Tefler, Talk about simplistic! "as long as she can still make decisions and sign her name"
I look after people with advanced dementia, who can make decisions and sign their name.
Some would also willingly give me every penny they possessed if I asked them. They know when they want to go to bed but if asked, will punch me if they dont (given the chance) will also remove clothing in the communal lounge a defecate on the floor. yet they can still make a decision and sign their name!
