The impact of the gut microbiome on long-term health is a hot topic, with tools for assessing microbial composition becoming accurate and affordable. Variations in microbial populations are linked to health, disease, and aging. Researchers are exploring how the gut microbiome affects the brain, particularly astrocyte cells, which play vital roles in neural function. Aging and neurodegenerative diseases can lead to dysfunction in astrocytes, affecting brain health. Understanding the gut microbiota-astrocyte axis is crucial for combating age-related cognitive decline. This review delves into the changes seen in gut microbiomes during aging, astrocyte alterations, and how the gut microbiome influences cognitive function. It provides insights into potential therapeutic approaches for age-related cognitive decline.
