Earlier this week we posted the results of scientific research indicating that flame retardants are among the current top killers of IQ in the U.S. Now the results of another new study appear to support these findings. The results of the current scientific study indicate that the children of mothers exposed to flame retardants during their pregnancy have an increased risk for the type of cognitive deficits that lead to reading problems.
In the current study, the researchers hypothesized that in utero exposure to polybrominated diphenyl ethers (PBDEs) — a type of flame retardant that is known to have adverse effects on brain development — might alter the brain processes involved in reading.
The research team analyzed neuro-imaging data from thirty-three 5-year-old children — all novice readers — who were first given a reading assessment to identify reading problems. They also used maternal blood samples, taken during pregnancy, to estimate prenatal exposure to PBDEs.
Study results overview
The results indicate that children with greater exposure to PBDEs had a less efficient brain network for reading.
“Our findings suggest that exposure to PBDEs doesn’t affect the whole brain — just the regions associated with reading.”
