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

Fluoride Induces Neuroinflammation and Alters Wnt Signaling Pathway in BV2 Microglial Cells.
Fluoride is a common element in nature and our daily life, and excessive intake of this element can cause fluorosis and irreversible brain damage. The toxic effects of fluoride on the central nervous system may be attributed to the release of inflammatory cytokines and ROS. GSK3B is a key protein

Systematic impacts of fluoride exposure on the metabolomics of rats.
Highlights The risk of chronic endemic fluorosis exists in many countries and regions. Comprehensive metabolomic analysis was used to study the effects of fluoride. Multivariate statistics were used to detect metabolite profile changes. Fluoride exposure caused amino acid, fatty acid, and energy metabolism disorders. Fluoride exposure caused oxidative stress,

A correlation between serum vitamin, acetylcholinesterase activity and IQ in children with excessive endemic fluoride exposure in Rajasthan, India
Fluoride is widely distributed in nature and a direct source of adverse health effects in human populations. Fluoride poisoning attributed by long-term exposure to high levels of fluoride [is] called fluorosis. The present study was carried out among 9-14 years old school children of Dausa district, Rajasthan India. The subjects

Cognitive Decline of Rats with Chronic Fluorosis Is Associated with Alterations in Hippocampal Calpain Signaling.
The study was designed to evaluate an influence of excessive fluoride (F-) intake on cognitive capacities of adult rats and on proteins of memory-related calpain signaling in hippocampus. Control animals were given water with natural F- content of 0.4 ppm; rats from other groups consumed the same water supplemented with 5,

Chronic fluoride exposure alters antioxidant enzymes in rat brain and intestine
Background: Low Fluoride use has been advocated as a therapeutic agent for delaying tooth decay however, high fluoride exposure has been associated with behavioral changes, low IQ, and altered brain functions and development. Although Fluoride generally does not generate free radicals but is still implicated in free radical associated damage

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: 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
