i have heard about the microbes in your gut and how those could lead to AD and maybe even autism. my son has problems with executive functioning, working memory and memory retrieval. is there a way to check his gut microbes? we eat a very well balanced diet. i have tried excluding dairy and gluten (at separate times), however these do not seem to have an effect. do you know ways to correct these gut microbes with diet, if so what suggestions do you have.
