My mother has advanced dementia. She is 86. I took her to the dr. Same dr she has had for over 30 years. I had a detailed list of her current health problems and new anxiety and phobias. He did routine labs and EKG. Refused to acknowledge the other issues and treat her with meds. Said I didn't have medical poa and since mom said she was fine, he couldn't take my word for it. Using Hippa law as reason. What should I do? It is an ordeal to get her to a dr .
