The number of the nation's children diagnosed with Autism Spectrum Disorder is on the rise.
The Centers for Disease Control estimates 1 in 110 children has the communication and social skills disorder, which is up 57 percent since experts last collected data 4 years ago.
Researchers from the CDC and other sites looked at data on 8-year-olds because most cases are diagnosed by then. There is a striking difference in rates between boys and girls. Experts estimate 1 in 315 girls has some form of autism. For boys, that number jumps to 1 in 70.
CDC researchers have not been able to pinpoint a reason for the increase.
They said it could be because of better detection or that cases could truly be rising.
