I read Still Alice during this fall's readathon and holy wow that's a good book. I've just recently also read Left Neglected by Genova and it seems to be a common denominator for her to write excellently about brain damage.
What's so brilliant about this book besides the whole extremely well written and engaging part, is the fact that it teaches the reader a lot about life, about coping with a life-altering disease such as Alzheimer's and about Alzheimer's in general. About how you're still you deep down, even if your body and your brain don't allow you to express that anymore. About how Alice was Still Alice.
The book also beautifully portrays how the world around an Alzheimer's patient reacts. How even though it's only in the early onset stages people start to withdraw, because they don't understand or aren't willing to. Friends and co-workers unable to handle the changes. How the family reacts. The children worrying they'll get it too through genetics. The husband suddenly faced with being married to an entirely different person than the intelligent career woman he fell in love with. But Alice is still Alice, deep down, and she's just as frustrated as every body else.
Read this book before you forget.
