This is more a question borne of frustration then of me expecting an answer. It seems like selective dementia at times, but I know this happens to other caregivers as well. Our loved ones can’t remember that they just ate once the plate is gone, nor that you are answering the question he/she just asked you because the question no longer exists in the memory of our loved one. However, if our loved one gets upset with us, all kinds of nasty words come flooding back and are spewed at us over and over again. It seems that upsetting thoughts stick in the mind of our loved ones for hours or even days at times. Happy thoughts though seem to come and go as quickly as they came. What is going on????
