High levels of lithium in tap water linked to lowered rates of dementia
(Medical Xpress)—A team of researchers from several institutions in Denmark has found what appears to be a link between the amount of lithium naturally present in tap water and dementia in the people that drink it. In their paper published in JAMA Psychiatry, the group describes how they tested tap water that reached approximately 800,000 people in Denmark and compared it with dementia rates to see if there might be any connection between the two. John McGrath with the University of Queensland and Michael Berk with Deakin University, both in Australia, offer an editorial piece in the same journal issue describing the work done by the team in Denmark and the possibility of adding lithium to drinking water to lower dementia rates.
