My older relative has been in full care for more than a year. He is always happy to see me and knows who I am. He also remembers other relatives. I have been told by other family members that he forgets about our visits moments after we leave and that there is no need for me to feel guilty for not visiting more frequently. He has never said so himself, but I still find it difficult to not be there more often. I have seen him before he knows I am there and he always looks as if he is okay and not lonely, but after a visit he never wants me to leave. It is very sad.
Is this common?
