But how well do current blood tests work for that purpose?
At the Alzheimer's Association International Conference in London on July 12-15, Live Science spoke with researchers and clinicians who study and use blood tests for Alzheimer's disease. Here's their take on the current state of these tests and their practicality for real-world use

That's because the first "disease-modifying" drugs for Alzheimer's, which target the disease's causes rather than its symptoms, have been approved in recent years.
