Abstract
Rats given sodium fluoride at 10 mg/kg daily by the intraperitoneal route were more sensitive to the convulsant action of strychnine and pentylenetetrazol and to electroshock. This increase in sensitivity to CNS stimulation was observed also in two other groups of rats which were given a diet with added sodium fluoride amounting to 7 and 70 parts per million in terms of fluoride. Prolonged treatment with fluoride also lengthened the sleeping time induced by pentobarbital and increased the protective effect of diphenylhydantoin against electroshock. The increase in sensitivity to some CNS-active agents in the fluoride-treated rats disappeared after these rats were given the control diet for 2 weeks,

Investigation on the role of Spirulina platensis in ameliorating behavioural changes, thyroid dysfunction and oxidative stress in offspring of pregnant rats exposed to fluoride.
Highlights Sodium fluoride exposure from pregnancy to lactation induces thyroid toxicity. This can affect neurodevelopment and induce behavioural changes. Spirulina platensis role in reversing fluoride-induced toxicity was ascertained. Significant protection was exerted by Spirulina The study investigated the role of Spirulina platensis in reversing sodium fluoride-induced thyroid, neurodevelopment and oxidative alterations

Components of Drinking Water and Risk of Cognitive Impairment in the Elderly.
The relation between aluminum, fluorine, calcium, and pH in drinking water and the risk for cognitive impairment was studied using data collected in 1988-1989 in a population-based survey of 3,777 French men and women aged 65 years and older (the Paquid study). Cognitive impairment was defined as a score lower

Interplay of ROS and behavioral pattern in fluoride exposed Drosophila melanogaster.
Highlights NaF exposure increases mortality and changes male-female ratio in Drosophila. NaF treatment alters the activities endogenous antioxidant enzymes. Chronic sub-lethal NaF exposure causes increased oxidative damage. NaF decreases brain cell viability and increases DNA damage. NaF exposure alters selected behavioral pattern in Drosophila melanogaster. Reactive oxygen species (ROS) is

Effect of NaF on albino female mice with special reference to behavioral studies and ACh and AChE levels
The present study investigates the effect of the Sodium Fluoride (NaF) on Wistar Albino mice. The animals have been divided into three batches each containing five individuals among which 1 batch served as control while, remaining two batches were treated with 5 and 10ppm respectively. After completion of exposure, the

Effect of fluorosis on mice learning and memory behaviors and brain SOD activity and MDA content
Objective: Explore the brain mechanism of the effect of fluorosis on learning and memory behavior. Method: A method combining behavioral observation and biochemical testing was used to study the effects of long-term drinking different concentrations of sodium fluoride on mouse learning and memory behavior and changes in content of brain

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

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 78 studies reporting reduced IQ (75 studies with children and 3 studies with adults) and several on the impaired learning/memory in animals. And there are studies which link

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
