Abstract
The aim of this study was to evaluate the effects of fluoride on anxiety and depression in mice. Control and study groups were formed with ten 4-month-old male Swiss mice in each group. For 90 days, mice in the control group were given drinking water containing 0.3 ppm fluoride while the study group was given water with 40 ppm fluoride. Tail suspension was not significantly different between the study and the control groups. In an open field test, however, the number of defecations was higher in the study group, and transitions, rearing, and grooming activities were less frequent. Under these conditions, fluoride appeared to have no antidepressant effect in mice but rather an anxiety stimulating effect.

Effect of NaF on albino female mice with special reference to behavioral studies and ACh and AChE levels
The present study investigates the effect of the Sodium Fluoride (NaF) on Wistar Albino mice. The animals have been divided into three batches each containing five individuals among which 1 batch served as control while, remaining two batches were treated with 5 and 10ppm respectively. After completion of exposure, the

Evaluation of standardized Bacopa monniera extract in sodium fluoride-induced behavioural, biochemical, and histopathological alterations in mice
Effect of standardized Bacopa monniera (BM; family: Scrophulariaceae) extract (100 and 300 mg/kg) against sodium fluoride (NaF; 100 and 200 ppm)-induced behavioural, biochemical, and neuropathological alterations in mice was evaluated. Akinesia, rotarod (motor coordination), forced swim test (depression), open field test (anxiety), transfer latency (memory), cholinesterase (ChE), and oxidative stress

Prenatal Fluoride Exposure and Autism Spectrum Disorder-Like Behaviors in a Sample of Canadian Preschool Aged Children: The MIREC Study.
BACKGROUND AND AIM: A growing body of evidence indicates that prenatal exposure to fluoride is neurotoxic to child development. However, epidemiologic research examining fluoride’s effect on autism spectrum disorder (ASD) is lacking. Our aim was to examine the association of prenatal fluoride exposure with ASD-like behaviors in a sample of

Gut microbiota perturbations and neurodevelopmental impacts in offspring rats concurrently exposure to inorganic arsenic and fluoride.
Many “hot spot” geographic areas across the world with drinking water co-contaminated with inorganic arsenic (iAs) and fluoride (F-), two of the most common natural contaminants in drinking water. Both iAs and F- are known neurotoxins and affect neurodevelopment of children. However, very few studies have investigated the neurodevelopmental effects

Sodium fluoride affects zebrafish behaviour and alters mRNA expressions of biomarker genes in the brain: Role of Nrf2/Keap1
Highlights Sodium fluoride (NaF) treatment changed the behaviour of zebrafish. Expression of antioxidant genes was upregulated. Expression of Nrf2 and its related genes were also altered. Results indicated that Nrf2 plays a significant role in NaF induced neurotoxicity. Sodium fluoride (NaF), used as pesticides and for industrial purposes are deposited

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: 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 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
