move down mercury theory
Diagnoses of autism has increased from 1:10,000 in 1988 to as high as 1 in 150 people <ref>http://www.cdc.gov/ncbddd/autism/faq_prevalence.htm</ref>, and it has been rising. Among boys, 1 in 94 has the disorder. In New Jersey, which has the highest rate in the nation, 1 in every 60 boys has autism and 1 in every 94 children is affected.

Autism is a spectrum disorder which means there is a range in how it affects different people. There is the fragile x syndrome, Asperger's syndrome, pdd nos, mild autism, moderate autism, severe autism, and some [[idiot savants]]. Autistic children will not all act like the character portrayed in the movie ''[[Rain Man]]''. Nor are all autistic children uncaring or unable to show emotion, in fact many are very caring.

As noted above, there is a strong interest in whether a possible link exists between the increasing numbers of people being diagnosed with autism, and the use of thimerosal (which contains mercury) as a preservative in vaccines. However, this has been disproved as a likely cause of autism and now most data indicates that autism is a mostly genetic condition. <ref> ''American Acadamy of Family Physicians'' http://www.aafp.org/afp/20020301/tips/14.html </ref>. The genetics of this condition are not yet fully understood and could be caused by complex interactions between multiple genes which would account for the "spectrum" like differences in the severity of many cases <ref> http://66.102.1.104/scholar?hl=en&lr=&q=cache:7kMNqvTgRtoJ:www.ikhebeenvraag.be/mediastorage/FSDocument/52/Freitag-2.pdf+</ref><ref>http://www.ncbi.nlm.nih.gov/pubmed/17764594</ref>
