Case ReportHuman
The study gave fecal transplants to people with memory problems and found they scored better on memory tests afterward, which supports the idea that this treatment can help Alzheimer's symptoms like memory and thinking.
Case ReportHuman2024
This study found that Alzheimer's patients who got fecal transplants from healthy donors had better memory and thinking scores after three months, supporting the idea that FMT can help with some symptoms, but it didn't test mood changes.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
