One of my uncles, my brother and I think my grandmother is in the early stages of Alzheimer's. We can't get her to go to a doctor and no one else in my family really talks (my other aunt or uncle nor my mom). So don't know what to do and I'm really worried about her. She just turned 72. Anyone else been through this??
