Hi, I am the caregiver for my 85 year old father with dementia. My husband and I moved in with him a little over 7 months ago. He either doesn’t realize he has dementia ( even though he has been on medication for several years), or he is in denial. My father has never been a talker; so, knowing whether he knows or not has not been verbalized by him. I don’t know if I need to discuss it with him, or if it would be harmful to do so. There are things I feel I need to discuss with him, because he is quite resistant at times with receiving assistance.
