Summary
A new finger-prick test may help diagnose Alzheimer's disease more easily. Researchers found that a simple blood sample from the fingertip could detect Alzheimer's-related proteins with about 86% accuracy, similar to more complex tests. This method could make testing easier and more accessible, but it needs more research before it is commonly used.
Key Facts
- Alzheimer's disease affects roughly 7.2 million Americans aged 65 and older.
- Current Alzheimer's tests involve expensive brain scans or spinal fluid tests.
- Researchers tested a method using blood samples from the fingertip on 337 people.
- The test measures proteins associated with Alzheimer's, including p-tau217.
- The accuracy of the finger-prick test was about 86%, similar to current tests.
- Participants could gather their samples without medical staff, useful in remote areas.
- The test is not yet ready for clinical use and requires further study.
- Early detection of Alzheimer's can lead to better life quality and treatment options.
