WASHINGTON (AP) — In one of the most ambitious attempts yet to thwart Alzheimer’s disease, a major study got underway Monday to see if an experimental drug can protect healthy seniors whose brains harbor silent signs that they’re at risk.
Scientists plan to eventually scan the brains of thousands of older volunteers in the U.S., Canada and Australia to find those with a sticky build-up believed to play a key role in development of Alzheimer’s – the first time so many people without memory problems get the chance to learn the potentially troubling news.
