Hi, Mary!I can't remember if I've used aimsena or not....Seriously, I have used PTSD in The Mysterious Miss M and am using it in this new book, currently (right this minute) in revisions. And I made the father in The Marriage Bargain have a sort of dementia. The challenge for me is to figure out what the medical terms would be during the early 1800s. A stroke would have been called "apoplexy" for example. To my knowledge, PTSD was not recognized until WWI, but surely it existed before then. I just have to imagine how my hero would think of what he experiences
