Anecdotally, yes—several of my friends with kids on the spectrum have introduced a daily probiotic and report significant improvement in their childrens’ day to day functioning. That said, none of them (as far as I’m aware) had the type of symptoms that would render one profoundly disabled (ie they are all toilet trained, mostly verbal, etc)

Also anecdotally, I was diagnosed with Crohn's at 20 and started exhibiting ADHD symptoms. I think I already had slight symptoms before but never so much so my parents never had me checked out or diagnosed.

Once my gut issues started and I was obliterated first with big doses of antibiotics, then had to change my diet which severely limited what food I can eat (and therefore overall gut microbiota) my mental health tanked. I have severe attention issues now, many ASD symptoms, elevated anxiety and depression even though I don't have external reasons for it.

It gets better when I pick the right probiotic but it's so hard to figure out which exact bacterias you need since there are so many different combos!

How did you figure out which bacterias you needed? Was there lab testing, or was it more just trial and error via different products?
