Hello, My step-dad was diagnosed with dimentia/alzheimer's recently. My mom is 57 and he is 74. She has had to put him in an assisted living facility because of his constant aggression. They have been married 21 years and she is now having to deal with all the negatives with my step brothers and sisters. They have always been so supportive and loving to her until now. What can she do to get them off her back.
