This is helpful. There is definitely a brain-gut connection. Having been a Biology major in college, with an interest in the evolution of species, I can say I understand why there is a brain-gut connection in the evolutionary record: at one time the gut and (precursor to) the evolving brain were linked and part of one central tube. (Current science professionals welcomed to pitch in here!)

But I did want to ask how and where (&/or what kind of doctor, what kind of medical system) did you find that could actually test you? Recently trying - once again - to find legitimate, trustworthy and professional source/s for neurological testing, and have only been referred (unknowingly, apparently, by my therapist/LCSW and new PCP's nurse) to very unreliable and unprofessional places - businesses, really - that want a credit card up front, are - when you look into it further - NOT affiliated with the Better Business Bureau, have multiple seriously bad reviews about overcharging, not providing services, and pretty much being some kind of "mill-like" operation for processing people, and NOT really interested in a personal, confidential, professional approach to a serious, highly private subject.

If I can see about somehow visiting with a professional, a neurologist it seems, in an established reputable medical system, without opening a can of worms into "over-diagnosing" issues, then maybe I can at least set a baseline for ongoing care.

It's dehumanizing to talk with a telemarketer/nonprofessional about what kind of testing you want, and they end up saying you need to provide a credit card, Oh! come in first for a complete medical evaluation, and on and on.

Appreciate any help and direction you can provide from your experience.

Mayo Clinic Connect has been the most helpful partner on this journey that I have ever found. Worth a lot especially these days!
