The gut microbiome in neurological disorders

Area of Science:

• Neuroscience
• Microbiology
• Genetics

Background:

• The gut microbiome's role in brain function is a growing research area, primarily studied in animal models.
• Emerging evidence suggests the gut microbiome may be a susceptibility factor in neurological disorders such as Alzheimer's disease, autism spectrum disorder, multiple sclerosis, Parkinson's disease, and stroke.
• Altered microbial composition is increasingly linked to the pathophysiology of these neurological conditions.

Purpose of the Study:

• To explore the connection between the gut microbiome and neurological disorders.
• To highlight the need for further human-based research to validate the microbiome's role in disease.
• To investigate the potential of microbiome-targeted therapies for neurological conditions.

Main Methods:

• Review of preclinical and clinical evidence implicating the gut microbiome in neurological disorders.
• Analysis of cross-sectional clinical studies on altered microbial composition.
• Discussion of the influence of diet and exercise on microbiome composition.

Main Results:

• The gut microbiome is increasingly recognized as a potential key factor in neurological disease susceptibility.
• Cross-sectional studies support the link between altered gut microbiota and disease pathophysiology.
• The field requires more robust human data, including longitudinal studies and randomized controlled trials.

Conclusions:

• The gut microbiome's influence on brain function and neurological diseases is a significant area of ongoing research.
• Targeting the gut microbiome may offer novel therapeutic strategies for neurological disorders.
• Systems biology approaches integrating microbiome data with genomic and metabolomic data are crucial for personalized treatment selection.
