SUMMARY

Cyclical processes involved in the metabolism of essential and toxic elements during fetal and early postnatal development differ significantly in children with attention deficit-hyperactivity disorder (ADHD) and/or autism spectrum disorder (ASD) and neurotypical children, according to a small study of tooth matrix biomarkers. The study’s findings suggest that metabolic regulation of nutrients and toxins may play a role in the development of ADHD and autism.

Summary

Among U.S. children and adolescents, the estimated prevalence of diagnosed ADHD increased significantly between 1997-1998 and 2015-2016, from 6.1% to 10.2%. The continuous increase in the prevalence of diagnosed ADHD was consistent across all subgroups.

Neurodevelopmental disorders are much more common in children who received mercury-containing vaccines.

A dose-response relationship between organic mercury exposure from thimerosal-containing vaccines and neurodevelopmental disorders

SUMMARY

On a per microgram of organic-mercury (Hg) basis, pervasive developmental disorder, specific developmental disorder, tic disorder and hyperkinetic syndrome of childhood cases were significantly more likely than controls to receive increased organic-Hg exposure. This study provides new epidemiological evidence supporting a significant relationship between increasing organic-Hg exposure from vaccines and the subsequent risk of a neurodevelopmental disorder diagnosis.

SUMMARY

“Consistent significantly increased rate ratios were observed for autism, autism spectrum disorders, tics, attention deficit disorder, and emotional disturbances with Hg [mercury] exposure from TCVs [thimerosal-containing vaccines]. By contrast, none of the control outcomes had significantly increased rate ratios with Hg exposure from TCVs.”

TITLE

Activation of methionine synthase by insulin-like growth factor-1 and dopamine: a target for neurodevelopmental toxins and thimerosal

SUMMARY

“The ethylmercury-containing preservative thimerosal inhibited both IGF-1- and dopamine-stimulated methylation with an IC50 of 1nM and eliminated MS activity. Our findings outline a novel growth factor signaling pathway that regulates MS activity and thereby modulates methylation reactions, including DNA methylation. The potent inhibition of this pathway by ethanol, lead, mercury, aluminum and thimerosal suggest that it may be an important target of neurodevelopmental toxins.”
