Abstract
The aim of this study was to evaluate the effects of fluoride on anxiety and depression in mice. Control and study groups were formed with ten 4-month-old male Swiss mice in each group. For 90 days, mice in the control group were given drinking water containing 0.3 ppm fluoride while the study group was given water with 40 ppm fluoride. Tail suspension was not significantly different between the study and the control groups. In an open field test, however, the number of defecations was higher in the study group, and transitions, rearing, and grooming activities were less frequent. Under these conditions, fluoride appeared to have no antidepressant effect in mice but rather an anxiety stimulating effect.

Exposure to fluoridated public water supplies and child health and behaviour.
The relationship between duration of exposure to fluoridated public water supplies and measures of child health and behaviour was studied for a birth cohort of Christchurch children. This study showed no association between exposure to fluoridated water and a large range of measures of child health and behaviour taken during

Use of the Rey-Osterrieth Complex Figure Test for neurotoxicity evaluation of mixtures in children.
The aim of this study was to assess the value of the children's version of the Rey-Osterrieth Complex Figure Test as a screening test in a population exposed to different mixtures of neurotoxicants. Copy and Immediate Recall scores were evaluated through the test. Children were recruited from three sites; an

Experimental pharmacological researches regarding the influence of sodium fluoride in allopathic and homeopathic doses in central nervous system's performances. A correlation between behavioral response in classic maze test and morphological aspects of cerebral cortex
The influence of fluorine administration on central nervous system’s (CNS) performances in female mice treated during gestation with two distinct doses of sodium fluoride (NaF): 0.25 mg and 0.50 mg. The research extended also to offspring (generation 1 – F1), treated with NaF in allopathic (0.25 and 0.50 mg), homeopathic

Behavioral and general effects of subacute oral arsenic exposure in rats with and without fluoride
Consequences of oral arsenic and fluoride exposure on motor behavior and general toxicity were modeled in young adult male rats which received sodium (meta)arsenite (10 mg/kg-b.w.), sodium fluoride (5 mg/kg-b.w.), and their combination by gavage, once daily, 5 days a week for 6 weeks. After 6 weeks, 6 animals per group were dissected, while the

Fluoride exposure during development affects both cognition and emotion in mice
Highlights The developmental fluoride exposure to mice affects their emotional behaviors. The developmental fluoride declines both spatial and non-spatial cognition of mice. The high fluoride reduces the exercise tolerance of mice. Previous studies have suggested that sodium fluoride (NaF) may have adverse effects on neurodevelopment. In the present study, we evaluated

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 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 & 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
