The claim behind chelation therapy for autism is that the condition is related to mercury poisoning. Remove the mercury, cure the autism. In a recent post on chelation related deaths I cited a lack of evidence for the claim.
Now in the interest of being fair and balanced I must acknowledge this paper which was just published in the Journal of American Physicians and Surgeons. Looking at trends in the diagnosis of autism and related disorders before and after thimerosal was removed from vaccines in the U.S. the study purports to show a decline in neurodevelopmental disorders which parallels the withdrawl of thimerosal. Thimerosal (AKA merthiolate) is a mercury containing preservative.
A press release accompanied the publication of this paper, which will probably receive heavy media coverage. A discussion at the Health Fraud List is critical of the study and cites this blog concerning the credibility of the authors.
Although I’m skeptical of this paper I lack expertise in the field and would welcome critical analysis from readers.
