A new video technique allows scientists to track progression of Alzheimer's
disease through the brains of living patients, researchers report today in
The Journal of Neuroscience.
The technique involves a computer-generated 3D video derived from single brain scans taken over time, reports The New York Times. It could help doctors and pharmaceutical companies track the progression of new anti-Alzheimer's drugs, experts say.
The technique was devised by scientists representing the University of
California at Los Angeles, the University of Queensland in Australia, Addenbrooke's
Hospital in England, and GlaxoSmithKline Pharmaceuticals.
After using the technique on 12 Alzheimer's patients, the researchers
found that brain loss progressed at up to 5 percent a year in people with
the disease, versus about 0.5 percent annually among people who aged normally.
