Hello, Dahlek: Thanks for your information and comment. I am resigned now to never having a clearcut diagnosis; rather, I will be sent from doctor to doctor and take test after test, with nothing conclusive being shown at the end. In the meantime, my condition will go from bad to worse. Fate may surprise me, but, again, I doubt it. There seem to be too many things that are not well understood about neuro diseases at present; someday, they will be, but not in my time. So that is what, in your terms, my brain and gumption are telling me. My intuition, which may be wrong, is in play; after all is said and done, all the information and facts and conversations and tests are over, intuition is what remains. I'd like to be optimistic. There is a certain point, however, at which even hope -- the only item that did not escape Pandora's box -- escapes, flies away, never to be seen again.
