According to Yahoo Health, a new study suggests that Alzheimer's-related changes can be detected in the blood years before symptoms manifest. Researchers working with the National Institutes of Health studied 1,350 participants in their 50s and 60s, none of whom had been diagnosed with Alzheimer's disease. They found that certain proteins linked to Alzheimer's were associated with differences in memory and thinking skills.
The study measured proteins like amyloid-beta and tau, which are connected to Alzheimer's disease. Between 4% and 15% of participants showed biomarker levels that could indicate Alzheimer's-related brain changes. Those with higher levels of these biomarkers often performed worse on cognitive tests.
While detecting Alzheimer's early could be beneficial, Yahoo Health notes that blood tests for Alzheimer's are not yet routine screenings for healthy individuals. These tests are primarily used for those already showing symptoms. The study highlights the potential for early intervention, which could be key for newer treatments that slow disease progression.
It's important for older adults to consult with their healthcare providers about new developments like this. Maintaining a healthy lifestyle with regular physical activity, good sleep, and managing chronic conditions remains essential for brain health.
