Connecting the Dots: The Interplay Between Stroke and the Gut-Brain Axis

Area of Science:

• Neuroscience
• Gastroenterology
• Microbiology

Background:

• The gut-brain axis involves bidirectional communication between the central nervous system and the gastrointestinal tract.
• Gut dysbiosis, enteric nervous system (ENS) alterations, and vagus nerve dysfunction are implicated in stroke development.
• Inflammation and oxidative stress are key factors in stroke, potentially influenced by the gut microbiome.

Purpose of the Study:

• To review the current understanding of the gut-brain axis's role in stroke.
• To explore the potential of targeting the gut-brain axis as a therapeutic strategy for stroke.

Main Methods:

• Literature review of animal and human studies on the gut-brain axis and stroke.
• Analysis of research on gut microbiota composition and its impact on stroke outcomes.
• Examination of therapeutic interventions targeting the gut-brain axis.

Main Results:

• Animal studies show that modulating gut microbiota can improve neurological function and reduce stroke infarct size.
• Human stroke patients exhibit altered gut microbiota composition.
• Evidence suggests a link between gut dysbiosis and increased inflammation/oxidative stress in stroke.

Conclusions:

• The gut-brain axis is a significant factor in stroke pathophysiology.
• Targeting gut dysbiosis and the gut-brain axis presents a promising therapeutic strategy for stroke.
• Further research is warranted to develop effective gut-brain axis-based interventions for stroke.
