U.S. health officials on Friday endorsed the first blood test that can help diagnose Alzheimer’s and identify patients who may benefit from drugs that can modestly slow the memory-destroying disease.
The test can aid doctors in determining whether a patient’s memory problems are due to Alzheimer’s or a number of other medical conditions that can cause cognitive difficulties. The Food and Drug Administration cleared it for patients 55 and older who are showing early signs of the disease.
