Abstract
Background: Curcumin (Cur), an active ingredient of turmeric is known to have multiple activities, including an antioxidant property and has been suggested to be useful in treatment of several neurological diseases.
Objective: To investigate the neuroprotective effects of Cur to mitigate the effect of the Fluoride (F) induced neurotoxicity in mice brain using the histological and the biochemical parameters.
Materials and Methods: Exposure of mice (30 days old male) to F (120 ppm) daily for 30 days.
Result and Discussion: Treatment with the F causes an increase in lipid peroxidation (LPO) and also increase in the neurodegenerative cells in the hippocampal sub-regions. Interestingly, co-treatment with Cur (30 mg/kg BW) with F (120 ppm) for 30 days results in significant decreases in LPO with a concomitant decrease in neurodegeneration as compared with those treated with F alone.
Conclusion: Our study reveals that Cur is useful in ameliorating degenerative effects of F in mice brain.

Attenuating effect of Vitamin E on the deficit of learning and memory of rats with chronic fluorosis: the mechanism may involve muscarinic acetylcholine receptors.
The protective role of vitamin E (Vit E) against neurotoxicity induced by fluorosis was investigated by using Sprague-Dawley (SD) rats fed with 50 ppm fluoride in drinking water for 10 months. Spatial learning and memory of rats were measured by the Morris water maze test; the expressions of M1 and

Effects of fluoride on the expression of NCAM, oxidative stress, and apoptosis in primary cultured hippocampal neurons.
The mechanisms underlying the neurotoxicity of endemic fluorosis still remain unknown. To investigate the expression level of neural cell adhesion molecules (NCAM), oxidative stress, and apoptosis induced by fluoride, the primary rat hippocampal neurons were incubated with 20, 40, and 80 mg/l sodium fluoride for 24 h in vitro. The

Suppression of mitochondrial oxidative phosphorylation and TCA enzymes in discrete brain regions of mice exposed to high fluoride: amelioration by Panax ginseng (Ginseng) and Lagerstroemia speciosa (Banaba) extracts
Chronic fluoride intoxication results in pathophysiological complications pertaining to soft tissues, called non-skeletal fluorosis. This study examined whether fluoride-induced alterations in selected parameters that are indicative of mitochondrial dysfunction accompany the toxic effects of fluoride in discrete brain regions in vivo and also explored the possibility of treatment with Ginseng

Combined impact of exercise and temperature in learning and memory performance of fluoride toxicated rats.
In previous studies, we investigated a link between high fluoride exposure and functional IQ deficits in rats. This study is an extension conducted to explore the combined influence of physical exercise and temperature stress on the learning ability and memory in rats and to assess whether any positive modulation could

Aluminum and fluoride impacts cortex and hippocampus structure in rats: protective role of resveratrol.
Metals such as aluminum and Fluoride have been implicated in the etiology of several neurodegenerative disorders . Resveratrol, a natural polyphenol, exerting a wide range of biological and pharmacological activities including its antioxidative properties against neurodegenerative disorders through its ability to lessen oxidative stress. Rats were divided in to 4

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'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: 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
