I have observed that the general public still has very little understanding of mental health problems and how to react when told that a person is suffering. Many mental health problems are not treatable with drugs, yet some folks try to force mental health issues into solutions similar to physical health solutions. Additionally, some folks tend to comment on solutions rather than simply offering their compassion. I think this is because of their unfamiliarity and the topic makes them uncomfortable.
My mother-in-law died of a form a severe dementia. Now my wife (who is 65) is on the same road as her mother. She is scared about her future prospects, but also worries about the embarrassment if she forgets something in general conversation or loses track of the conversation altogether. As a result, she hides her condition as much as possible but lives in fear of screwing up and exposing her condition. The worst thing she fears are the words, you already said that. That happened at her college reunion and, sadly, was uttered by a long-time friend, even after my wife admitted she had been having cognitive changes in recent years. People just don?t understand and don?t know how to deal with it, even when told in advance.
