Aren't you all sick of my infernal questions already?! I was wondering how easy other people have found it getting a firm diagnosis? We're currently finding it very difficult. Our GP believes that mum has AZ or semantic dementia and wanted her to have a brain scan which she is refusing to consent to (we think - she gets confused between "yes" and "no" but I think in this case she is on a definite "no"). Dad managed to get her to an assessment set up by our GP but the first time he said he was busy and told her to keep a diary - a fine feat for a woman who can't speak and gets confused writing. The second appointment he refused to speak to my dad, took mum in a room by herself and then declared she had a "block". We have no idea what went on in the room because obviously mum is unable to tell us. We've now asked for a referral to someone else for a second opinion but I'm worried about the same thing happening again and to be honest my dad's at boiling point over the whole thing as mum is starting to go down hill very quickly (she no longer understands money, can't cook or follow simple instructions and insists on visiting Tesco several times a day). Can we get a diagnosis just from these assessments or is a brain scan necessary at some point?
