I live with my mom who requires 24x7 care due to dementia and mobility issues. My older brother holds power of attorney for health and continues to avoid providing me with her after visit dr summaries. He also avoids providing notification to me when she has upcoming doctor appointments. I work full-time and my mom has an outside caregiver come to the house while I am at work. I had to take my mom to urgent care on Saturday due to bloody discharge coming from her ear. My brother took my mom back to her primary care doctor on Monday and the caregiver verbally let me know that her meds had changed. I was confused and sent a message to my brother for confirmation. He refused to answer my text. This isn't the first time this has happened. I am frustrated. The relationship between my brother and myself has become stressful for various reasons. I've stated to him over and over that while our relationship is not the greatest communication regarding my mom's health is important. I am looking for advice on how to deal with him. Thanks.
