Updated Model Of Alzheimer's Disease Biomarker Sequence Supported And Refined With Clinical Evidence

Brain imaging and biomarker studies presented at AAIC 2013 show an increasingly detailed picture of Alzheimer's progression, starting with amyloid abnormalities and leading to memory and thinking symptoms. BOSTON, July 16, 2013 /PRNewswire-USNewswire/ -- An updated model of the sequence of changes in the brains of people with Alzheimer's disease was reported today at the Alzheimer's Association International Conference® 2013 (AAIC® 2013) in Boston. In the hypothetical model of Alzheimer's progression over time, now refined with several years of clinical evidence, biological markers of changes in beta-amyloid protein become abnormal first, then biomarkers of the degeneration and...
