I live in Florida currently. My mother has dementia. I am the baby and have 2 older brothers, the oldest is with her now taking care of her. My middle brother and his wife were taking care of her a few years back before dementia has increased. Then she was of sound mind and made my middle brother her power of attorney for finances and health. She moved away from them because my brother's wife was over medicating her which made her very sick and my mother felt as though my middle brother's wife was trying to kill her. My mother was living on her for awhile but this last the dementia is increased. My oldest brother has been staying with her making sure she gets doctors appointments and food in the house and eating properly along with her medications. He is also the one whom has been paying her bills with her income. So the brother that currently has POA does nothing for her. How can we change the POA from middle brother and wife to oldest brother whom is with her 24/7 doing everything with me in the background assisting as much as possible over 1,200 miles away?
