Neuropsychiatric perspectives on the microbiome: Unraveling the complex interactions between chemical substances, probiotics, and mental health

In the field of neuropsychiatry, researchers are increasingly focusing on the influence of the gut microbiome on mental health. This perspective explores the interactions between probiotics, chemicals, and the gut microbiome. Recent studies suggest that gut dysbiosis (GD) may have a direct impact on brain function, influencing cognition and the development of neuropsychiatric disorders. There are also numerous factors that can influence GD, including environmental factors, such as diet. Individuals with neuropsychiatric disorders show differences in the gut microbial community compared to healthy individuals. Pharmaceuticals interact with the gut microbiome, modulating its effects on mental health. However, probiotics offer potential as complementary therapy, restoring microbial balance and influencing neurotransmitters such as serotonin and gamma-aminobutyric acid (GABA). This review explores the complex interactions between the gut microbiome, psychopharmaceuticals, and probiotics, aiming to identify novel research directions and therapeutic strategies to improve mental health treatments. The purpose of this review is to analyze the literature on how these interdisciplinary relationships contribute to the understanding of neuropsychiatric conditions in order to promote new research directions aimed at modulating these aspects to improve current treatments.
