Mom was diagnosed with dementia 2.5 years ago. Her short term memory is gone but she is still very pleasant. At times she asks what wrong with my memory. I tell her that she fell and hit her head a while ago and some of her memories have been affected which is how this all started. My sister ( who shares care with me) was told that we should tell her that she has dementia and that it is the disease that is causing her memory loss. The word dementia is very upsetting to her as she has had several friends go thru this terrible disease. My feeling is why upset her with this terminology. She accepts the fall and memory loss theory and moves on to other things. I know that she will not remember after a period of time so if I can keep her as happy as possible thats what I want to do. Any suggestions/opinions would be of great help. Thanks.
