Mercury Contamination of the Great Lakes
When I was growing up in Chicago in the 1950's, people fished in the Great Lakes, and they would eat the fish. Soon, it was no longer safe to eat fish from the Great Lakes, having been contaminated with Mercury. Government warnings tell us that eating the fish results in mercury toxicity.(9)

Pink Disease - Another Form of Mercury Toxicity
In the 1900's, an iatrogenic form of Mercury toxicity called "Pink Disease" was caused by teething powders containing mercury. Most kids seemed to do fine with it. However, about one in 500 children exhibited signs and symptoms of mercury toxicity. This suggests a genetic susceptibility in these few kids, perhaps an inability to detoxify mercury from the body.
Mercury Sensitivity - a Heritable Risk Factor for Autism
A 2010 study from Australia showed that infants with "Pink Disease" ancestry had an eight fold higher incidence of autism compared to the general population .(2) Pink disease was attributed to mercury containing teething powders in approx 1 in 500 exposed children. This study supports the hypothesis that Mercury sensitivity is a heritable risk factor for autism.(2)
Hepatitis B Injection Increases Autism Rate
A recent 2010 study shows that male neonates (newborns) vaccinated with the Mercury containing hepatitis B vaccine had a three-fold higher rate of autism compared to controls.(1) Perhaps these newborns had a reduced ability to handle the Mercury load.
Biological Plausibility
- Increasing Autism Cases
The
biological plausibility of Mercury exposure as a causative factor in
genetically susceptible children is explored in this 2011 article from Australia by Garrecht (8), and in this 2010 article by Geier.(3)
Left Image: Increasing autism cases.
The
science is quite clear that Mercury is a neuro-developmental toxin, so
it is surprising to me that mainstream medicine is still injecting
infants with mercury contained in the Hepatitis B vaccine. California
has banned the use of mercury containing vaccines in infants and
pregnant women since 2006.(8) The remaining states should follow California's lead.Link Denied for Economic Reasons
It is also quite clear that mainstream medicine must put its head in the sand and deny the plausible link between Mercury exposure and Autism. There is too much money at stake. If the link was to be accepted by mainstream medicine, the vaccine manufacturers and the government would be on the hook for billions in damages.
High Functioning Autism
For most, a diagnosis of Autism represents a form of disability, However, about 10% of persons with autism are "high functioning" with special mental abilities, called "savants". (5)

Autistic Boy Survives River
Another striking story from 1996 is the story of a ten year old autistic boy, Taylor, who survived 4 days floating on a river after becoming separated from his family. When asked how he could do it, his family provided some insight. He was incredibly focused, and had the ability to focus attention and fixate on one thing at a time:. A quote from the article:
"They
say they believe that it is possible that Taylor survived the horrors
of the swamp not in spite of his autism, but because of it.
''He doesn't know how to panic,'' Jayne said. ''He doesn't know what fear is.''Her brother is focused, she said. Mrs. Touchstone says Taylor will focus all his attention and energy on a simple thing -- he will fixate on a knot in a bathing suit's draw string -- and not be concerned about the broader realm of his life."(5)

by Temple Grandin.Doctors With High Functioning Autism ?
Frankly, many college and medical students are socially awkward, unemotional, and yet incredibly focused. A subset of college students have high functioning autism. How many of these shed their diagnosis of autism, finish college, enter medical school and eventually become doctors? We sometimes ponder this question sitting around the dinner table.

Universal hepatitis B vaccination was recommended for U.S. newborns in 1991; however, safety findings are mixed. The association between hepatitis B vaccination of male neonates and parental report of autism diagnosis was determined. This cross-sectional study used weighted probability samples obtained from National Health Interview Survey 1997-2002 data sets. Vaccination status was determined from the vaccination record. Logistic regression was used to estimate the odds for autism diagnosis associated with neonatal hepatitis B vaccination among boys age 3-17 years, born before 1999, adjusted for race, maternal education, and two-parent household. Boys vaccinated as neonates had threefold greater odds for autism diagnosis compared to boys never vaccinated or vaccinated after the first month of life. Non-Hispanic white boys were 64% less likely to have autism diagnosis relative to nonwhite boys.
Findings suggest that U.S. male neonates vaccinated with the hepatitis B vaccine prior to 1999 (from vaccination record) had a threefold higher risk for parental report of autism diagnosis compared to boys not vaccinated as neonates during that same time period. Nonwhite boys bore a greater risk.

