  • The antioxidant system enzymes’ activity in rats’ brain, intoxicated with sodium fluoride in subtoxic doses.

    The aim of the study was to assess the activity of enzymes in the antioxidant system in the brain of rats subjected to intoxication with sodium fluoride in subtoxic doses. Methods. The studies were conducted on sexually mature Wistar rats weighing 180-220 g, subjected to oral exposure by means of a

  • [Effects of high fluoride and low Iodine on learning-memory and TchE of brain in offspring rats].

    Objective To study the effect of high level fluoride and low level iodine on learning-memory in offspring rats and possible mechanism. Methods Thirty-two Wistar rats were randomly divided into four groups each of eight (female:male=(3:1).) The rats were treated with high fluoride (100 and 150 mg NaF/L), low iodine (0.0855 mg/kg),

  • Effects of fluoride on synapse morphology and myelin damage in mouse hippocampus

    Highlights Fluoride induced myelin damage in mouse hippocampus. Fluoride shortened the synaptic cleft and thickened the postsynaptic density. Fluoride altered the expressions of CREB, BDNF, and NCAM in hippocampus. To investigate the fluoride-induced neurotoxicity on mice hippocampus, healthy adult mice were exposed to 25, 50, and 100 mg NaF/L for 60 days.

  • Protective effect of resveratrol against neuronal damage through oxidative stress in cerebral hemisphere of aluminum and fluoride treated rats.

    Aluminum has no defined biological function and it is potentially involved in the pathogenesis of neurodegenerative disorders. Furthermore, the presence of fluoride causes more aluminum to accumulate in the brain, resulting in increased neuronal damage. In recent years, resveratrol through its ameliorative effects was found to be a neuroprotectant. This

  • Co-exposure to arsenic and fluoride on oxidative stress, glutathione linked enzymes, biogenic amines and DNA damage in mouse brain.

    We studied the effects of combined exposure to arsenic and fluoride on (i) brain biogenic amines, oxidative stress and its correlation with glutathione and linked enzymes; (ii) alterations in the structural integrity of DNA; and (iii) brain and blood arsenic and fluoride levels. Efficacy of alpha-tocopherol in reducing these changes

  • Fluoride & IQ: 69 Studies

    As of June 2021, a total of 77 studies have investigated the relationship between fluoride and human intelligence. Of these investigations, 69 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'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.

  • 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
