Many people believe that being diagnosed with cognitive degenerative diseases like Alzheimer's is just about forgetting things. However, it is not that simple. The Alzheimer's diagnosis comes with not just lost memories, but also changes in the way you think, the way you behave as well as losing the memories and important factors of your life. One of the most devastating facts about these cognitive diseases is the difficulty in diagnosing them early. There has been a lot of research done on how to identify early signs and symptoms of diseases like Alzheimer's; however, their accuracy is still under scrutiny. A recent research showed that a simple blood test can accurately spot early signs of Alzheimer's disease. Experts have found that these blood tests can reliably find dementia by looking at two specific proteins in the blood. New Blood Test for Alzheimer's Scientists are excited about a new blood test that can really well find early signs of Alzheimer's disease. This test looks for two proteins, amyloid beta 42/40 and p-tau217. These proteins are linked to sticky clumps that build up in the brains of people with Alzheimer's. The test is very good at finding people with memory problems, with a 95% success rate. This means it hardly ever missed a case. It also correctly said that people did not have dementia 82% of the time. This amazing new test has even been approved by the Food and Drug Administration (FDA) in the US. Why This Test Is Important The number of people getting dementia is expected to go up a lot. Because of this, it's really important to find out if someone has it quickly and correctly. Scientists say this new blood test works just as well as the harder and more uncomfortable tests used now. It's also much easier and cheaper. Levels of the p-tau217 protein were much higher in people with Alzheimer's. Next, they will test it on even more people, including those who might have early Alzheimer's but don't show any memory problems yet. Experts think this blood test will make finding Alzheimer's much faster, easier, and available to more people. While it mainly helps with Alzheimer's, the test was also used on people with other types of dementia. This suggests it could help figure out what's causing memory problems. Pushing for Blood Tests in the NHS There's a big project called the Blood Biomarker Challenge. It's supported by large charities and aims to bring blood tests for dementia diagnosis to the NHS by 2029. These tests are seen as super important for making diagnoses quicker. This will give more people faster access to the care, support, and treatments they really need. Investing in these new tests and the staff to use them is key, especially as new treatments for dementia are coming soon. What's Next for Diagnosis This new study adds to more and more proof that blood tests can find the diseases that cause dementia, even in people with early memory issues. But, we still need more research to see how well these blood tests work for everyone in everyday life. This is because people in studies might not always be exactly like all the people affected by dementia. Projects like the Blood Biomarker Challenge in the UK are working to gather this proof. This work will be a big step in making diagnosis easier and faster, helping us get closer to finding a cure.
