Beneficial effects of Emblica officinalis on fluoride-induced toxicity on brain biochemical indexes and learning-memory in rats
AIMS: The present study was aimed to investigate the effects of Emblica officinalis against fluoride-induced alterations in the behavioral and biochemical abnormalities in rats. DESIGN: The healthy adult albino rats of Wistar strain (Rattus norvegicus) weighed 200-250 g were used for experiments. The animals were divided into three groups. Group I,

Trace element levels in drinking water and cognitive function among elderly Chinese
The relation between trace element levels in drinking water and cognitive function was investigated in a population-based study of elderly residents (n = 1,016) in rural China in 1996-1997. Cognitive function was measured using a Chinese translation of the Community Screening Interview for Dementia. A mixed effects model was used

Molecular mechanism of brain impairment caused by drinking-acquired fluorosis and selenium intervention
This study investigated the molecular mechanism of brain impairment induced by drinking fluoridated water and selenium intervention. Results showed that the learning and memory of rats in NaF group significantly decreased. Moreover, the number of apoptotic cells, the expression levels of Cytc mRNA and protein, and the expression levels of

Toxicity of fluoride: critical evaluation of evidence for human developmental neurotoxicity in epidemiological studies, animal experiments and in vitro analyses.
Recently, epidemiological studies have suggested that fluoride is a human developmental neurotoxicant that reduces measures of intelligence in children, placing it into the same category as toxic metals (lead, methylmercury, arsenic) and polychlorinated biphenyls. If true, this assessment would be highly relevant considering the widespread fluoridation of drinking water and

The impact of endemic fluorosis caused by the burning of coal on the development of intelligence in children.
Objective: To explore the effect of endemic fluorosis caused by coal burning on the level of intelligence in children. The Method: We randomly selected 20 school children from 4 areas between the ages of 8[1]12, whose characteristics fit the scope of our research. They were chosen from slight, moderate, and severe endemic

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 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
Note: See the Updated list of fluoride IQ studies at https://fluoridealert.org/researchers/fluoride-iq-studies/the-fluoride-iq-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

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.
