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.

Sirt3-mediated mitochondrial dysfunction is involved in fluoride-induced cognitive deficits.
Highlights Fluoride induces cognitive deficits in mice. Fluoride exposure results in neural/synaptic injury in the hippocampus of mice. Mitochondrial dysfunction contributes to neural/synaptic alternations. Inhibition of Sirt3 is involved in the fluoride-evoked mitochondrial abnormalities. Abstract Excessive fluoride is capable of inducing cognitive deficits, but the mechanisms remain elusive. This study aimed

Evaluation of fluoride-induced oxidative stress in rat brain: a multigeneration study.
Multigenerational evaluation was made in rats on exposure to high fluoride (100 and 200 ppm) to assess neurotoxic potential of fluoride in discrete areas of the brain in terms of lipid peroxidation and the activity of antioxidant enzyme system. The rats were given fluoride through drinking water (100 and 200 ppm) and

Evaluation of Metformin and Dehydrozingerone against fluorosis induced neurodevelopmental toxicity in preclinical models.
Background: Inorganic fluoride is widely used in dental practices to treat problems like dental caries and also to prevent bone related issues. It has been reported that exposure to excess amounts of fluoride either through drinking water or other sources impairs vital functions of the body and can

The analog of Ginkgo biloba extract 761 is a protective factor of cognitive impairment induced by chronic fluorosis.
Ginkgo biloba extract EGb761 is widely used to treat patients with learning and memory impairment in Alzheimer's disease and Parkinson's disease in China. However, it is not yet clear whether the analog of EGb761 (EGb) has a protective effect on the learning and memory damage induced by chronic fluorosis. In

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

Fluoride & Oxidative Stress
A vast body of research demonstrates that fluoride exposure increases oxidative stress. Based on this research, it is believed that fluoride-induced oxidative stress is a key mechanism underlying the various toxic effects associated with fluoride exposure. It is also well established that fluoride's toxic effects can be ameliorated by exposure

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
