Story summary
- Researchers at the Scripps Research Institute developed a blood test to detect Alzheimer's earlier by analyzing the shape of specific proteins, not their quantity.
- The study, published in Nature Aging, analyzed plasma from 520 individuals and identified three markers—C1QA, Clusterin, Apolipoprotein B—that distinguished healthy, mild cognitive impairment, and Alzheimer's cases with up to 93% accuracy.
- The approach could improve early diagnosis and treatment, but requires further validation before clinical use.
