It's great you're exploring the gut-brain connection in autism! Recent studies show a strong link between gut microbiome imbalances and differences in brain activity and behavior in autistic individuals.

A 2023 study even found that children with autism had fewer neuroactive gut metabolites, which correlated with brain differences. Addressing GI issues like constipation can really improve behavior.

For practical steps, consider a diverse, plant-based diet and monitor for any GI symptoms. The Autism Research Institute has webinars on this topic. I hope this helps!
