How the gut microbiome affects brain development in preterm infants
Official title: The Gut Microbiome Brain Axis and Preterm Infants
Funded at University of Chicago · NIH-11010353 · Data updated 2026-11-12
This study is looking at how the bacteria in the guts of preterm babies might affect their brain development, hoping to find ways to support their growth and health as they grow up.

Who could benefit from this research
✓Could help
Ideal candidates for this research are preterm infants who are currently receiving care in a neonatal intensive care unit (NICU).
✕Less likely to help
Patients who are not preterm or those who are beyond the neonatal stage may not benefit from this research.
What this research studies
This research investigates the relationship between the gut microbiome and brain development in preterm infants, a vulnerable group at risk for long-term neurodevelopmental issues. By analyzing fecal and blood samples from preterm infants in the NICU, the study aims to identify specific gut microbiome taxa and metabolites that may influence neurodevelopmental outcomes. The research will track changes over time to understand how early microbiome composition can affect brain health as these infants grow. This approach combines advanced genetic sequencing techniques with clinical observations to uncover potential interventions.
Why it matters
Potential benefit: If successful, this research could lead to new strategies for improving neurodevelopmental outcomes in preterm infants.
How similar studies have gone: Previous research has shown promising results in understanding the gut-brain axis, suggesting that modifying the gut microbiome could positively impact neurodevelopment.
