My husband lives with his elderly parents: father has arthritis, heart disease, and other issues but not dementia; mother is in late stages of Alzheimer's disease. Lately, during our infrequent conversations (my husband rarely initiates or responds to communications), my husband has described to me his mother's recent sharp decline. He has not taken her to the doctor. He has not called the doctor. He has not talked to his siblings. He and his father are doing everything on their own. From what my husband has said, I think my mother-in-law might be actively dying and I think the siblings should be told so that they can decide what, if anything, to do: visit; call; pray; whatever. I'd appreciate any thoughts about what, if anything, I should do. Thank you.
