A simple blood test could make early Alzheimer’s detection faster and cheaper, researchers say
New blood test could revolutionize how Alzheimer’s disease is detected
- Researchers at U.C. San Diego have developed a new blood test for Alzheimer's disease, aiming for faster, cheaper, and less invasive early detection.
- The test identifies increases in specific blood proteins linked to brain inflammation and nerve cell damage, which are associated with cognitive decline.
- Current diagnostic methods for Alzheimer's include expensive brain scans or the Lumipulse blood test, which costs between 500−500−1,200 and is not covered by insurance.
- While promising, researchers advise that the new blood test should complement existing diagnostic approaches rather than replace them, as its large-scale utility is still being evaluated.
- Early detection is vital for patients and their families to plan, as treatments are most effective in the early to middle stages of the disease, with the study focusing on Hispanic adults who face a higher risk.
