Graham, you can explain, but people with Altzheimers rarely retain what you’ve said. I’ll give you an example. My relatives moved house after the husband was diagnosed with Altzheimers. He never understood that he had a new home, and worse still, he no longer recognised his wife because he thought she was still at the house they’d left and that the ‘lady’ in the new house had stolen all the ornaments and pictures (which he recognised) from the old house. He would go around collecting everything into a bag because they didn’t belong to the ‘lady’, and this former gentle man became quite dangerously aggressive towards her. He wouldn’t get into bed at night because this woman wasn’t his wife, and several times he went walkabout trying to find her, on one occasion disappearing for 18 hours. I would arrive at their house and he would be in tears begging me to help him find her. There was no alternative but to move him to a secure residential home – and he never recognised his wife again. He always thought she was still in the old house. Heart-breaking – and so hard for those of us who cared for him – and for her. I feel so sorry for you. I hope you find a solution.
