estimating the rate from 8-year old children in 11 states across the U.S using the same approach each year. What is important about this approach is that prior to the establishment of this network, we were comparing prevalence estimates using different methodologies. We were essentially comparing apples to oranges, which made it difficult to draw conclusions about the rate of autism. With this network we’re able to compare apples to apples.
