He had cardiac arrest on 3/27/2018, and went without oxygen and it caused a stroke and also shut down his kidneys. Fortunately, he did not suffer from paralysis or any speech impairment. His motor skills are just slower. My main concern is this. My other brother became his medical power of attorney. He is extremely controlling. He believes that he has all rights to make all medical decisions for him. This includes choosing his family doctor and matthew is not comfortable with the physician. POA also wants to change or alter one of his medicines, even though he does not want to change or alter it. If he is able to make decisions on his own, why can't he? He actually is afraid to say anything to any healthcare staff because POA goes into every examination with him, and speaks for matt. Matt wants to talk to doctors to tell them this, but POA is always there. He gets no privacy. Matthew feels awkward because POA has given him a place to live and has kept him from being in poverty. But that doesn't make it right. What can I do? I truly believe that matthew knows that i have his best interest in mind and he trusts me. I need advice. Can anyone clarify the medical POA for me. It doesn't make since to not let a human make a decision if he is able to.
