Alzheimer’s: blood analysis shows promise for earlier diagnosis

Led by researchers at the University of Central Lancashire (UK), a new study has demonstrated the successful use of blood plasma spectroscopy to diagnose and differentiate various neurodegenerative diseases, including Alzheimer’s disease (AD) and dementia with Lewy bodies. Researchers say that the method allows for rapid, robust and inexpensive diagnosis, as well as segregation between dementias, making it a potentially valuable diagnostic and screening tool. At present, diagnosis of AD lacks a diagnostic tool that is accurate, inexpensive and minimally invasive. In this new study, published in PNAS, researchers report that their method could address these needs by using a...
