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.

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

[Effect of lycopene on oxidative stress and neurobehavior in mouse exposed to drinking water fluorosis].
Objective To investigate the relationship between lycopene exposure and neurobehavior and its mechanism in mouse exposed to drinking water fluorosis. Methods Sixty adult mice were randomly divided into six groups (ten animals in each group) : control group, lycopene group, sodium fluoride (NaF) group, NaF + low, medium, high dose lycopene groups.

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

Fluoride exposure during pregnancy and lactation triggers oxidative stress and molecular changes in hippocampus of offspring rats.
Highlights Fluoride exposure indirectly increased the levels of F in the offspring's plasma. Fluorine exposure promoted biochemical imbalance in the offspring's hippocampus. The 10 mgF/L and 50 mgF/L groups showed an overexpression of the neurotrophin BDNF. In exposed groups modulation of the proteomic profile of the offspring. Proteins associated

Fisetin prevents fluoride- and dexamethasone-induced oxidative damage in osteoblast and hippocampal cells
Fluoride intoxication and dexamethasone treatment produce deleterious effects in bone and brain. The aim of this study was to evaluate the effect of fluoride (F) and dexamethasone (Dex) co-exposure on oxidative stress and apoptosis in osteoblast-like MC3T3-E1 and hippocampal HT22 cell lines. Co-exposure to F and Dex resulted in a

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

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 & 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
