My parents are both 92 and live in their home independently. My Dad suffers from dementia. He is terrified of her as she emotionally abuses him if he goes against her wishes. He wants to see me, but I don't have any access to him. She does not allow him out of the house and won't let me in the house. He is a prisoner there. She doesn't talk to him if he tries to do anything that she hasn't approved. I want to see my father, especially because of his advanced age. I'm afraid she won't let me see him if he goes to the hospital or when he is dying. I spoke to APS, but they said that they can't "see" the kind of abuse I'm describing, so they can't do anything. Do I have any rights in this situation? He is under her control and is powerless.
Just to be sure I've understood you correctly: your father is living at his home with your mother. Two months ago he was diagnosed with dementia, but more recently was assessed as still having mental capacity. You are now hoping to arrange a further assessment.
Your mother, meanwhile, is undermining your efforts. But is it correct that she is your father's primary caregiver, and the one responsible for his welfare?
