Sub-acute chronic mercury exposure from dental mercury-silver fillings as well as environmental sources (coal burning plants) add to the body burden.  Vaccinations can contain thimerosal (mercury preservative) which in my estimation can cause an exagerated response to a residual body burden of mercuy.  Aluminum and lead make mercury 100 times more toxic through toxic synergism mentioned in a previous post.

Evidence of parallels between mercury intoxication and the brain pathology in autism

In 2000, Bernard and coauthors published a review of the similarities between Hg poisoning and the symptoms of autism. In their review, Bernard and colleagues pointed out 79 similarities between the symptoms of autism and the symptoms of mercury intoxication. Since that review, many more studies have become available to allow for the current comparison of the specific effects of Hg exposure in the brain and the similar pathological findings in those diagnosed with ASD (autism spectrum disorder) (see Table I for a summary of the parallels between symptoms of Hg intoxication in the brain and the brain pathology in ASD). The combined similarities outlined by these two reviews are too numerous to be a result of chance. Although there may be genetic or developmental components to autism, the evidence in this current review of the brain findings in autism clearly indicates the reality of brain injury in ASD; moreover, the brain injury symptoms which characterize autism closely correspond to those seen in sub-acute Hg intoxication. The evidence presented in this paper is consistent with mercury being identified as either causal or contributory, working synergistically with other compounds or pathogens in producing the brain pathology observed in those diagnosed with ASD.
