Georgetown University researchers are reporting a new blood test that predicts the onset of Alzheimer’s disease with 90% accuracy. If the blood test is positive, researchers indicate that the person will likely develop Alzheimer’s in the next three years.
The first stage of Alzheimer’s is mild cognitive impairment and the reduced brain activity can be seen in a scan. With the new blood test, the breakdown of nerve cell membranes can be detected far in advance of a scan.
An individual diagnosed with Alzheimer’s normally has a post-diagnosis life expectancy of seven years. While the new blood test offers no new hope in treating the disease, researchers believe that the new three-year window will provide more insight into the disease and allow a lot of extra time to study the formation of the disease in greater detail.
A new question being raised is how effective a treatment might be when applying it far earlier in the life cycle of Alzheimer’s?
Researchers also point out that delivering the earlier news of Alzheimer’s is not something everyone is in favor of – and that includes both doctors and patients.
