ALZHEIMER'S BLOOD TESTS OFFER NEW PROMISE TO DIAGNOSE AND PREDICT THE DISEASE

Summary from the TLDR newsletter

Blood tests for Alzheimer's disease could eventually transform the way the disease is diagnosed and even predict who might develop it and when. There are still questions about their accuracy, so they shouldn't be used diagnostically for people who don't have cognitive impairment. However, they appear to be effective for predicting risk when paired with other factors. There are currently no treatment options available for people without symptoms, but that could change in the next couple of years as some therapies are currently in clinical trials.
