I am my mother's POA and Healthcare proxy. My brother who lives near her, never visits but claims he does. I know this is a lie and that's why I'm now fighting to bring her home. He's supposed to be looking after her, since he lives 1/2 mile away and I'm in another state. When I call, I ask the nurses if anyone has visited my mother and they are telling me that they cannot tell me if anyone has visited her...is this true? My mom has dementia and cannot speak for herself.
