My father passed away in 2008, and since then I have watched over my mother's affairs. She lived on her own in Florida until 2013, when I moved her to an assisted living near me. She has macular degeneration and hearing loss, so she has become more isolated because of that She has also shown more signs of dementia - memory loss, obsession with sorting her clothes, believing someone has stolen clothing she never had. This obsession is fairly recent. She can carry on a conversation with you when she is focused and not tired. She takes care of herself, dresses herself, keeps her room clean, irons her clothes, etc. I believe that her failing eyesight and hearing have exacerbated her dementia. I've never had her diagnosed. We feel it is probably vascular dementia as she has had a heart attack, 5 by-passes, several stints, a stroke, and probably several TIAs. Her carotid arteries are 90% blocked, but the doctor and I agree that operating would be more dangerous than letting her go as long as there are no symptoms causing her pain. My biggest question is whether I should have her see a doctor and get a diagonis as to what kind of dementia she has just in case it is treatable. She will be 93 next week and against having any agressive medical treatments to prolong her life.
