"You cannot restore someone to their Connection with Source by belittling them or by punishing them, or by being disgusted with them. It is only through love that you can return anyone to love. And if you do not have a way of returning them to love, they will always be a problem to your society." Abraham

In the above context, Abraham is talking about the way we treat criminals; but the same could be be said for people with any disability -- to include dementia.  People rarely ask me how my husband is doing -- I think because they are uncomfortable with the subject.  In restaurants people have sometimes been obviously uncomfortable with the difficulty he has eating.  I think ageism is still very much a factor in our society, especially if the older person also has some limitations.  As caregivers, we can model treating the person with dementia with respect.  It would only take a blow to the head, and any one of us could be in a similar position.
