Reduced levels of mercury in first baby haircuts of autistic children.

Holmes AS, Blaxill MF, Haley BE.

Reported rates of autism have increased sharply in the United States

and the United Kingdom. One possible factor underlying these increases

is increased exposure to mercury through thimerosal-containing vaccines,

but vaccine exposures need to be evaluated in the context of cumulative

exposures during gestation and early infancy. Differential rates of

postnatal mercury elimination may explain why similar gestational and

infant exposures produce variable neurological effects. First baby

haircut samples were obtained from 94 children diagnosed with autism

using Diagnostic and Statistical Manual of Mental Disorders, 4th edition

(DSM IV) criteria and 45 age- and gender-matched controls. Information

on diet, dental amalgam fillings, vaccine history, Rho D immunoglobulin

administration, and autism symptom severity was collected through a

maternal survey questionnaire and clinical observation. Hair mercury

levels in the autistic group were 0.47 ppm versus 3.63 ppm in controls,

a significant difference. The mothers in the autistic group had

significantly higher levels of mercury exposure through Rho D

immunoglobulin injections and amalgam fillings than control mothers.

Within the autistic group, hair mercury levels varied significantly

across mildly, moderately, and severely autistic children, with mean

group levels of 0.79, 0.46, and 0.21 ppm, respectively. Hair mercury

levels among controls were significantly correlated with the number of

the mothers' amalgam fillings and their fish consumption as well as

exposure to mercury through childhood vaccines, correlations that were

absent in the autistic group. Hair excretion patterns among autistic

infants were significantly reduced relative to control. These data cast

doubt on the efficacy of traditional hair analysis as a measure of total

mercury exposure in a subset of the population. In light of the

biological plausibility of mercury's role in neurodevelopmental

disorders, the present study provides further insight into one possible

mechanism by which early mercury exposures could increase the risk of

autism.

I havn't really heard anything about the possibility of the mercury

from a mother's fillings being passed along to her baby as a possible

cause of autism. I have a mouth full of silver filings, many of

which were put in when I was very young (5 - 10 years old probably).

I gave birth to my son when I was 35 yrs. (I'm 42 now) and some of my

fillings are now having to be replaced they are so old and falling

apart. My son (who is pretty high functioning) was born 3 mos.

premature and weighed 2 lbs. 11 oz. when born. I've always suspected

he was autistic " from birth " because I don't remember any significant

milestones and then regression. And I've often wondered if the

mercury from my fillings was the trigger that started everything.
