It's thrilling that we are able to witness this revolution in Alzheimer's disease diagnosis, as some one-quarter of clinical diagnoses are wrong, but blood-based biomarkers are not ready for widespread use yet. For them to be used as stand-alone tests in primary care, additional research is needed.
Though still costly and limited, blood tests for Alzheimer's disease are already a reality that can help to diagnose this devastating illness. Equally important, the development of these tests — which go hand-in-hand with finding a treatment — advance research and bring awareness. More data and research is always needed, but the future is bright, and hopefully, tests will soon be widely adopted.
