UC-Boulder professor says the autism epidemic is real and therefore must be the product of an environmental factor.
A comparison of temporal trends in United States autism prevalence to trends in suspected environmental factors
Nevison CD. Environmental Health. 2014;13:73.
“Diagnosed autism prevalence has risen dramatically in the U.S over the last several decades and continued to trend upward as of birth year 2005. The increase is mainly real and has occurred mostly since the late 1980s. In contrast, children’s exposure to most of the top ten toxic compounds has remained flat or decreased over this same time frame. Environmental factors with increasing temporal trends can help suggest hypotheses for drivers of autism that merit further investigation.”
