Hi, yes, my mother has had 2 scans, one 2.5 years ago that found there were 2 small black spots on her brain (causing the memory problems) and then last year we asked for her to have another one as she has deteriorated so quicky and they said there was no significant change from the previous one which I find SO hard to believe. But we have to trust the doctors, don't we? My mother has an appt with the neurologist next week so i await to hear what he says.....
