Mom is 92. She was diagnosed with a benign brain tumor, and dementia in 2014. She can no longer dress herself, think logically, go to the bathroom by herself, or carry on a conversation. My sister, aunt (whose 82), and myself have taken care of her. I’m ready to put Mom in a memory care facility. My sister is against it. How can I convince her it’s time? We have been taking care of her in her home.
