Rather extraordinary claims were recently made by researchers in a Nature Medicine article that may forever change the long-term care planning landscape.
Scientists from Georgetown University are claiming to have developed a blood test that can determine whether an individual will develop dementia symptoms within two or three years. Their findings suggest the test is 90% accurate. While few are questioning the researchers methods, it is still to early to know if the results will hold up in future studies. This initial group consisted of only 525 total participants (all over age 70), with only 28 of that group ultimately developing symptoms. More efforts are already underway to test larger groups and potentially verify the results.
While this test offers nothing in the way of a direct cure to prevent Alzheimer’s or minimize symptoms, it still may eventually lead to treatments. That is because some research argues that all previously attempted therapies failed because they were only begun after someone showed the symptoms–at which point it may have been too late. However, if this test proves accurate, then treatments can begin earlier that may actually be effective.
