Probiotics in Traumatic Brain Injury: New Insights into Mechanisms and Future Perspectives

Area of Science:

• Neuroscience
• Gastroenterology
• Microbiology

Background:

• Traumatic brain injury (TBI) is a global health concern with multi-organ effects, including the gastrointestinal (GI) tract.
• The gut-brain axis describes the bidirectional communication between the GI tract and central nervous system.
• TBI is associated with intestinal barrier dysfunction, inflammation, and gut dysbiosis.

Purpose of the Study:

• To review current evidence on the benefits of probiotic administration in patients with TBI-related complications.
• To identify potential novel therapeutic strategies using probiotics for TBI management.

Main Methods:

• Review of preclinical and clinical studies.
• Analysis of research on probiotics' effects on inflammation and gut microbiota in TBI patients.

Main Results:

• Probiotics can modulate inflammatory processes and alter gut microbiota composition.
• Animal studies and human trials show probiotics reduce inflammation, infection rates, and intensive care duration in brain-injured patients.

Conclusions:

• Probiotics demonstrate potential as an effective adjuvant therapy for TBI complications.
• Further research can leverage probiotic benefits for novel therapeutic strategies, given their safety profile.
