Is there really an autism spectrum disorder epidemic?

Yes, by numbers: A recent report from the centers for disease control (cdc) estimated ASD at 1 in 88 live births, the highest estimate yet. This contrasts with estimates from 20 years ago of 5-10 in 10, 000. What is unclear is why this has changed so much. Some believe it mostly is because of changing definitions and increased recognition of the problem; others insist it is a true change. Time will tell.

More than Before: The definition of the disease has broadened over the years. Thus 1 reason for the increase.2.Better understanding of the disease has led to more more patients being diagnosed. And there may be more of it, but we are not sure why.

No: There is an epidemic of renaming some disorders and including them under the umbrella of autism spectrum disorder. Recently, Asperger's disorder, non verbal learning disability and many cases of mental retardation have been included.
