Brain development in children

“The list of chemicals that can affect brain development in children has grown. In a study out today in The Lancet Neurology, researchers outline new chemicals that may be contributing to what they dub the “global, silent pandemic of neurodevelopmental toxicity.” In 2006, the team had released a list of five neurotoxins that may contribute to everything from cognitive deficits to attention problems. Now that list is expanded, based on new research that has since accumulated on chemicals linked to developmental disorders in children. Today, they outline six more.” Forbes

Summary in The Lancet Neurology.  “Neurodevelopmental disabilities, including autism, attention-deficit hyperactivity disorder, dyslexia, and other cognitive impairments, affect millions of children worldwide, and some diagnoses seem to be increasing in frequency. Industrial chemicals that injure the developing brain are among the known causes for this rise in prevalence. In 2006, we did a systematic review and identified five industrial chemicals as developmental neurotoxicants:

  • lead,
  • methylmercury,
  • polychlorinated biphenyls,
  • arsenic,
  • and toluene.

Since 2006, epidemiological studies have documented six additional developmental neurotoxicants—

  • manganese,
  • fluoride,
  • chlorpyrifos,
  • dichlorodiphenyltrichloroethane,
  • tetrachloroethylene,
  • and the polybrominated diphenyl ethers.

We postulate that even more neurotoxicants remain undiscovered. To control the pandemic of developmental neurotoxicity, we propose a global prevention strategy. Untested chemicals should not be presumed to be safe to brain development, and chemicals in existing use and all new chemicals must therefore be tested for developmental neurotoxicity. To coordinate these efforts and to accelerate translation of science into prevention, we propose the urgent formation of a new international clearinghouse.”

Nice post, I really like the way you share the information about brain development in children.
