A simple blood test could reveal Alzheimer’s risk 10 years before symptoms

AI Summary

An international study suggests a blood test could predict Alzheimer’s-related cognitive decline up to a decade before symptoms appear. Researchers estimated that people at highest risk have a 38% chance of impairment within five years and a 78% chance within ten years, potentially enabling earlier intervention.

A major international study found that a simple blood test could help predict Alzheimer’s-related cognitive decline years before symptoms appear, with the highest-risk individuals facing a 38% chance of impairment within five years and an estimated 78% chance within 10 years. Scientists believe the discovery could pave the way for earlier intervention and future treatments designed to prevent Alzheimer’s before memory problems begin.
