My Mother in law is showing definite signs of early dementia compounded by alcohol use. She is increasingly irrational and abusive to everyone in the family. My Father in law is having a hard time coping and we are not sure what to do. We have pushed for doctors (even rehab) but she gets extremely angry and FIL immediately backs down. We unfortunately (or thankfully) live far from them but are in daily contact. At a loss for what to do or how to help. Where do adult children go to guidance for situations like this?
