A lot of these problems that these kids have- they have been solved with IVIG, PEX, IV Steroids... If none of that worked, then you move on to more experimental things like the hookworm, looking at gut flora, fecal bacteriotherapy, RTMS- if necessary DBS. My personal opinion is that it's never too late, AND CERTAINLY all of these options should be looked before sending someone away. =( Guess I feel quite strongly about this topic as I have PANDAS and can't imagine how horrible I'd feel if I was sent away as a kid. ESPECIALLY when a couple days of IV steroids brought me completely back. I do hope you find a way out of this. I am sorry for what you are going through. Make sure you look at all of your options carefully! Sometimes things can be so overwhelming that you don't see clearly!
