Opinion: A Baby's Gut Microbiome Could Be Key to Lifelong Brain Health

Experts Holly Baines and George Vradenburg argue that understanding the gut-brain axis from infancy onward is critical for preventing neurological diseases throughout life. The gut microbiome—the community of microorganisms in our digestive system—plays a significant role in brain development and function. Research suggests early microbial colonization may influence cognitive health, mental well-being, and disease susceptibility. The authors call for expanded, rigorous large-scale studies to clarify these connections and their implications for lifelong neurological health and disease prevention strategies.
