Simple Blood Test Highly Accurate in Detecting Alzheimer’s Biomarker


A highly accurate blood test detects amyloid, a key biomarker of Alzheimer’s disease (AD), potentially eliminating the need for a lumbar puncture, new research suggests.
The study shows “that plasma Aβ42/Aβ40 accurately identifies individuals with brain amyloidosis, whether they are cognitively normal or cognitively impaired,” study investigator Suzanne Schindler, MD, PhD, assistant professor of neurology, Washington University School of Medicine, St Louis, Missouri, told Medscape Medical News.
These most recent findings, presented here at ANA 2019: 144th Annual Meeting of the American Neurological Association, add to those recently published online in Neurology by the same research group.
