My dad has been in a veteran's home for a year now. He has dementia. His personality has not changed. He seems sad sometimes. Will he change? My mom died 3 years ago and I never seen him grieve. He got lonely. She had very agressive alzeimer's and he took care of her with some help until the end. I am so afraid he will be mad at me for not being able to take care of him. He started leaving the house. The home takes very good care of him. He has diabetes and just had a tumor removed from his bladder o stage cancer(thank god) he is 81 years old.
