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. More than 6 million people in the United States and millions more around the world have Alzheimer’s, the most common form of dementia.
