Abstract
The impacts of environmental and occupational exposure to ionizing radiation and to long-term intake of high levels of fluoride have caused health problems and increasingly alarming in recent years. Fish oil omega-3 (polyunsaturated fatty acids essential fatty acids) is found in the highest concentrations in fish oil, claim a plethora of health benefits. The objective of the present study was to evaluate the role of fish oil rich in omega-3 fatty acids on sodium fluoride (NaF) and or gamma (?) rays in inducing neurological and biochemical disturbances in rat’s brain cerebral hemispheres. The results revealed that whole body exposure to ?- radiation at 6 Gy applied as fractionated doses (1.5 Gy x 4 times) and/or chronic receipt of NaF solution (0.13 mg/Kg/day) for a period of 28 days, significantly increased brain fluoride and calcium content, decreased level of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) and induced brain oxidative stress which led to neurotransmitters dysfunction.
Supplementation of treated rats with fish oil, via gavages, at a dose of 400 mg/kg body wt has significantly modulated oxidative stress and neurotransmitters alterations. It could be concluded that EPA and DHA, found in fish oil, could possibly protect brain from damaging free radicals and consequently minimize the severity of brain biochemical disturbances

Mitigating role of quercetin against sodium fluoride-induced oxidative stress in the rat brain
CONTEXT: Quercetin is a well known aglycone flavonoid that is widely found in different food sources. OBJECTIVE: In this study, the in vivo neuroprotective potential of quercetin against sodium fluoride-induced oxidative stress was evaluated. MATERIALS AND METHODS: Wistar rats were divided into five treatment groups and then subjected to daily

Neuroprotective activity of Matricaria recutita against fluoride-induced stress in rats.
CONTEXT: Oxidative stress plays a key role in pathophysiology of many neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and so on. Although Matricaria recutita L. (Asteraceae), German chamomile, is traditionally used for central nervous system (CNS)-related diseases, its antistress properties have received little attention. OBJECTIVE: The present study evaluated the

Protective role of gallic acid on sodium fluoride induced oxidative stress in rat brain
Gallic acid is known as a potent antioxidant active compound of the edible and medicinal plant Peltiphyllum peltatum. The main objective of this study was to evaluate the neuroprotective effects of gallic acid against sodium fluoride induced oxidative stress in rat brain. Gallic acid (10 and 20 mg/kg) and vitamin C

Oxidative stress might be a mechanism connected with the decreased alpha 7 nicotinic receptor influenced by high-concentration of fluoride in SH-SY5Y neuroblastoma cells
The possible mechanism concerning decreased alpha 7 nicotinic acetylcholine receptor (nAChR) influenced by fluorosis was investigated. SH-SY5Y cells were exposed to fluoride within the range of 0.05-5 mM [corrected] or ferrous iron (1-100 mM) [corrected] a free radical inducer. The levels of alpha 7 nAChR expression, lipid peroxidation and protein

Neuroprotective effect of ascorbic acid and ginkgo biloba against fluoride caused neurotoxicity
Excessive consumption of fluoride through drinking water or other sources lead to skeletal and dental fluorosis. According to the world health organization 23 nations are facing the problem of fluorosis. In the recent past researchers describe the non-skeletal fluorosis where soft tissues and major organs are the victims of fluoride

Nutrient Deficiencies Enhance Fluoride Toxicity
It has been known since the 1930s that poor nutrition enhances the toxicity of fluoride. As discussed below, nutrient deficiencies have been specifically linked to increased susceptibility to fluoride-induced tooth damage (dental fluorosis), bone damage (osteomalacia), neurotoxicity (reduced intelligence), and mutagenicity. The nutrients of primary importance appear to be calcium,

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

Kidney Patients Are at Increased Risk of Fluoride Poisoning
It is well established that individuals with kidney disease are susceptible to suffering bone damage and other ill effects from low levels of fluoride exposure. Kidney patients are at elevated risk because when kidneys are damaged they are unable to efficiently excrete fluoride from the body. As a result, kidney patients

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 & IQ: 67 Studies
As of May 2020, a total of 75 studies have investigated the relationship between fluoride and human intelligence. Of these investigations, 67 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
