I’d like to comment on this thread I read here today. I am not as impacted as what you’ve shared , but I’ll put in my two cents from where I’m at. I’m a trained OT(Occupational Therapist) , not that that matters , but I’ve taken neurology courses as part of that and loved learning that information. Anyway, I am Type A, and after going to school and learning of the parasympathetic PNS -rest and relax , and sympathetic SNS -fight or flight-parts of the Autonomic Nervous System ANS , I always felt that I was definitely geared more toward the SNS . Anyway . fast foward many years into the future. Started having problems with balance at times mostly when getting out of a car after traveling , getting up off a couch after watching TV . Reading became an issue when I stopped and looked away from the written text, same with using computers or IPhones. Along with that came my head feeling foggy, like I wasn’t really in the situation , but was. It took years of a variety of appts and finally a Vestibular Training PT hit on something that helped . She labeled (all that previous discussion ) Vestibular Migraine. I went to therapy and did a variety of exercises/activities that included balancing while visually looking at a target , or moving your head up and down , or side to side while looking at targets, etc and other things. But suffice it to say it was a thought out , progressive , sequential program based on your ability to handle the incoming information. (I’ll just say there were parts of your description that sounded a bit like that) Please be aware if anyone is thinking any PT can do this treatment…. In my experience YOUR WRONG. I saw a few PTs before landing with this one and they gave me handouts , had been to a conference and thought they had all they needed to help me, or simply were trying to help me with what knowledge they had . Which wasn’t enough or complete. Any people out there having those issues look up on you tube Dr. Shen Beh , and Talk To Me Dizzy , 2 PTs that are experienced in this area. Now going on in my life , last year I fracture a lumbar vertebrae due to osteoporosis and that lead me to much self learning . I have learned a lot about diet , gut health and all that as part of that and then tripped over Dr. Peter Kan, an Integrative Functional Dr -and I recently took his Vestibular Master Class, because of my nagging knowledge of my vagus nerve and it’s direct impact on the SNS and PNS. Enlightening!!! Lots to digest but was up for the task of 5 days learning. Vagal tone in one’s body is a real thing and though , obviously we need both systems , they need to work effectively and in a balanced manner to function our best. Yes, all the basic bodily functions from the brain on down , the vagus nerve has a branch going to all major organs. Which I did know, but he taught in a very understandable way how all the feedback loops and interconnections are made. And how there are building blocks of functioning that are essential to have things working well. So enlightening and thrilling to get this information.I’ll just say …. Oxygen delivery , Blood sugars. and Digestive/gut health are the foundational blocks upon which all other things build off of , and there are loops up and down from them to the brain. This doesn’t just relate to physical well being , but ALSO mental health well being .With many other things in between. But I’ll stop there. I highly recommend at least a peak at some of that info. Good luck to you and all who might have read this and found something in here that’s useful to you!
