🟠 Moderate Evidence
A study reported by Science Daily suggests that gut bacteria present at birth may help protect against early signs of autism and attention deficit hyperactivity disorder (ADHD). According to the Science Daily report, researchers found that epigenetic changes present at birth can influence gut microbiome development during a child’s first year, with specific bacterial combinations linked to neurodevelopmental outcomes by age three.
Key takeaways
- Epigenetic changes at birth influence gut microbiome development in the first year of life
- Certain gut bacteria combinations may be linked to autism and ADHD symptoms
- The gut-brain connection begins forming before birth through gene-microbe interactions

Epigenetic Programming Shapes Early Microbiome
According to the Science Daily report, the study reveals that some of the groundwork for brain development may be established before birth through an unexpected partnership between a baby’s genes and gut microbes. The research found that epigenetic changes present at birth can influence how the gut microbiome develops during the first year of life.

Bacterial Combinations Linked to Neurodevelopment
The Science Daily report indicates that researchers identified associations between specific combinations of gut bacteria and early signs of autism spectrum disorder and ADHD. According to the study, certain combinations were linked to early signs of autism and ADHD by age three.
The World Health Organization estimates that autism affects 1 in 100 children worldwide, making these research findings potentially significant for understanding neurodevelopment.
Research Implications
This research provides insights into how early factors might influence neurodevelopmental outcomes. The study suggests that the gut-brain connection may be established earlier than previously understood, according to the Science Daily report.

Future Research Directions
While these findings provide evidence for associations between early gut bacteria and neurodevelopment, questions remain about the mechanisms involved. The Science Daily report describes this as a major study examining the relationship between epigenetic changes, gut microbiome development, and neurodevelopmental outcomes.
Researchers found that epigenetic changes present at birth can influence how the gut microbiome develops during the first year of life, and certain combinations were linked to early signs of autism and ADHD by age three.
