Psychobiotics are probiotics microrganisms that affect the central nervous system neurological functions of a host. The gut-brain-axis via immune-metabolic pathways balances the gastrointestinal function and improves the quality of life of hosts with psychiatric disorders. Gut microorganisms have been found to participate in the balance of various psychiatric disorders, including "Anxiety and Depression", "Alzheimer’s disease", "Parkinson's disease", "Autism Spectrum Disorder" and "Tourette syndrome". Scientific evidence points to an association between gut microbial imbalance and psychiatric disorders. The microbiome-gut-brain axis is a target for treating psychiatric disorders using nutritional strategies, such as through the intake of probiotics. Here, we report the main effects of psychobiotic therapy against psychiatric disorders. In conclusion, psychobiotics showed considerable neurological benefits, which opens avenues for new scientific research in vivo towards treating psychiatric disorders.
Key words: Probiotic food, microbiome-gut-brain axis, mental health.
