The microbiota-gut-brain axis is gaining attention as a potential therapeutic avenue for treating illnesses of the illnesses of the central nervous system. In recent years, there has been a notable increase in literature examining the connection between the gut microbiome and its impact on overall health and wellness. The microbiota-gut-brain axis is a promising therapeutic target for treating central nervous system diseases and reducing drug adverse effects. Probiotics have been shown in pre-clinical and clinical trials to improve health by modulating the microbiota in the gut-brain axis. Psychobiotics are probiotics that modulate the gut-brain axis (GBA) and regulate the central nervous system to improve gastrointestinal function, as well as have antidepressant and anxiolytic properties via neuronal, humoral, and metabolic mechanisms. Some psychobiotic strains have been shown to reduce inflammation and cortisol levels, thereby degenerative and neurodevelopmental illnesses such as Parkinson's disease, Alzheimer's disease, and autism spectrum disorder can be effectively treated with psychobiotics. Alleviating anxiety and depression symptoms. Neurodegenerative and neurodevelopmental illnesses such as Parkinson's disease, Alzheimer's disease, and autism spectrum disorder can be effectively treated with psychobiotics. This review summarizes the psychobiotic potential on the gut-brain axis for the mental health.
