Research Progress on Gut Microorganisms Affecting Mental Illness and Cognitive Function

Abstract

Gut microorganisms affect host's depression, anxiety and other mental diseases. Recent studies have shown that there is a certain correlation between gut microorganisms and diseases of the central nervous system. On the one hand, gut microorganisms can affect the development and function of the brain through the gut brain axis. On the other hand, the brain also changes the structure and composition of gut microbes through the gut brain axis. This paper reviews the interaction between gut microorganisms and brain through the gut brain axis, focusing on the study of gut microorganisms and brain function, psychology, cognition and other fields. It provides a new idea for the research of related mental diseases and cognitive dysfunction.
