Scientists may be FINALLY closing in on a blood test to to screen people for Alzheimer's disease and replace expensive, impractical brain scans.
So far, Australian researchers have reported that an experimental test did a good job of indicating how much of the telltale Alzheimer's plaque lurks in people's brains by correctly identifying 83% of people at risk and correctly ruling out 85% without the condition.
However, the test will need to be proven successful in larger studies in order to become a means of screening people with memory problems for the disease.
Although a few years away, the senior director of medical and scientific relations for the Alzheimer's Association says the positive results of the test "give us hope that we may be able to use a blood test in the near future."
