Researchers from Stanford might have found a biological marker for Alzheimer’s disease via a simple blood test. This is exciting news given that it might predict the onset of the disease several years before the symptoms begin. The procedure involves examining 18 key proteins in the blood that are typical in Alzheimer’s patients. Preliminary tests have been 90% accurate at detecting the disease. Dr Susanne Sorensen, of the Alzheimer’s Society, said that “Early diagnosis is essential if we are ever to develop treatments that can change the course or halt the progression of dementia rather than just treat the symptoms.”
