Dementia is the UK’s biggest killer and early and accurate diagnoses have never been more important. Blood-based biomarkers offer a promising, cost-effective and less invasive way of detecting Alzheimer's disease so it’s encouraging to see momentum in this area.

Earlier diagnosis unlocks access to treatments, support and help sooner. This study suggests blood tests could help detect Alzheimer’s disease in people in their early 60s – a group largely overlooked in previous research, which focused on older adults.  While we’re not yet at the point of screening people before symptoms appear, work like this suggests this may be a reality in the future.

By looking at these biomarkers in a more diverse population, the study made an important step in understanding the potential use of these blood tests for everyone. However, more research is still needed to explore how results may differ depending on a person’s race, sex and genetics.

Innovative approaches like this and the Blood Biomarker Challenge – led by Alzheimer’s Society, Alzheimer’s Research UK with Postcode Lottery funding – are critical to bringing blood tests for dementia to the NHS in the next five years.
