Researchers Test Healthy Seniors In Big To Block Alzheimer’s

WASHINGTON (June 9, 2014) Scientists are launching a major study to determine if an experimental drug can protect healthy seniors whose brains harbor silent signs that they're at risk of Alzheimer's disease.

The effort is one of the most ambitious attempts yet to thwart Alzheimer's.

Researchers expect to screen thousands of volunteers ages 65 to 85, hunting for those whose brain scans show they have a sticky build-up believed to play a key role in development of Alzheimer's.

The marker doesn't guarantee someone will develop Alzheimer’s, but the study will test if early use of a drug designed to target the gunk makes a difference for those who do.

Whether the drug works or not, researchers say the unique study should give new insight into Alzheimer's risks and how people cope with the knowledge.
