Tests will predict who is developing Alzheimer's and who will benefit most from treatment
By Alice Dembner, Globe Staff *|* July 6, 2004
Years before Alzheimer's ravages memory and robs its victim of the ability to dress or read, scientists believe there are tell-tale signs. Bit by bit, researchers are closing in on a range of tests -- including brain imaging and spinal taps -- designed to reveal those signs and predict who will develop the mind-crippling disease.
''We know that Alzheimer's is probably going on in the brain for decades before people develop symptoms," said Dr. Susan Molchan, an Alzheimer's specialist at the National Institute on Aging. ''Eventually, we hope to be able to tell individual patients . . . what their risk is with greater certainty."
In September, the effort to develop new tests will get a major boost from the start of a five-year, $60 million project overseen by Molchan. The National Institute on Aging will provide about half the funds for the project -- designed to try out tests on hundreds of seniors -- with additional money from drug and diagnostic companies.
Work on treatments is proceeding on a parallel track, and researchers hope that the tests, when perfected, will also help determine who will benefit most from preventive therapies. Currently, there is no cure for the disease and only a few medications that alleviate symptoms.
