Efficacy of a blood test that can predict the onset of Alzheimer's disease was verified
A team of researchers identified a protein in the blood whose behavior functions as an early indicator of Alzheimer's disease.
TL;DR
- A new blood test can identify early Alzheimer's disease risk by detecting the p-tau217 protein.
- The test may predict dementia risk in women up to 25 years before cognitive decline is apparent.
- Elevated p-tau217 levels are linked to the formation of tangled filaments in the brain, characteristic of Alzheimer's.
- The study analyzed data from 2,766 women in the Women's Health Initiative (WHI) study.
- Predictive accuracy of the biomarker can vary based on genetic factors (APOE e4 allele), age, and hormone therapy use.
- This early detection could lead to personalized prevention strategies and delayed disease progression.
