claimThere is mounting evidence that the gut microbiome (GM) and microbial dysbiosis contribute to the common mental health and neurocognitive disorders, including anxiety, bipolar disorder, obsessive‐compulsive disorder, and dementia, via the gut‐brain axis (GBA).

claimIn addition, pro‐inflammatory cytokines decrease the serotonin level, which leads to psychological disorders, such as anxiety and depression, and a consequent decrease in the host immunity.Change in GM as a result of consumption of psychobiotics causes a variety of changes, including nervous, endocrine, and immune responses by affecting a person's cognitive, mood, and behavioral reactivity.

claimA placebo‐controlled trial also showed that depressive symptoms significantly improved in thePS128‐treated patients, with the symbiosis of specific microbial taxa.These studies have shown that the GM plays a key role in regulating brain activity and cognition.

claimOver a billion individuals worldwide suffer from mental and addictive disorders, which account for 7% of the global disease burden, and this burden rises as people age.According to the World Mental Health Report, around 1.095 billion people worldwide, approximately one in seven, are afflicted with mental illnesses, indicating a startling burden of mental health issues.

claimImportantly, this mechanism primarily reflects acute exercise-related serotonergic responses associated with central fatigue and should not be considered mechanistically equivalent to the chronic serotonergic dysfunction observed in major depressive disorder.
