Blood Test Seen to Identify Alzheimer’s with Accuracy, Including Early-stage Disease
A new type of analysis allowed researchers to use a blood test to help to identify patients with Alzheimer’s in a group of people with neurodegenerative diseases, a study published in the journal PNAS reports. The test showed far better accuracy than earlier attempts at sampling blood to detect Alzheimer’s. But work is still needed to determine if the test can identify patients who have not yet developed symptoms, the researchers said, and to evaluate its accuracy at differentiating among the disease's various stages of severity.
