- Field
- medicine and diagnostics
- What they did
- Researchers conducted a clinical trial where older adults with early signs of cognitive impairment took multistrain probiotic supplements for about six months. Participants taking probiotics showed better results on cognitive tests compared to the placebo group and experienced a significant reduction in pTau181 levels in their blood.
- Why it matters
- pTau181 is a blood-based biomarker for Alzheimer's disease, as elevated levels in the blood often precede dementia symptoms and reflect changes occurring in the brain.
