Gut Microbes: Therapeutic Target for Neuropsychiatric Disorders

Neuropsychiatric diseases encompass a range of mental and neurological disorders that have a significant and far-reaching effect on an individual's quality of life. These conditions affect not only the mental status but also the physical well-being of individuals, which leads to weakened immune systems and other diseases. Emerging research underscores a significant connection between the gut microbiome and neuropsychiatric diseases, suggesting that microbial communities within the gastrointestinal tract may influence brain function and mental health. Gut dysbiosis is caused by various factors, including stress, diet, inappropriate usage of antibiotics, infections, and so on, all of which can disrupt numerous pathways, resulting in abnormal neurotransmitter signaling, inflammation, and impaired brain function. Similarly, various neuropsychiatric diseases can disrupt the specific microbiome in the gut, leading to gut dysbiosis, often impairing memory and cognitive function. The growing evidence supporting the role of gut dysbiosis in neuropsychiatric disorders has opened up new avenues for therapeutic interventions. Modulating the gut microbiome through strategies such as probiotics, prebiotics, or fecal microbiota transplantation has shown promising results in various studies of neuropsychiatric disorders. However, further research is needed to fully elucidate the mechanisms involved in gut dysbiosis-associated brain changes to develop effective and personalized treatment strategies for neuropsychiatric diseases.
