Similar claims have been made by different reseachers. We searched the internet to find conflicting research but could find none. It is hard to imagine those advocating fluoridation would do so if there is any truth to these claims. Anyone knowing of research or data disproving these claims is requested to forward the information so it can be posted.

Fluride effect on IQ?
From Fluride Action Network http://www.fluoridealert.org/health/
"Fluoride's ability to damage the brain represents one of the most active areas of research on fluoride toxicity today.
The research has been fueled by recent human studies from China finding elevated levels of fluoride exposure to be associated with reduced cognitive ability in children.
The discovery of neurotoxic effects among fluoride-exposed humans is consistent with recent findings from over 30 animal studies published since 1992. As with the studies on humans, the studies on animals have reported an impairment in learning and memory processes among the fluoride-treated groups.
The animal studies have also documented considerable evidence of direct toxic effects of fluoride on brain tissue, even at levels as low as 1 ppm fluoride in water (Varner 1998). "
