"Based on the above mentioned research, approximately 53% percent of the increase in autism prevalence over time may be explained by changes in diagnosis (26%), greater awareness (16%), and an increase in parental age (11%). While this research is beginning to help us understand the increase in autism prevalence, half of the increase is still unexplained and not due to better diagnosis, greater awareness, and social factors alone. Environmental factors, and their interactions with genetic susceptibilities, are likely contributors to increase in prevalence and are the subject of numerous research projects currently supported by Autism Speaks.
The increase in autism prevalence is real and the public health crisis is growing. More families are affected by autism today then ever before."
The above statement by Autism Speaks was based on several published sources and CDC information. including articles by authors Bearman and King, who have indicated that approximately 50% (47%) of autism prevalence increases are based on factors other than social factors. Now Autism Speaks and the Centers for Disease Control and Prevention (CDC) are co-sponsoring a workshop on February 1, 2011 to investigate the changes in autism prevalence over time in the United State:
"The purpose of this workshop is to identify promising directions, priorities, and needs for better understanding ASD prevalence trends. The workshop will include presentations on what has been done to understand reasons for ASD prevalence changes, examples of understanding prevalence change from other conditions, and panel breakout sessions to allow for further discussions.
This meeting is open to the public with pre-registration required by January 24, 2011 for US citizens and January 13 for non-US citizens."

While Autism Speaks has been puzzling at times in its efforts to "speak" about autism disorders, promoting the careers of purported autism spokespersons who question the very existence of autism as a medical disorder, the importance of the above initiative can not be overstated. For far too long the "it's gotta be genetic" mindset has held sway and prevented substantial scientific exploration of possible environmental causes or triggers of autism. Hopefully the recent US Senate hearings, official statements by the IACC acknowledging the emergence of a gene environment interaction paradigm, the CHARGE study, work by Dr. Irva Hertz-Picciotto and UN Davis M.I.N.D. researchers, and efforts like the Autism Speaks/CDC prevalence workshop will lead to further environmental autism research; research which should have been commenced years ago.
