Catherine DeSoto, PhD Department of Psychology, University of Northern Iowa, Cedar Falls, Iowa, cathy.desoto(a)uni.edu Robert T. Hitlan, PhD Department of Psychology, University of Northern Iowa, Cedar Falls, Iowa 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.

Some serious stuff here! So I wonder why all our Pharma 'activists' in these ngs are so silent about this info??? "...a significant relation does exist between the blood levels of mercury and diagnosis of an autism spectrum disorder." Still waiting for comments... Yuri. Yuri Kuchinsky -- http://www.globalserve.net/~yuku "I have not seen autism with the Amish," said Dr. Frank Noonan, a family practitioner in Lancaster County, Pa., who has treated thousands of Amish for a quarter-century. "You'll find all the other stuff, but we don't find the autism. We're right in the heart of Amish country and seeing none, and that's just the way it is."

For a detailed discussion of this paper, see http://www.autismstreet.org/weblog/?p=158 (The writers of the discussion were not particularly impressed by the statistical methodology used by DeSoto and Hitlan. Just so you'll be prepared.) -- David Wright :: alphabeta at prodigy.net These are my opinions only, but they're almost always correct.

A search at PubMed for "autism misdiagnosis" turns up 5 results. Not one of them is mercury poisoning. A search at PubMed for "mercury poisoning misdiagnosis" turns up zero results. End Quote. Drop the word misdiagnosis and see how many are there. > > (The writers of the discussion were not particularly impressed by the > statistical methodology used by DeSoto and Hitlan.
