Alzheimer's Blood Tests: Not Ready for Primary Care
MedPage TodayAug 04, 2022
New research from the Institute of Psychiatry, Psychology & Neuroscience at King's College London — published in the journal Brain — has established a blood-based test that can potentially predict the risk of Alzheimer's disease years before clinical diagnosis.
The study found that changes in neurogenesis occurred 3.5 years before a clinical diagnosis, the first evidence in humans that the circulatory system can influence the brain's ability to form new cells, according to the study's authors.
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.
There's a 99% chance that there will be a breakthrough in accurately predicting protein structure before 2031, according to the Metaculus prediction community.
