As we get older our health issues become more complex and treatment more difficult. Are you near a teaching hospital where your mix can be evaluated, more so than unconnected doctors? Have you seen an ophthalmologist regarding the vision changes; dry eye, pressure, or macular issues can be treated and those should be addressed to avoid damage. If dry eye is a factor, then preservative-free eye drops help and gel drops before bed (been there, done that). My moderate TBI was 32 years ago and I still have word-finding problems, but now have a normal EEG, so doctors don't always see the fine print. It would be good to keep a journal of all your symptoms, including taking BP measurements. I hope your endocrinologist visit bears fruit and that you are able to get answers to your health problems, but it is a frustratingly slow process.
