Scientists Discover “Good” Gut Microbes That Could Protect Against Autism and ADHD

A study found that newborn epigenetic patterns were linked to how infants’ gut microbiomes developed in the first year of life.

Both early epigenetic signals and microbiome changes were associated with behavioral signs of ASD and ADHD by age 3.

Some gut bacteria appeared to have possible protective effects, suggesting a role in lowering later neurodevelopmental risk.

The findings point to early microbial and epigenetic markers as potential tools for prediction and prevention, including diet or probiotic strategies.
