  • Changed expressions of N-methyl-D-aspartate receptors in the brains of rats and primary neurons exposed to high level of fluoride

    Expressions of N-methyl-d-aspartic acid receptors (NMDARs) in the brains of rats and primary neurons exposed to high fluoride were investigated. Sprague-Dawley rats were divided randomly into a fluorosis group (50 ppm fluoride in the drinking water for 6 months) and controls (<0.5ppm fluoride) and the offspring from these rats sacrificed

  • Effect of fluoride exposure on the intelligence of school children in Madhya Pradesh, India.

    Objective: To assess the relationship between exposure to different drinking water fluoride levels and children's intelligence in Madhya Pradesh state, India. Materials and Methods: This cross-sectional study was conducted among 12-year-old school children of Madhya Pradesh state, India. The children were selected from low (< 1.5 parts per million) and high

  • Prenatal and postnatal ingestion of fluorides: fourteen years of investigation -- final report

    Three different sources of fluoride were used in this study. The tablets containing 1.0 mgm fluorine ion from CaF2; 1.2 mgm fluorine ion, from NaF and 0.825 mgm fluorine ion from Na2PO3F, each. These values were chosen so that each tablet would contain approximately the same amount of the ion

  • Neurobehavioral toxicity produced by sodium fluoride in drinking water of laboratory rats

    The effect of exposure to different concentrations of sodium fluoride (Na-F) for different durations on learning and memory tasks in rats (non-associative and associative learning) was assessed in our study. Three groups of fifteen pregnant Wistar female rats each, were administered Na-F in drinking water at one of three concentrations;

  • Cognitive enhancement effect of Ginkgo biloba extract on memory and learning impairments induced by fluoride neurotoxicity.

    The present work evaluated the neuroprotective functions of Ginkgo biloba extract (GBE) on cognitive and behavioural functions in fluoride intoxicated rats. Thirty male Wistar rats were randomly divided into 5 Groups (n=6 in each Group). Group 1 was Control that received water, Groups 2 to 5 were treated with 100

  • Fluoride & IQ: 67 Studies

    As of May 2020, a total of 75 studies have investigated the relationship between fluoride and human intelligence. Of these investigations, 67 studies have found that elevated fluoride exposure is associated with reduced IQ in humans, while over 60 animal studies have found that fluoride exposure impairs the learning and/or

  • Fluoride: Developmental Neurotoxicity.

    Developmental Neurotoxicity There has been a tremendous amount of research done on the association of exposure to fluoride with developmental neurotoxicity. There are over 60 studies reporting reduced IQ in children and several on the impaired learning/memory in animals. And there are studies which link fluoride to Attention Deficit Hyperactivity Disorder. Teaching

  • Fluoride Affects Learning & Memory in Animals

    An association between elevated fluoride exposure and reduced intelligence has now been observed in 65 IQ studies. Although a link between fluoride and intelligence might initially seem surprising or random, it is actually consistent with a large body of animal research. This animal research includes the following 45 studies (out

  • Fluoride's Effect on Fetal Brain

    The human placenta does not prevent the passage of fluoride from a pregnant mother's bloodstream to the fetus. As a result, a fetus can be harmed by fluoride ingested pregnancy. Based on research from China, the fetal brain is one of the organs susceptible to fluoride poisoning. As highlighted by the excerpts

  • Fluoride's Direct Effects on Brain: Animal Studies

    The possibility that fluoride ingestion may impair intelligence and other indices of neurological function is supported by a vast body of animal research, including over 40 studies that have investigated fluoride's effects on brain quality in animals. As discussed by the National Research Council, the studies have consistently demonstrated that fluoride, at widely varying concentrations, is toxic to the brain.
