Mum had a doctor testing her memory etc yesterday. They (according to my dad) clearly said she didn't have Alzheimers because she was able to remember, when prompted, some words that were said earlier in the session. According to that particular doctor there is no way that she could remember, even if prompted, if she had alzheimers. Forgive my cynicism, but if it was that easy to tell, surely no-one would be looking on this website?!
They did say she had problems with procedural memory and was probably in the early stages of vascular dementia (which does confirm what I thought anyhow). If the memory test doc writes to mum's doc with her report, would that make anything (e.g. will, PoA forms) mum signs from now on not valid?
