I'm a full time carer for my uncle who has end stage parkinsons, been caring for him for 18 months now.
I also care for my aunt who has severe alzheimers, I'm not officially her carer as one person can only be a registered carer for one person even though I do care for her aswell.

luckily she goes into day care 5 days a week, 10-4, a real godsend as shes a real handfull, she crys most of the time... when she's not sleeping that is.
As for homes, cant say I like them.
My other aunt sufferend when she was put into a home, she eventually died from neglect, her feet got infected of all things.
I put my aunt with alzhemiers into repsite for a week and she caught a nasty bug, in the end she was even put on a drip!
Everytime she goes into a home for a break she comes out worse.
As far as it being the families duty...... na
If I had my time to go over I wouldnt have stopped work to care for them. Carer's DONT get the credit they deserve, its hell, especially when the relatives are particualarly dependant like mine.
