People with higher levels of lithium in their drinking water appear to have a lower risk of developing dementia, say researchers in Denmark.
Lithium is naturally found in tap water, although the amount varies.
The findings, based on a study of 800,000 people, are not clear-cut. The highest levels cut risk, but moderate levels were worse than low ones.
Experts said it was an intriguing and encouraging study that hinted at a way of preventing the disease.
The study, at the University of Copenhagen, looked at the medical records of 73,731 Danish people with dementia and 733,653 without the disease.
Tap water was then tested in 151 areas of the country.
