By the way, WORLD-CLASS neurologists at the University of Chicago! We've seen four other neurologists here in Des Moines, Omaha and Iowa City. They all simply read what the first doctor wrote in his chart and they all just went along with what the first guy wrote--that there was nothing wrong with my husband. Institutional Bias sucks! It took us a year to see someone who didn't care what any previous doctor said and they had him diagnosed in three hours. Sigh. We hate the diagnosis, but we've known for a while he had at least PLS....at least we were validated and not shooed out another door, again.
