The Brain-Gut-Microbiome Axis in Psychiatry

Area of Science:

• Neuroscience
• Gastroenterology
• Microbiology

Background:

• The brain-gut axis describes the bidirectional communication between the brain and the gastrointestinal tract.
• This interaction is increasingly understood to involve the gut microbiome, with significant clinical implications.
• Recent advancements in microbiome analysis have spurred numerous preclinical and clinical investigations.

Purpose of the Study:

• To review the clinical applicability of the brain-gut-microbiome axis.
• To discuss potential therapeutic directions for improving psychological symptoms by targeting this axis.

Main Methods:

• Literature review of preclinical and clinical studies.
• Analysis of research on the interplay between the brain, gut, and microbiome.
• Examination of the role of the hypothalamus-pituitary-adrenal axis in mediating these interactions.

Main Results:

• Psychotic symptoms can alter the intestinal microbiome composition.
• The gut microbiome influences psychological factors through microbial metabolites and neurotransmitter synthesis.
• The brain-gut-microbiome axis presents a novel therapeutic target for mental health conditions.

Conclusions:

• The brain-gut-microbiome axis is a critical area for understanding and treating psychological disorders.
• Further research into this axis could lead to innovative clinical applications for mental well-being.
• Targeting the gut microbiome offers promising avenues for managing and improving psychological symptoms.
