Aluminium and fluoride in tap water raises risk of dementia – latest research

New scientific research has revealed a greater risk of dementia in people drinking tap water in Scotland loaded with aluminium and fluoride.

The research concluded that higher levels of aluminium and fluoride were related to dementia risk in a population of men and women who consumed even relatively low drinking-water levels of both aluminium and fluoride.

The study led by Dr Tom Russ of the Alzheimer Scotland Dementia Research Centre at the University of Edinburgh and published in British Journal of Psychiatry, added: “Environmental risk factors for dementia are poorly understood. Aluminium and fluorine in drinking water have been linked with dementia but uncertainties remain about this relationship.

“In the largest longitudinal study in this context, we set out to explore the individual effect of aluminium and fluoride in drinking water on dementia risk. And as fluorine can increase absorption of aluminium, we also examined any synergistic influence on dementia.”

The research revealed that out of nearly 7,000 people covered by the study, 1,972 of them later developed dementia. And it showed the risk of dementia developing doubled in the quarter of the population living in areas with the highest concentrations of fluoride in the drinking water, compared to the lowest.
