A routine blood test may help identify dementia risk many years in advance
Published
A large study examined more than 300,000 adults. The researchers followed the participants over many years to check whether there was a link between the results of routine blood tests and dementia.
The main finding concerns haemoglobin levels. Haemoglobin is a protein found inside red blood cells, and it carries oxygen throughout the body. Its levels are usually checked in a routine blood test. According to the study, abnormal haemoglobin levels may indicate an increased risk of developing dementia, and this can be detected many years before the disease begins.
It is important to understand that the study shows a link between two things, but not necessarily cause and effect. Such a test does not diagnose dementia on its own, so it can only serve as one sign among several. Further research is needed to understand the connection fully.
In summary, the findings suggest that a simple, common blood test may in the future help identify people at risk of dementia earlier. Dementia is a disease that damages memory and thinking ability, so early identification is considered important. However, before the method is used in regular medical practice, it needs to be examined further.
