Landmark Study Finds:
Mercury Poisoning Causes Autism
A new study, “Biomarkers of Environmental Toxicity and Susceptibility in Autism” in the peer-reviewed Journal of the Neurological Sciences1, confirms a causal link between subacute mercury poisoning in children and their autism spectrum disorder (ASD) diagnosis. The autism community reported that this study presents, “…some compelling evidence…consistent with the author’s theory that mercury exposure plays a role in autism.”2 This paper3 presents the first prospective, blinded cohort study to examine children diagnosed with an ASD using: urinary porphyrin profile analysis (UPPA) to assess the body-burden and physiological effects of their mercury, glutathione analysis to assess susceptibility to mercury poisoning, and Childhood Autism Rating Scale (CARS) scores to measure ASD severity.

These evaluations4 established:
• Non-chelated patients diagnosed with an ASD had UPPA profiles indicative of mercury poisoning that strongly correlated with ASD severity, measured using CARS scores.
• Glutathione (a key biochemical in the body’s mercury detoxification pathway) was significantly lower in patients diagnosed with an ASD in comparison with its level in neurotypical controls.
• Increasing mercury-poisoning severity, as indicated by the UPPA results, was associated with lower glutathione levels among the patients diagnosed with an ASD.
Based upon these findings, the researchers concluded, “ASDs may result from a combination of genetic/ biochemical susceptibilities in the form of a reduced ability to excrete mercury and/or increased environ-mental exposures at key developmental times."
The Autism Research Institute, the non-profit CoMeD, Inc., and, through a grant from the Brenen Hornstein Autism Research & Education (BHARE) Foundation, the non-profit Institute of Chronic Illnesses, Inc. funded this research study.
Today, any parent, physician, or healthcare provider can easily confirm whether or not a non-chelated child diagnosed with an ASD is mercury poisoned by having UPPA testing run at LabCorp (CLIA-certified, test# 120980) or Laboratoire Philippe Auguste (ISO-certified, 119 Philippe Auguste Avenue, Paris, France 75011).
