My 97 year old father is and always has been verbally and emotionally abusive, especially with my sister. He is narcisistic and now in his old age, he cannot stop talking about all of his great achievements and he exaggerates stories about famous to make himself look important. It's hard to hear, and he has lived alone as a result, but now, as he approaches the century mark, and my sister is the primary caretaker because I still work, he has turned on me. He tells my sister that she needs to take care that I don't cheat her, and he is accusing me of stealing from him. I have left his house in tears. He makes a point to ignore me, hangs up on me when I call, and my sister shouldn't have to have all of this on her shoulders. He has always told us that we were worthless, and he wants our children to care for him, which they obviously won't. Though he's always been abusive, we think he may be developing Alzheimer's. Does this sound like it?
