fluoride in drinking water and the prevalence of Attention Deficit Hyperactivity Disorder in the United States.

New research shows there is a strong connection between increased levels of fluoride in drinking water and the prevalence of Attention Deficit Hyperactivity Disorder in the United States.

The study titled Exposure to fluoridated water and attention deficit hyperactivity disorder prevalence among children and adolescents in the United States: an ecological association study published earlier this year in the journal Environmental Health discovered that a one per cent increase in artificial fluoridation prevalence in 1992 was linked to roughly 67,000 to 131,000 extra ADHD diagnoses from 2003 to 2011. The research went back to fluoridation in 1992, emphasizing the harmful effects which exist some two decades later.

The team of researchers analysed information from the U.S. National Survey of Children’s Health related to children aged between four gathered over several years. A couple of months after the study was released the U.S. Department of Health and Human Services announced they would reduce the amount of fluoride in drinking water; the recommended range is currently of 0.7 to 1.2 milligrams...........
