Despite extensive research and encouraging findings, Alzheimer鈥檚 disease (AD) remains difficult to diagnose based on signs and symptoms alone. But what if one day, a blood sample during an annual check-up could be used to identify the disease? A has found that a new kind of blood test is as effective at detecting AD as lumbar punctures, one of the current methods used to diagnose AD. Lumbar punctures, which are conducted by inserting a needle into the lower back to extract cerebrospinal fluid (CSF), are invasive and may not be accessible to all patients. Building on previous work in which they developed the new blood test for AD in collaboration with scientists at the University of Gothenburg, the researchers studied a cohort of 174 individuals evaluated by dementia specialists. They assessed whether the same components that are commonly used to detect AD in CFS could also be used to detect AD in blood plasma. The results indicate that one of the components, p-tau217, was equally as effective as a biomarker for detecting AD in both blood plasma and CSF. The researchers say this may reduce the need for invasive lumbar punctures without compromising accuracy in the identification of AD. 鈥淭hese results suggest that the superior scalability and availability of blood biomarkers for Alzheimer鈥檚 disease are not offset by worse accuracy, paving their way to one day be used in clinical practice,鈥� says Joseph Therriault, PhD candidate in the Department of Neurology and Neurosurgery under the supervision of Dr. Pedro Rosa-Neto and lead author of the study.
