For a few years now, my mother has noticed a decline in my 78-year-old father’s mental health. The signs all point to dementia but she doesn’t know how to persuade him to see their GP. He can be aggressive and volatile and this isn’t a conversation she seems able to have. Does anyone have any tips? I live overseas and am unable to travel at the moment. I am concerned about my mother as well. She says the situation is just “something she has to manage” but it’s tough without any support.
