Environment, Genetics and Autism
- A Positive Association found between Autism Prevalence and Childhood Vaccination uptake across the U.S. Population A 1% increase in vaccination was associated with an additional 680 children having AUT [autism] or SLI [speech or language impairment].
- Genetic Heritability and Shared Environmental Factors Among Twin Pairs With Autism To our knowledge, this study [published Nov 2011] is the largest population-based twin study of autism that used contemporary standards for the diagnosis of autism… .The results suggest that environmental factors common to twins explain about 55% of the liability to autism. Although genetic factors also play an important role, they are of substantially lower magnitude than estimates from prior twin studies of autism.

Gastrointestinal Disease and Autism
- ‘Controversial Doctor and Autism Media Channel Director proven right – MMR Vaccine Causes Autism & Inflammatory Bowel Disease.’ Two landmark events – a government concession in the US Vaccine Court, and a groundbreaking scientific paper – confirm that physician, scientist, and Autism Media Channel [AMC] Director, Dr. Andrew Wakefield, and the parents were right all along.
- Impaired Carbohydrate Digestion and Transport and Mucosal Dysbiosis in the Intestines of Children with Autism and Gastrointestinal Disturbances
- Children with autism spectrum disorders (ASD) who exhibit chronic gastrointestinal (GI) symptoms and marked fluctuation of behavioral symptoms exhibit distinct innate immune abnormalities and transcriptional profiles of peripheral blood (PB) monocytes

Metals, Environmental Toxins, and Autism
- Autism & Aluminum Adjuvants In Vaccines – How Aluminum Adjuvants in Vaccines Can Cause Autism – Informed Consent Action Network (PDF)
- A comparative evaluation of the effects of MMR immunization and mercury doses from thimerosal-containing childhood vaccines on the population prevalence of autism The results of this study agree with a number of previously published studies. These studies have shown that there is biological plausibility and epidemiological evidence showing a direct relationship between increasing doses of mercury from thimerosal-containing vaccines and neurodevelopmental disorders, and measles-containing vaccines and serious neurological disorders.
- A two-phase study evaluating the relationship between Thimerosal-containing childhood vaccine administration and the risk for an autism spectrum disorder diagnosis in the United States Download the PDF to read the conclusion that the present study provides new epidemiological evidence supporting an association between increasing organic-Hg exposure from Thimerosal-containing childhood vaccines and the subsequent risk of an ASD diagnosis.
- Empirical Data Confirm Autism Symptoms Related to Aluminum and Acetominophen Exposure
- Toxicological Status of Children with Autism vs. Neurotypical Children and the Association with Autism Severity Overall, children with autism have higher average levels of several toxic metals, and levels of several toxic metals are strongly associated with variations in the severity of autism for all three of the autism severity scales investigated.
- Autism Spectrum Disorders and Aluminum Vaccine Adjuvants research data suggests that vaccines containing Al may be a contributing etiological factor in the increasing incidence of autism.
- Sorting out the spinning of autism: heavy metals and the question of incidence The question about toxic exposure and autism is open, with the weight of evidence favoring a connection that is not well understood.
- Do aluminum vaccine adjuvants contribute to the rising prevalence of autism? The application of the Hill’s criteria to these data indicates that the correlation between Al in vaccines and ASD may be causal.
- Aluminium in brain tissue in autism The pre-eminence of intracellular aluminium associated with non-neuronal cells was a standout observation in autism brain tissue and may offer clues as to both the origin of the brain aluminium as well as a putative role in autism spectrum disorder.
- A case series of children with apparent mercury toxic encephalopathies manifesting with clinical symptoms of regressive autistic disorders
- Mercury in first-cut baby hair of children with autism versus typically-developing children The amount of Hg in the baby hair of children with autism showed a significant correlation with the number of maternal dental amalgams. The lower level of Hg in the baby hair of children with autism indicates an altered metabolism of Hg, and may be due toa decreased ability to excrete Hg. This is consistent with usage of higher amounts of oral antibiotics… Higher usage of oral antibiotics in infancy may also partially explain the high incidence of chronic gastrointestinal problems seen in individuals with autism.

Acetaminophen and Autism
- Acetaminophen (paracetamol) use, measles-mumps-rubella vaccination, and autistic disorder: the results of a parent survey This preliminary study found that acetaminophen use after measles-mumps-rubella vaccination was associated with autistic disorder.
- Did Acetaminophen Provoke the Autism Epidemic? Considerable evidence supports this contention, most notably the exponential rise in the incidence of autism since 1980, when acetaminophen began to replace aspirin for infants and young children.

Neuroimmune Disorders and Autism
- Extracellular Mitochondrial Components Secreted from Activated Live Mast Cells Act as “Innate Pathogens” and Contribute to Autism Pathogenesis Recent results from the Centers of Disease Control in the USA indicate that as many as 1/80 children have ASD. Many such children regress at about 3 years, often after a specific event such as reaction to vaccination
- Autism: an emerging ‘neuroimmune disorder’ in search of therapy
- A possible central mechanism in autism spectrum disorders, part 1 A careful review of ASD cases discloses a number of events that adhere to an immunoexcitotoxic mechanism. This mechanism explains the link between excessive vaccination, use of aluminum and ethylmercury as vaccine adjuvants, food allergies, gut dysbiosis, and abnormal formation of the developing brain.

These studies have shown that there is biological plausibility and epidemiological evidence showing a direct relationship between increasing doses of mercury from thimerosal-containing vaccines and neurodevelopmental disorders, and measles-containing vaccines and serious neurological disorders.
- Extracellular Mitochondrial Components Secreted from Activated Live Mast Cells Act as “Innate Pathogens” and Contribute to Autism Pathogenesis Recent results [as of April 2013] from the Centers of Disease Control in the USA indicate that as many as 1/80 children have ASD. Many such children regress at about age 3 years, often after a specific event such as reaction to vaccination

- Elevated levels of measles antibodies in children with autism …autistic children have a hyperimmune response to measles virus, which in the absence of a wild type of measles infection might be a sign of an abnormal immune reaction to the vaccine strain or virus reactivation.

- Autism Studies & Related Medical Conditions by Talk About Curing Autism (TACA); published in 2008.
- Vaccines & Autism: What do Epidemiological Studies Really Tell Us? There are 16 epidemiological studies here on MMR vaccines, thimerosal and autism. These studies represent the most often cited papers by scientists, public health officials and members of the media when trying to refute any evidence of an association between vaccinations and autism.
There are serious methodological limitations, design flaws, conflicts of interest or other problems related to each of these 16 studies. These flaws have been pointed out by government officials, other researchers, medical review panels and even the authors of the studies themselves. - 100 Research papers supporting Vaccine/Autism Causation
