Abstract
In order to investigate the relationship between fluoride (F) in drinking water and children’s intelligence quotient (IQ), 39 9–12-year-old children in West Azerbaijan, were selected and their IQ measured using the Iranian version of the RB Cattell test. The study cases were 19 children living in a high-drinking water F region (3.94 mg F/L), and the control group was 20 children in a low-drinking water F region (0.25 mg F/L). The results showed that, the mean IQ of children living in the high-drinking water F region was lower (81.21±16.17) than that of children in the low-drinking water F region (104.25±20.73, p=0.0004). There is a significant linear trend for children in the high-drinking water F region to have a lower IQ (p=0.0067)

The effect of high fluoride exposure on the level of intelligence in children.
Objective: Investigate the effect of high fluoride exposure on the level of intelligence in children. Method: In May 2006, 42 children from a high endemic fluorosis group and 37 children from the control area (who have been consuming low-fluoride water after water improvement schemes) were chosen for the test. They are all

The effect of high levels of arsenic and fluoride on the development of children’s intelligence.
In the fields of toxicology, histology, physiology and biochemistry, numerous research and reports have already been conducted on the poisonous effect of arsenic poisoning, fluoride poisoning, as well as the combined effect of arsenic and fluoride poisoning. Progress has been made likewise in relevant medical treatment, clinical diagnosis and water clean-up prevention

The effects of high levels of fluoride and iodine on intellectual ability and the metabolism of fluoride and iodine.
The authors carried out a study on the intellectual abilities and fluoride/iodine metabolism of children living in a high fluoride-high iodine area. Among the results: the percentage of the general population living in this fluoride/iodine-contaminated region that suffered from goiter (clinical thyroid enlargement) was 3.8%, the rate of children already showing some thyroid

Investigation on children’s growth and development under long-term fluoride exposure
Objective To study the influence on children’s growth by long-term high fluoride exposure. Methods Case group was selected in high fluoride areas and control group was selected in non-high fluoride areas. The difference of children’s growth levels were analyzed between 2 groups. Results The IQ of case group was significantly lower than that of control

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 & IQ: 76 Studies
• As of July 18, 2022, a total of 85 human studies have investigated the relationship between fluoride and human intelligence. • Of these investigations, 76 studies have reported that elevated fluoride exposure is associated with reduced IQ in humans. • The studies which reported an association of reduced IQ with exposure

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.
