The goal of the Alzheimer's Disease Neuroimaging Initiative

This is Science Today. The Alzheimer's Disease Neuroimaging Initiative, or ADNI, is a 60-center study funded by the National Institute on Aging. The ultimate goal is to find a biomarker for Alzheimer's that would predict who will later develop the debilitating neurodegenerative disorder. Susan Landau, a research scientist at the University of California, Berkeley, led a study that found such early markers.

Landau:          Specifically, people who had poor memory recall performance and low glucose metabolism in particular areas of the brain called the parietal and temporal lobes were more like to convert to Alzheimer's disease - actually fifteen times more likely than people who were normal on those measures.

Narrator:        Landau says ADNI's goal is to develop and perfect methodology.

Landau:          It's a big part of this study is to try to get everyone on board with what the best ways are of analyzing the data to make it useable for clinical trials and for doing research on a larger scale than is just one laboratory at one university.

Narrator:        For Science Today, I'm Larissa Branin.
