She did not know what she was signing and he did this to keep her out of a nursing home. Other siblings take her food, try to see her each day but she is becoming more and more unsafe to be left alone. She has already broken a hip once. She is halucinading at night and wont take her meds. He won't stay with her or take a turn in caregiving. She requires 24 hour care for bathing, eating, meds, dressing and keeping her from falling again. We had to turn off the microwave, stove, and other dangerous items in the home. She sits right beside the phone but cannot hear it if someome calls to check on her. My brother with the power of attorney wants to do what ever she says. He states there is nothing wrong with her. How do we get her help now?
