Imagine your brain is like a bustling city, full of activity and communication. Now imagine that city being disrupted by a rowdy gang of troublemakers. Well, that’s kind of what happens when it comes to the relationship between Alzheimer’s disease and intestinal microflora. In this study, scientists took a deep dive into the gut microbiomes of Alzheimer’s patients and analyzed the levels of inflammatory factors in their blood. They found that the abundance of certain bacteria, like Bacteroides and Proteobacteria, was significantly different in Alzheimer’s patients compared to a normal group. Additionally, they discovered that anti-inflammatory bacteria such as Lactobacillus and Bifidobacterium were less abundant, while pro-inflammatory bacteria like Escherichia were more abundant in Alzheimer’s patients. This shift in bacterial balance may contribute to neuroinflammation, which is known to play a role in the development of Alzheimer’s disease. So, if we can find a way to restore the balance of gut bacteria and reduce inflammation, we might have a promising avenue for preventing or treating Alzheimer’s.

To analyze the structural characteristics of intestinal microflora and changes of serum inflammatory factors of the Alzheimer’s disease, and to explore the relationship between them and dementia, we selected 30 patients in the AD group and 30 patients in the normal group, and collected stool samples to analyze the intestinal flora structure characteristics of the two groups of patients, and statistically analyzed the inflammatory cytokines TNF-α, IL-1β, IL-6, and IL-8 by ELISA from the venous blood of the two groups. The results show that the dominant Bacteroides in the two groups are Bacteroides, Firmicutes, Proteobacteria, and Actinobacteria. The abundance of Bacteroides, Firmicutes, and Proteobacteria in the AD group shows a statistical difference. At the genus level, the abundance of anti-inflammatory bacteria such as Lactobacillus, Bifidobacterium, and Ruminococcus drops in AD group, while the abundance of pro-inflammatory bacteria such as Escherichia and Enterococcus raises. Statistical analysis of inflammatory cytokines in the two groups suggests that TNF-α and IL-6 levels significantly increase in the AD group, with statistical differences. Therefore, it is speculated that the increased abundance of pro-inflammatory bacteria in intestinal flora may lead to or aggravate neuroinflammation through the release of inflammatory factors, thus further leading to the occurrence and development of AD.
