So mum's been ridiculously confused since staying with me. Spoke to her doctor who informs me that it's probably connected to unfamiliar surroundings. Managed to speak to my brother (who lives with her and is her carer) even though this was a difficult thing for me to do. He will not accept any help that maybe available to them but expects me, who lives one hour away, to help. He says he's coping, I say he's not and needs help in the home. I'm taking mum back home tomorrow with my husband in tow as I don't trust my brother to not 'kick off'. I'm having to just accept that there is nothing I can do to help until he realises he can't cope on his own.
