Researchers develop diagnostic tool to predict individual risk of Alzheimer's ANI | Updated: May 25, 2021 16:10 IST Lund [Sweden], May 25 (ANI): During a recent study, researchers at Lund University in Sweden developed an algorithm that combines data from a simple blood test and brief memory tests, to predict with greater accuracy who will develop Alzheimer's disease in the future. The findings have been published in the journal Nature Medicine. Approximately 20-30 per cent of patients with Alzheimer's disease are wrongly diagnosed within specialist healthcare, and diagnostic work-up is even more difficult in primary care. Accuracy can be significantly improved by measuring the proteins tau and beta-amyloid via a spinal fluid sample, or PET scan. However, those methods are expensive and only available at a relatively few specialized memory clinics worldwide. Early and accurate diagnosis of AD is becoming even more important, as new drugs that slow down the progression of the disease will hopefully soon become available.
