I don't think any of us can work out how a PWD's brain is working. If you've read any of Norm's thread, you will see that he suffers with torment and confusion, sadness and anger and much of the time he really struggles. Perhaps we shouldn't try to work it out but perhaps that for one little moment, whatever is happening in that person's mind, that is how it is and we should accept it for what it is. The next minute it could all change and then you are back to square one. If you want to know what is going on in someone's head because you are trying to anticipate what to do next then good luck with that. Just think about how hard it is to work out what is going on in a well person's head, and you will realise that it is just not really possible.
