- Researchers developed a blood test to detect Alzheimer's progression by measuring tau fragments (eMTBR-tau243) in blood.
- The test helps identify suitable drugs like donanemab and lecanemab for early-stage Alzheimer’s patients.
- Elevated eMTBR-tau243 levels correlate with cognitive impairment and dementia but not other conditions.
- The test is scientifically promising but requires further validation and simpler detection methods for routine use.
- Another study found the ratio of proteins YWHAG:NPTX2 in brain fluid predicts cognitive decline better than amyloid beta or tau levels.
- These findings could improve drug selection and clinical trial design for Alzheimer’s patients.
