Anchor lead: A new study may point the way to early detection of Alzheimer’s disease, Elizabeth Tracey reports

Finding out that people are on the road to developing Alzheimer’s disease early may make intervening more effective, and a new test developed at Johns Hopkins may suggest a way. Laurent Younes, chair of the department of applied mathematics and statistics, describes the study.

Younes: What we developed is a statistical model to try to detect a possible change point in several markers that are related with Alzheimer’s disease, this change point occurring several years before the disease itself is manifest.  :17

Younes says a very long term study called Biocard provided the data.

Younes: This is made possible by the existence of the Biocard study that enrolled patients 20 or more years ago when they were cognitively healthy so data was acquired before the onset of the disease.  :16
