My mom has moved in with my sister in the south and plans to live with me in the north in the summers. She has only recently sought help for her memory issues, which became significantly worse after the very traumatic loss of my dad in an accident. I believe she has PTSD and am trying to steer her to help for it. She gets confused about time and place in particular, and we are concerned that having two "homes" will make her confusion worse. My home is more conducive to her lifestyle (quiet, small town), but my winters are too much for her. My sister's home is busier and in a big city, but the summers are oppressive. She had been living alone in a more temperate place but had isolated herself, so we convinced her to live with us. I'd love to learn from all of you about how to make this scenario work for her.
