I've never read Still Alice (but now would like too), one that touched my heart was Memory Lessons by Jerald Winakur, he is a doctor that works with older patients and he also talks about his aging father in the book and his struggles, we think doctors know everything and are above it all but he casts a human shadow on that and I enjoy his perspective on it... one of those books that require kleenex but worth reading.
Elder Rage-Or Take My Father Please!: How to Survive Caring for Aging Parents - Jacqueline Marcell - alot of humor (used to describe a very difficult situation) and excellent advice. My father got a huge hug after my reading this because he can be obstinate and difficult, like most people that are cared for he definitely has his moments but he's never been quite that bad. Reading this book put things in perspective and she writes in that if we don't laugh kind of way...
Nasty, Brutish and Long:Adventures in Old Age and the World of Eldercare: Offers insight from someone who has aging parents and works in psychologist in nursing homes, I like this book because it brings insight on how Older people are feeling... I'm always trying to understand how it is for them... it makes it easier with Dad thinking about what his perspective on things might be, see both views with this book... I also like reading My Stroke of Insight:A Brain Scientists Personal Journey-Jill Bolte Taylor, it gives hope and further perspective.
But mostly on a bad day I like to read something like All I really need to know, I learned in kindergarten (Fulghum) because even if I'm crying I'll find at least one story in it that will reliably make me laugh and sometimes that break is really what we need.
