One aspect I’ve found useful is checking out what…

RESEARCH has been done about CIDP or GBS at that doc’s training hospital? For example if they only are focusing on Alzheimer’s? and nothing on Say, MS? [also a demeyelinating issue] then shy them! Further avoid all hospitals [IF you can?] that advocate exclusively the use of steroids for ALL neuro problems. Isn’t so! We all here know that! Web up any interesting doc’s name and see what papers and issues they’ve been participating in… See what the ‘attitude’ is in these papers towards the ‘patients’. IF it seems that they are able to communicate w/patients in their ‘trials’, and if they seem to have open minds about causes etc of neruo issues? Then, they mite be your person! If nothing else? It tells you where/how they ‘formed’ a lot of opinions! Bias in medicine is a big roadblock at times. I hit one at first big-time. I’m not going to do that again.
I don’t know how your system ‘works’. It can take ages to learn such things. I hope you find others who can help you! Best of hopes Truly!
