When do you have a "loved-one" declared incapable of making decisions for themself? Is it reasonable to declare someone of unsound mind when they refuse medical treatment? At what point are you held responsible for someone's demise due to their own refusal for treatment? My dad is at it again. Mom called to say his leg edema is worse than she's ever seen it (he's already on diuretics and various other medications for his congestive heart failure), and to top things off, he now runs a low grade fever that spikes over 100 and he has a rash that is spreading from his legs on up. I'm thinking cellulitis, or maybe worse. He refuses to let her call the doctor and he certainly won't call the doctor on his own. She's tired of hearing him complain and obsess about the problem and not do anything about it, and get mad at her for even suggesting something be done about it. Is she to be held responsible for his refusal to seek help? At what point can/should she legally intervene and have him declared incompetent? I know he's scared and that's why he's such and SOB. But I also feel for my mom in this position. Any advice for her? Besides the divorce she should have filed for decades ago?
