Abstract
On the basis of routine EEG, this article used mapping technologies to conduct research on the brain electrical activities of mentally retarded children in high-fluoride regions. Results showed that the O energy percentages in the central, parietal, occipital, and left temporal areas of the mentally retarded group were significantly higher than those of the normal control group. The a energy percentages in the central and occipital areas were significantly lower than those of the control group. These abnormal changes in brain electrical activities were closely related to the high-fluoride environment. The degree of damage of fluoride to brain functions can be intuitively and visually understood via brain mapping

Black berry juice attenuates neurological disorders and oxidative stress associated with concurrent exposure of aluminum and fluoride in male rats
The objective of this study was to assess the protective effect of black berry juice (BBJ) on the neurological disorders and oxidative stress induced by co-exposure to ALCL3 and NaF in male albino rats. Administration of either AlCl3 (200?mg/kg bw) or NaF (10?mg/kg bw) or both of them caused a

Protective role of tert-butylhydroquinone against sodium fluoride-induced oxidative stress and apoptosis in PC12 cells.
The neurotoxicity of fluoride is associated with oxidative stress due to imbalance between production and removal of reactive oxygen species (ROS). In contrast, induction of detoxifying and antioxidant genes through activation of NF-E2-related factor 2 (Nrf2) has been implicated in preventing oxidative stress and apoptosis in neurodegenerative diseases. The present

[Effects of sodium fluoride on the activity of Ca2+Mg(2+)-ATPase in synaptic membrane in rat brain].
Effects of sodium fluoride on Ca2+Mg(2+)-ATPase activity of synaptic membrane in rat brain were studied with in vitro or in vivo methods. Concentrations of sodium fluoride of 0.3, 1.6, 8.0, 20.0 and 40.0 mmol/L can significantly inhibit the activity of the enzyme with proportions of 6.6%, 18.0%, 41.0%, 55.5% and

Brain lipid peroxidation and antioxidant systems of young rats in chronic fluoride intoxication
A study was made of the effect of fluoride on oxidative stress in rats during their early stages in life. Wistar albino rats were exposed to 30 ppm and 100 ppm fluoride (from sodium fluoride) in drinking water during the last one week of intrauterine life and then up to

Ameliorative effects of oleanolic acid on fluoride induced metabolic and oxidative dysfunctions in rat brain: experimental and biochemical studies
Beneficial effects of oleanolic acid on fluoride-induced oxidative stress and certain metabolic dysfunctions were studied in four regions of rat brain. Male Wistar rats were treated with sodium fluoride at a dose of 20 mg/kg b.w./day (orally) for 30 days . Results indicate marked reduction in acidic, basic and neutral

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'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: 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
