My Mum was diagnosed with AD 5 years ago following emergency surgery and depression. Her post op recovery was slow and her short term memory was very poor. Prior to all of this her CPN had spoken to me about Mum's forgetfulness and the fact that she had very little food in the house. Mum had never been fond of cooking or cleaning more a sort of dancing and make up kinda gal so I thought nothing of it. Her memory got so bad and her mood so low that she came to live with me and has done really well. She is on anti depressants and Aricept 10mg. Her Consultant at memory clinic now doubts the diagnosis as her MMSE scores in 5 years have ranged tween 20/30-28/30. Last score being 23/30 recently. He said decline would have showed itself by now and he is confused. Mum remembers the questions she will be asked and rehearses them on the drive there. - What town are we in? What's the date? What floor are we on? What season is it? However when he explained to her he doubted the AD diagnosis I could see she didn't understand and so I asked her, in front of the Dr 'what did he say' she replied I don't know but got it after it was explained 5 times. Has anyone experienced this? He suggested further tests but Mum doesn't want these. Perhaps wrongly but I feel angry that the difficult times we have had with her and still do from time to time may not be AD but depression or bloody mindedness which has seen me in tears of frustration and despair. He said her problems may just be from old age but does your mind deteriorate just because its old? Surely deterioration is down to some organic cause where the brain is compromised by disease or deterioration of structure? Would really like to know how many people have had the medics doubt original diagnosis.
