Summary

This study looks at how the gut microbiome (the bacteria in our intestines) is linked to stress in children with autism or those who have experienced trauma. Researchers will give 75 children, ages 4 to 7, a probiotic powder for 4 weeks and measure changes in their gut bacteria and stress hormone levels. The goal is to better understand the connection between the gut and brain, not to test a treatment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Probiotic (dietary supplement)
What this could lead to
If successful, this could help us understand whether changing gut bacteria might help children with autism or stress manage their reactions better.
What could go wrong
This is a small, early-stage study with no control group for the probiotic. Results may not apply to all children, and the probiotic may cause mild digestive upset.
