New Alzheimer's blood test predicts who is likely to develop dementia in 5 to 10 years
A new blood test measuring the protein p‑tau217 can predict the risk of developing Alzheimer's disease up to a decade before symptoms appear. The study of nearly 2,700 cognitively healthy adults found that high levels of the biomarker correspond to a 78% chance of cognitive impairment within ten years, while moderate elevations still indicate a 45% risk. Researchers suggest the test could aid early diagnosis and improve recruitment for clinical trials, though experts advise cautious interpretation.
- ▪The test detects p‑tau217, a modified tau protein linked to brain tangles associated with Alzheimer's disease.
- ▪Participants with high p‑tau217 levels had an estimated 78% probability of developing cognitive impairment within ten years and about one‑third within five years.
- ▪Even moderately elevated p‑tau217 levels were associated with a 45% risk of decline over a decade.
- ▪The findings were presented at the Alzheimer's Association International Conference in London and published in the Journal of the American Medical Association.
