Abstract
Neurological symptomatology in the form of the syndrome of vegetative-vascular dysfunction, or the asthenovegetative syndrome with polyneuritic (sensory and vegetative) disorders was detected in 78.8% of patients with occupational fluorosis in preosteal and osteal stages. Clinical and physiological investigations of the nervous system (psycho-physiological procedures, EEG, chronaximetry) showed patients with fluorosis to exhibit disturbed higher nervous activity and dysfunction of subcorticalaxial nonspecific structures of the brain.

Developmental toxicity of sodium fluoride in rats
Despite the chronic exposure of the US population to fluoridated drinking water since the 1940s, existing studies have been judged inadequate to determine any potential reproductive or developmental hazard. This study was conducted to determine the effects of sodium fluoride (NaF) on foetal development. Sperm-positive female rats were given 0,

The effect of small quantities of fluorine on the human body
Clinical and physiological observations were made of school children in an endemic [area] where the fluorine content of water was within 1.6 mg/l. Stomatological examinations show that the prolonged use of drinking water containing these concentrations of fluorine causes among the children lesions of dental enamel of the I and

Inferring the fluoride hydrogeochemistry and effect of consuming fluoride-contaminated drinking water on human health in some endemic areas of Birbhum district, West Bengal
This research work is carried out to evaluate fluoride (F) hydrogeochemistry and its effect on the population of two endemic villages of Birbhum district, West Bengal. Fluoride concentration in drinking water varies from 0.33 to 18.08 mg/L. Hydrogeochemical evolution suggests that ion-exchange mechanism is the major controlling factor for releasing F

Chronic fluorine intoxication from drinking water
Summary The case of ? 35-year-old woman is described presenting stiffness and severe pain in the spine, gastric disturbances, stomatitis, paresthesias in legs and arms, especially in the u1nar nerve area, loss of mental acuity, visual disturbances and extreme general malaise. On1y ? few clear-cut objective findings were noted, namely: decreased muscular

Effects of high fluoride level on neonatal neurobehavioral development
The effects of excessive fluoride intake during pregnancy on neonatal neurobehavioral development and the neurodevelopment toxicity of fluoride were evaluated. Ninety-one normal neonates delivered at the department of obstetrics and gynecology in five hospitals of Zhaozhou County, Heilongjiang Province, China were randomly selected from December 2002 to January 2003. The

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.

Skeletal Fluorosis: The Misdiagnosis Problem
It is a virtual certainty that there are individuals in the general population unknowingly suffering from some form of skeletal fluorosis as a result of a doctor's failure to consider fluoride as a cause of their symptoms. Proof that this is the case can be found in the following case reports of skeletal fluorosis written by doctors in the U.S. and other western countries. As can be seen, a consistent feature of these reports is that fluorosis patients--even those with crippling skeletal fluorosis--are misdiagnosed for years by multiple teams of doctors who routinely fail to consider fluoride as a possible cause of their disease.

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: 68 Studies
As of February 2021, a total of 76 studies have investigated the relationship between fluoride and human intelligence. Of these investigations, 68 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
