Scientists Link Autism To These Toxic Chemicals During Fetal Development Autism and intellectual disability (ID) rates are linked with exposure to harmful environmental factors during congenital development.
Essentially what happens is during pregnancy… there are certain sensitive periods where the fetus is very vulnerable to a range of small molecules – from things like plasticisers, prescription drugs, environmental pesticides and other things. Some of these small molecules essentially alter normal development. Autism appears to be strongly correlated with rate of congenital malformations of the genitals in males across the country, this gives an indicator of environmental load and the effect is surprisingly strong. The strongest predictors for autism were associated with the environment; congenital malformations on the reproductive system in males.
Our environment is full of neurodevelopmental toxins, which means they alter how the brain grows. Mercury, polychlorinated diphenyl, lead, brominated flame retardants and pesticides are a few of many examples. Don’t forget about insecticides and herbicides.
Another recent study published in the New England Journal of Medicinecompared brain autopsies of autistic children who had died from unrelated causes to those of normal ones. The autistic brains demonstrated abnormal patches of disorganized neurons that disrupted the usual distinct layers in the brain’s cortex. The study suggests that abnormalities occurred in utero during key developmental stages between 19 to 30 weeks gestation.
It’s not just the toxin, it’s the timing of the exposure as well.
