A blood test could spot Alzheimer’s disease at the earliest stage and years before symptoms appear, studies in the US and Sweden suggest.
The test looks for tiny amounts of a protein which is elevated in people with the illness.
Investigators found measuring this protein, p-tau217, could predict Alzheimer’s dementia with 96% accuracy.
Experts say that with more research, it could be developed into a test doctors could offer to patients.
Currently, Alzheimer’s is diagnosed using a combination of memory tests and brain scans, once symptoms have already appeared.
The idea of a dementia blood test is not new, but these two latest studies give the clearest indication yet that a protein associated with Alzheimer’s disease could be used to diagnose people at a much earlier stage.
Early diagnosis is important because it could offer more opportunities to treat the disease.
