ANCHOR LEAD : ANCHOR LEAD: A DIAGNOSTIC TEST FOR ALZHEIMER’S DISEASE MAY BE RIGHT AROUND THE CORNER, ELIZABETH TRACEY REPORTS
In the absence of effective treatment for Alzheimer’s disease, is a recently reported finding of a more successful diagnostic test of any practical significance? Constantine Lyketsos, an Alzheimer’s disease expert at Johns Hopkins, offers his opinion.
LYKETSOS: We’re getting very close to effective diagnosis but I’m not sure what people will be getting out of it. If all we get from these compounds is more accurate diagnosis in symptomatic people who are going to want it and for whom it’s appropriate to use it, I think that’s fine with me, while we wait and see what happens on the therapeutic side. Keep in mind though that these ligands will help us as biomarkers to develop treatments, so even if we might not use them clinically they will help us bring advances in therapy. :28
The test uses PET scanning and a radioactive molecule that binds to amyloid, a material that accumulates in the brain of people with Alzheimer’s disease, and is currently a research tool only. I’m Elizabeth Tracey reporting.
