hello
@Mcguvern
welcome to TP
you've packed a lot into your post, so I'm not sure I have the situation clearly
your mum has a house in Ireland (Republic of not Northern) which she was living in until recently with her partner (not spouse) - she is currently in Essex with her son, staying with him as a visitor rather than having moved in with him
she is saying she wants to go home but, as with many with dementia, her meaning of home is the safety of her childhood home with her parents rather than the property she owns
is she then Irish rather than British? - I ask as this may affect her qualification for benefits etc in Essex
you say she has no money, as in cash and savings, but owns a property - I assume her partner is still living in the property
in England this might well make her self-funding when considering residential care, depending on the rights of her partner to remain there
I do think, as far as finances go especially, you need some specific info - it may well be worth calling the AS helpline as the folk there may be able to direct you to helpful organisations
https://www.alzheimers.org.uk/get-support/national-dementia-helpline
as you are your mum's Attorney, you are in a position to take on the management of her finances and also, if you believe that she no longer has capacity to make decisions for herself, to make arrangements for her welfare, including organising a move to residential care, especially if she has funds to pay the fees
if she hasn't then you do need to contact the Local Authority Adult Services where she is in Essex to have an assessment of her care needs - from this a care package will be suggested which could include home care visits (if your brother intends to have her live with him permanently) - however, I don't know how her Irish residency affects this
is her GP in Ireland or has she been registered with one in Essex?
you mention that you're not sure how to deal with the wandering etc - it is probably not effective to reason with your mum, as the dementia will probably have affected the parts of her brain that help her to reason, instead reassure her and distract her - some of the strategies on this thread may be of help

another source of support is Admiral Nurses

and try your local AgeUK
the main AS site has a directory of local services

I hope this is of some help
do post again with anything that's on your mind
