A SIMPLE, finger prick blood test, not so different from what people with diabetes do every day, shows promise in the ability to detect Alzheimer's disease, according to research reported for the first time today at the Alzheimer's Association International Conference 2023, in Amsterdam, Netherlands, and online.
Researchers set out to create a simple detection test via finger prick collection to measure key Alzheimer's-related biomarkers including neurofilament light, glial fibrillary acidic protein, and phosphorylated tau (p-tau181 and 217).
The study found that when compared with primary care physicians who correctly identified the presence of Alzheimer's-related changes in approximately 55% of the cases, the blood test did so in more than 85% of the cases.
