Gut-Brain Axis and Neurological Disorders-How Microbiomes Affect our Mental Health.

Area of Science:

• Neuroscience
• Microbiology
• Gastroenterology

Background:

• The gut microbiota plays a crucial role in maintaining gastrointestinal health.
• Emerging evidence highlights the gut microbiota's influence on brain function, behavior, and mood.
• The gut-brain axis, a bidirectional communication pathway, is implicated in neurological disorders.

Approach:

• This review synthesizes preclinical and clinical studies on the gut-brain axis.
• It examines the role of gut microbes in producing and modulating neurotransmitters.
• The review discusses research involving germ-free mice, fecal microbiota transplantation, and animal models.

Key Points:

• Gut microbes produce neurotransmitters like GABA, serotonin, and dopamine.
• Microbial metabolites can regulate neurological and immunological activities in the brain.
• The gut microbiota is linked to the pathogenesis of neurological conditions such as schizophrenia, depression, and anxiety.

Conclusions:

• The gut-brain axis represents a significant area for understanding neurological disorders.
• Probiotics and prebiotics show potential in modulating neurological conditions.
• Further research is needed to develop novel therapeutic strategies targeting the gut-brain axis.
