Interesting thread, I have been wondering the same thing. Mz. Migraine, thanks, I was 52 (will be 55 shortly) when awarded and have looked through my paperwork time and time again. There are no dates or timetable on my own paperwork; no mention of a review at all. However, in the conclusion or rather summary it does say "permanently disabled". Does this make a difference? I would think it does but I just don't for certain either.
