Rates of autism spectrum disorder (ASD) are not creeping up so much as leaping up. New numbers just released by the Centers for Disease Control and Prevention reveal that one in 68 children now has a diagnosis of ASD—a 30 percent increase in just two years. In 2002, about one in 150 children was considered autistic and in 1991 the figure was one in 500.The staggering increase in cases of ASD should raise more suspicion in the medical community about its misdiagnosis and overdiagnosis than it does.
