Abstract
Sixteen gut bacterial taxa are associated with a reduced risk of Alzheimer's disease, while twelve taxa are linked to an increased risk.
- A two-sample Mendelian randomization analysis was conducted to explore the relationship between gut microbiota and Alzheimer's disease.
- Certain gut bacteria from the phylum Tenericutes and classes Bacilli and Clostridia are linked to a lower risk of Alzheimer's disease.
- The presence of 12 specific gut bacterial taxa, including those from class Actinobacteria and Betaproteobacteria, is correlated with a higher risk of Alzheimer's disease.
- Observations indicate that these gut bacteria may have a causal influence on Alzheimer's disease risk.
