Two new dementia risks identified by major report
Treating failing eyesight and high cholesterol are two new ways to lower the risk of dementia developing, a major report suggests.
Scientists have now identified 14 health issues which, if reduced or eliminated, could theoretically prevent nearly half of dementias in the world.
Middle-aged people and poorer countries have most to gain from targeting these risk factors, the Lancet Commission's latest report on the topic.
It predicts that the number of people living with dementia could more than double to 153 million by 2050.
