New Study Raises Questions About How Fluoride Affects Children ’ s Development

(CNN) — Water fluoridation has been hailed by the US Centers for Disease Control and Prevention as one of the top great public health achievements of the 20th century, but a new study raises questions about its role as a potential neurotoxin in utero. The study, published in the journal JAMA Pediatrics on Monday, found that increased levels of fluoride exposure during pregnancy were associated with declines in IQ in children. Previous research has made similar findings, but this is the first such study to evaluate the effect of fluoride on populations receiving what the US Public Health Service considers optimal levels of 0.7 milligrams of fluoride per liter of drinking water, such as in the United States and Canada. The authors of the new study assessed 601 Canadian mother and child pairs, tracking the fluoride exposure of 512 of the mothers by looking at the average concentration of fluoride in urine samples taken throughout their pregnancies as a proxy for prenatal fluoride exposure. The authors also estimated the mothers’ daily fluoride intake by surveying their beverage intake, including tap water. Between the ages of 3 and 4, all children born from the studied mothers were tested for IQ. The authors found that for each additional 1 milligram per liter in concentration of fluoride in a mother’s urine, there was a 4.5-point drop in IQ in males. The study did not find such a significant association in female children, nor did it examine why boys were more...

Abstract Preeclampsia is a dangerous hypertensive disorder of pregnancy with known links to negative child health outcomes. Here, we review epidemiological and basic neuroscience work from the past several decades linking prenatal preeclampsia to altered neurodevelopment. This work demonstrates increased rates of neuropsychiatric disorders [e.g., increased autism spectrum disorder, attention deficit hyperactivity disorder (ADHD)] in children of preeclamptic pregnancies, as well as increased rates of cognitive impairments [e.g., decreased intelligence quotient (IQ), academic performance] and neurological disease (e...

Abstract Autism is a neuropathology characterized by behavioral disorders. Considering that oxidative stress is involved in the pathophysiology of this disease, we evaluated the effects of quercetin, a flavonoid with antioxidant and neuroprotective properties, in an experimental model of autism induced by valproic acid (VPA). Twelve pregnant female rats were divided into four groups (control, quercetin, VPA, VPA+quercetin). Quercetin (50 mg/kg) was administered orally to the animals from gestational days 6.5 to 18.5, and VPA (800 mg/kg) was administered orally in a single dosage on gestational day 12.5. Behavioral...

This study investigated whether antenatal exposure to antidepressants (ADs) increases the risks of autism spectrum disorders (ASD), attention deficit/hyperactivity disorders (ADHD), schizophrenia and other mental illnesses, and cognitive and developmental deficits in infants or preschool children. PubMed, EMBASE, BIREME/BVS databases were searched to identify studies examining associations of ADs in pregnancy with neurodevelopmental and psychiatric disorders. Twenty studies addressed ASD and/or ADHD risks while 30 focused on developmental and cognitive deficits in infants or preschool children. Most studies detected no ass...

Autism spectrum disorder is a neurodevelopmental disorder characterized by reduced social interactions, impaired communications, and stereotypic and repetitive behavior with different degrees of severity. The etiology of autism spectrum disorder is unknown, although the interaction of genetic and environmental factors is believed to play a fundamental role in the process. The main aim of this narrative review is to discuss the current knowledge about the interrelationships between vitamin D deficiency during pregnancy and autism spectrum disorder development. Literature analysis showed that vitamin D supplementation during...
