Perhaps they are acutely unaware of their own neurological degeneration.
Stroke or not, It is only through writing (be it personal musings, or the fiction that I have been exploring more recently) I see that I grow incredibly on a cognitive level the more I read and write. (Creatine probably also helps!) In the last 6 months or so where I have really increased my writing volume and reading volume, I have had such increased self satisfaction.
I can write about the things that would have before seen me be depressed for week, and instead, they might have the effect of depressing others.
That is what good writing is. :D
Isn't it great? Being creative is where it is.
Ha! I think you are on to something with this.
