while it is true that there is no official diagnosis, she has so many of the symptoms. she has poor short-term memory, repeats things over and over ... it is basically the same story again and again. Her memories of the past are like stories that never happened or part is true linked with something untrue. She accuses people of stealing, is agitated, etc. she has even hallucinaated a couple of times. Docs said she has cognitive impairment, then that she has sundowners ... but never say it is dementia. Feel like I am the only one seeing this and makes me feel guilty too. Of course, I dont want this to be happening, but I cannot help seeing what I see. My sisters say it is "just old age". She is 90.
