Dementia with Lewy bodies

Dementia with Lewy bodies is the third most common cause of dementia.

Age is the biggest known risk factor for the development of dementia with Lewy bodies. Researchers are working hard to identify other factors that may be involved.

Recent studies have found several genes linked to a higher risk of DLB, including a known risk gene for Alzheimer’s. While these discoveries tell us about the biology of DLB, having one of these risk genes does not mean you will definitely develop the disease and there is no test available for them on the NHS.
