Brain MRI
Currently there are basically two ways to diagnose Alzheimer's disease. One is to obtain cerebrospinal fluid for analysis by lumbar puncture , and the other is MRI. However, both methods have their drawbacks, with lumbar puncture being very painful and MRI being expensive and not available everywhere.
However, according to The Guardian report, scientists now seem to have developed a new method that can determine whether you have Alzheimer's disease through blood analysis. Blood analysis has actually been available before, and it can make a basic diagnosis of Alzheimer's disease through abnormal tau protein, but it is not very reliable. Now a group of scientists from Sweden, Italy, the United Kingdom and the United States are working together to develop a new antibody-based test that can more accurately detect the brain tau protein associated with Alzheimer's disease. After analyzing data from 600 patients, the team confirmed that the new test could reliably distinguish Alzheimer's from other neurodegenerative diseases. Professor Thomas Karikari of the University of Pittsburgh, one of the members of the
research team, said that blood tests are cheaper and safer than all existing technologies, and that new technologies can not only increase the reliability of detection, but also continuously track the progression of the disease. Naturally, the new technology will need to undergo more experiments and expand the target population before it can be gradually promoted. However, it should become much easier to confirm Alzheimer's disease in the future.
