Rules seek to expand diagnosis of Alzheimer’s

The New York Times, July 14, 2010

For the first time in 25 years, medical experts are proposing a major change in the criteria for Alzheimer’s disease, part of a new movement to diagnose and, eventually, treat the disease earlier.The new diagnostic guidelines, presented Tuesday at an international Alzheimer’s meeting in Hawaii, would mean that new technology like brain scans would be used to detect the disease even before there are evident memory problems or other symptoms. If the guidelines are adopted in the fall, as expected, some experts predict a two- to threefold increase in the number of people with Alzheimer’s disease. Many more people would be told they probably are on their way to getting it. The Alzheimer’s Association says 5.3 million Americans now have the disease.
