Age is the biggest known risk factor for the development of Dementia with Lewy bodies.
We know that conditions like high blood pressure and high cholesterol are risk factors for other causes of dementia such as Alzheimer's disease. There is some evidence to suggest this may also be true for DLB. If you have concerns, you can speak to your doctor about managing these conditions.
Recent studies have found several genes linked to a higher risk of DLB, including a known risk gene for Alzheimer’s. While these discoveries help us to understand the biology of DLB, having one of these risk genes does not mean you will definitely develop the disease. There is no test available on the NHS for these genes.
