A recent study posted in Environmental International measured flouride in 213 pregnant women living in Mexico City. They found a higher concentration of maternal urinary fluoride was associated with more ADHD-like symptoms in school-age children.
“Our findings show that children with elevated prenatal exposure to
fluoride were more likely to show symptoms of ADHD as reported by
parents. Prenatal fluoride exposure was more strongly associated with
inattentive behaviours and cognitive problems, but not with
hyperactivity,” said Bashash (lead researcher) .
This work builds off of previous research the team published on this
population demonstrating that higher levels of urine fluoride during
pregnancy are associated with lower scores on tests of IQ and cognition
in the school-age children.
These findings are consistent with the growing body of evidence suggesting neurotoxicity of early-life exposure to fluoride.
