Abstract
The epiphysis is a gland containing firm extracellular bodies (brain sand) the number of which increases with age. Microscopy and roentgen microtomography showed that in some cases of schizophrenia the amount of brain sand decreases. In parallel, cytoplasm of pinealocytes appears to contain concrements of a new type–irregular hollow spheres of 0.1-1.5 microm in size. They may contain fluoride. Typical hydroxyapatite retaining organic stroma may dissolve starting from the center both in health and schizophrenia.
NOTE FROM FAN: The epiphysis is another term for pineal.

Fluoride Exposure and Neurodevelopmental Outcomes Among Children in the United States: A pilot study.
Background/Aim: Developmental neurotoxicity of fluoride has been demonstrated in animal studies. Additionally, fluoride exposure during prenatal development, infancy, middle-to-late childhood and adolescence has been associated with poorer neurodevelopmental outcomes among children in Mexico and/or Canada. However, potential impacts of chronic low-level fluoride exposure in early childhood on brain structure and

Perinatal exposure to sodium fluoride with emphasis on territorial aggression, sexual behaviour and fertility in male rats.
Territorial aggression, sexual behaviour and fertility parameters were evaluated at adulthood of male rats previously exposed to different concentrations of sodium fluoride (Na-F) at their gestation, lactation and postweaning period till maturation. Sixty weanling male Wistar rats were received Na-F via their dams from second trimester of their pregnancy onward

Use of the Rey-Osterrieth Complex Figure Test for neurotoxicity evaluation of mixtures in children.
The aim of this study was to assess the value of the children's version of the Rey-Osterrieth Complex Figure Test as a screening test in a population exposed to different mixtures of neurotoxicants. Copy and Immediate Recall scores were evaluated through the test. Children were recruited from three sites; an

Aspects of nervous system affections in occupational fluorosis.
Neurological symptomatology in the form of the syndrome of vegetative-vascular dysfunction, or the asthenovegetative syndrome with polyneuritic (sensory and vegetative) disorders was detected in 78.8% of patients with occupational fluorosis in preosteal and osteal stages. Clinical and physiological investigations of the nervous system (psycho-physiological procedures, EEG, chronaximetry) showed patients with

Investigation on the role of Spirulina platensis in ameliorating behavioural changes, thyroid dysfunction and oxidative stress in offspring of pregnant rats exposed to fluoride.
Highlights Sodium fluoride exposure from pregnancy to lactation induces thyroid toxicity. This can affect neurodevelopment and induce behavioural changes. Spirulina platensis role in reversing fluoride-induced toxicity was ascertained. Significant protection was exerted by Spirulina The study investigated the role of Spirulina platensis in reversing sodium fluoride-induced thyroid, neurodevelopment and oxidative alterations

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 Affects Learning & Memory in Animals
An association between elevated fluoride exposure and reduced intelligence has now been observed in 65 IQ studies. Although a link between fluoride and intelligence might initially seem surprising or random, it is actually consistent with a large body of animal research. This animal research includes the following 45 studies (out

Fluoride & IQ: 68 Studies
As of February 2021, a total of 76 studies have investigated the relationship between fluoride and human intelligence. Of these investigations, 68 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
