Alzheimer’s blood test ‘one step closer’

No icon Good News

Health Desk- 4 August, 2019: Researchers say they can accurately identify people on track to develop Alzheimer's disease before symptoms appear, which could help the progress of drug trials.

US scientists were able to use levels of a protein in the blood to help predict its build-up in the brain.

UK experts said the results were promising - and a step towards a reliable blood test for Alzheimer's to speed up dementia research.

But larger studies were needed first.

Alzheimer's is the most common cause of dementia, affecting more than 520,000 people in the UK, mostly over-65s, and millions around the world. There are currently no treatments to halt the disease.

Researchers from Washington University School of Medicine, in St Louis, Missouri, writing in Neurology, measured levels of one protein, called amyloid beta, in the blood of 158 adults aged over 50 to see if this matched levels found in brain scans.

Dr Sara Imarisio, from Alzheimer's Research UK, said: "Improving the accuracy of blood tests has long been a goal for researchers and using additional information about genetic risk to bolster a test like this is an encouraging step forward.
