Per Philippa Roxby & Elena Bailey, in BBC News “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.

Most of the reason why we get dementia is down to things we cannot control, such as the genes we inherit from our parents and grandparents.

But 45% of our risk can be changed, according to international experts in the field, and can therefore be reduced."

The Lancet Commission on Dementia Prevention, Intervention, and Care published a report on July 31, 2024 with recommendations to reduce dementia risk in the world. While we can’t change our genes, we can definitely work on reducing our other risk factors.
