The Link Between Gut Microbiota and Alzheimer's Disease.
Researchers from the University of Nevada, Las Vegas, have identified a correlation between Alzheimer's disease and specific gut microbiota populations. They found that 20 out of 119 genera were significantly associated with Alzheimer's disease diagnosis, with six identified as likely risk species and the other 14 potentially protective species. The most significant risk-associated species was Bacteroides, while the most significant protective genus was Intestinibacter. The study also found that Collinsella from the phylum Actinobacteria was identified as a risk factor for Alzheimer's in both the discovery and replication samples and had the most significant associations with the APOE genotype at rs429358-C.
