Oh Astrid, that's so sad about your mum. My Grandma had alzheimers too. It was hard because we were so close and she slipped away a little bit at a time. She wasn't NPD though but did start to show some narcissistic traits but I think that was about survival. She wasn't mean but was very self focussed, I think she just had no idea what was going on. But I understand how hard it can be to see someone you love struggle with losing their memory (and pretty much their mind).

The link between alzheimers and NPD is interesting. I read somewhere that alzeheimers and age often cause the NPD to become more obvious because they lose all their inhabitions and forget about the little social ettiquette that they do have and so what they are really thinking becomes more obvious. I haven't had any personal experience with it but I thought it was an interesting article.