Ancestry of pink disease (infantile acrodynia) identified as a risk factor for autism spectrum disorders. Shandley K, Austin DW. Swinburne Autism Bio-Research Initiative (SABRI), Brain and Psychological Sciences Research Centre, Swinburne University of Technology, Hawthorn, Victoria, Australia.
Pink disease (infantile acrodynia) was especially prevalent in the first half of the 20th century. Primarily attributed to exposure to mercury (Hg) commonly found in teething powders, the condition was developed by approximately 1 in 500 exposed children. The differential risk factor was identified as an idiosyncratic sensitivity to Hg. Autism spectrum disorders (ASD) have also been postulated to be produced by Hg. Analogous to the pink disease experience, Hg exposure is widespread yet only a fraction of exposed children develop an ASD, suggesting sensitivity to Hg may also be present in children with an ASD. The objective of this study was to test the hypothesis that individuals with a known hypersensitivity to Hg (pink disease survivors) may be more likely to have descendants with an ASD. Five hundred and twenty-two participants who had previously been diagnosed with pink disease completed a survey on the health outcomes of their descendants. The prevalence rates of ASD and a variety of other clinical conditions diagnosed in childhood (attention deficit hyperactivity disorder, epilepsy, Fragile X syndrome, and Down syndrome) were compared to well-established general population prevalence rates. The results showed the prevalence rate of ASD among the grandchildren of pink disease survivors (1 in 22) to be significantly higher than the comparable general population prevalence rate (1 in 160). The results support the hypothesis that Hg sensitivity may be a heritable/genetic risk factor for ASD.

Autism spectrum disorders (ASDs) also known as pervasive developmental disorders (PDD) are a behaviorally defined group of neurodevelopmental disorders that are usually diagnosed in early childhood. ASDs disproportionately affect male children. Mercury (Hg) a heavy metal, is widespread and persistent in the environment. Mercury is a ubiquitous source of danger in fish, drugs, fungicides/herbicides, dental fillings, thermometers, and many other products. Elevated Hg concentrations may remain in the brain from several years to decades following exposure. This is important because investigators have long recognized that Hg is a neurodevelopmental poison; it can cause problems in neuronal cell migration and division, and can ultimately cause cell degeneration and death. Case-reports of patients have described developmental regressions with ASD symptoms following fetal and/or early childhood Hg exposure, and epidemiological studies have linked exposure to Hg with an elevated risk of a patient being diagnosed with an ASD. Immune, sensory, neurological, motor, and behavioral dysfunctions similar to traits defining or associated with ASDs were reported following Hg intoxication with similarities extending to neuroanatomy, neurotransmitters, and biochemistry. The sexual dimorphism of ASDs may result from synergistic neurotoxicity caused by the interaction of testosterone and Hg; in contrast, estrogen is protective, mitigating the toxicity of Hg. Mercury exposure may significantly increase androgen levels, and as a result, patients diagnosed with an ASD may significantly benefit from anti-androgen therapy. Finally, the clinical geneticist has a wealth of biomarkers to evaluate and treat patients diagnosed with an ASD.

Autism No Handicap, Boy Defies Swamp By RICK BRAGG Published: August 17, 1996
They say they believe that it is possible that Taylor survived the horrors of the swamp not in spite of his autism, but because of it.
''He doesn't know how to panic,'' Jayne said. ''He doesn't know what fear is.''
Her brother is focused, she said. Mrs. Touchstone says Taylor will focus all his attention and energy on a simple thing -- he will fixate on a knot in a bathing suit's draw string -- and not be concerned about the broader realm of his life.
If that focus helped him survive, Mrs. Touchstone said, then ''it is a miracle'' that it was her son and not some otherwise normal child who went for a four-day swim in the black water of a region in which Army Rangers and sheriff's deputies could not fully penetrate. He may have paddled with the gators, and worried more about losing his trunks.

Savant syndrome, characterized by remarkable islands of mental ability in otherwise mentally handicapped persons, may occur in autistic as well as nonautistic individuals. Overall, approximately 10% of autistic persons exhibit savant abilities; roughly 50% of those with savant syndrome have autism, and the remaining 50% have other forms of developmental disability. Most commonly, savant syndrome takes the form of extraordinary musical abilities, but may also include calendar-calculation, artistic, mathematical, spatial, mechanical, and memory skills. While savant syndrome was first described more than a century ago, only recently have researchers begun to employ a more uniform nomenclature and more standardized testing in an effort to compare the abilities of savants with those of normal persons. Males show signs of savant syndrome approximately four times more often than females. Along with imaging study findings, this fact suggests the presence of a developmental disorder involving left-brain damage with right-brain compensation.

Counts of children diagnosed with autism for each year were taken from Table 1-9 of IDEA Part B Child Count (2005) and from Table 1-11 of IDEA Part B Child Count (2007). These were divided by census estimates for U.S. resident population aged 6–17 taken from US census estimates for 1990–1999 resident population by age and the similar estimates for 2000–2007; for all years, the September population estimates were used.
