At present, diagnosing people with Alzheimer’s relies on brain imaging or painful lumbar puncture
Blood tests for Alzheimer’s could be available on the NHS within five years, experts have said. Alzheimer’s Research UK and the Alzheimer’s Society have launched a £5 million project to bring simple tests to the health service, with the hope of speeding up diagnosis and reaching more people.
Pharmaceutical giants Roche and Eli Lilly have also announced they have joined forces to develop a blood test for Alzheimer’s disease. Some tests were already being used in private clinics in Hong Kong and the US, but UK charities said more work was needed to ensure tests were measuring the right combination of biomarkers.
“We need better, more scalable tests that are also accurate, and compare to current gold-standard methods.” She said “we’re sitting on the cusp of a new era of dementia treatments” but “the NHS doesn’t possess the required levels of diagnostic infrastructure to cope with this growing demand”. The new project – the Blood Biomarker Challenge – will work with researchers to pilot new blood tests in the NHS that can diagnose different forms of dementia earlier and more accurately. There is no suggestion as yet that the tests could be used for mass population testing.

Team finds new culprit in amyloid beta buildup and neurodegenerationResearchers at Weill Cornell Medicine have demonstrated how amyloid beta, a peptide associated with Alzheimer's disease, can interact with a protein receptor on immune cells in the brain. This triggers a reaction that damages blood vessels and causes neurodegeneration.
