A brand new blood test that seems to be able to properly identify Alzheimer’s disease might be as accurate as a full-on and, of course, incredibly expensive brain scan or even a spinal tap when it comes to discovering the condition. This essentially raises the possibility of a new, incredibly cheap option to diagnose Alzheimer’s, which is in fact the most common form of dementia that there is, at least to the current knowledge of the medical community.
Scientists affiliated with the Alzheimer’s Association International Conference, that just took place on Tuesday, have presented the results of a number of their studies regarding whether a simple test of blood could or could not distinguish between Alzheimer’s disease and, potentially, other forms of dementia as well.
A particular study was published in the well-known academic journal called JAMA and, according to scientists, one blood test could identify Alzheimer’s disease and even detect signs of another disease about 20 years before the first symptoms would appear in a group of people that have the unfortunate genetic mutation that causes Alzheimer’s.
A blood test capable of detecting the dreaded Alzheimer’s disease could be a lot more precise than the thinking and the memory tests that are currently used to detect the condition. The procedures of brain scans and spinal taps are invasive and, most of all, expensive, so insurance often does not cover the costs of looking into these possibilities.
Scientists have declared the fact that a blood test looking into the tau protein could distinguish Alzheimer’s from other forms of dementia that exist with an accuracy that ranges between 89% and 99%. According to Dr. Eric Reiman, who is an expert on the matter, this opportunity seems to be a promising blood test that could change testing for Alzheimer’s all over the globe.
