The question of what is leading to the apparent increase in autism is of great importance. Like the link between aspirin and heart attack, even a small effect can have major health implications. If there is any link between autism and mercury, it is absolutely crucial that the first reports of the question are not falsely stating that no link occurs. We have reanalyzed the data set originally reported by Ip et al. in 2004 and have found that the original p value was in error and that a significant relation does exist between the blood levels of mercury and diagnosis of an autism spectrum disorder. Moreover, the hair sample analysis results offer some support for the idea that persons with autism may be less efficient and more variable at eliminating mercury from the blood.

Desoto MC, Hitlan RT J Child Neurol 2007 Nov 22(11):1308-11  I found this article oddly exciting and disturbing because it involved the re-analysis of a classic paper {1} used to debunk the mercury hypothesis of autism spectrum disorder and the original conclusion is now in doubt. This re-analysis does not prove the mercury hypothesis by any stretch of the imagination but it does suggest that we have been too definitive in ruling it out. The result shown here does point out the need to be meticulous in statistical analysis both in the arithmetic and also in stating the hypothesis (e.g. as a one-tailed experiment). It certainly will re-ignite a controversy where, alas, there is more heat than light. For those of us involved in the study of the genomic underpinnings of autism spectrum disorder, this should encourage us to even greater rigor. {1} Ip et al.
