Still Alice - Lisa Genova

Alice Howland is proud of the life she worked so hard to build. A Harvard professor, she has a successful husband and three grown children. When she begins to grow forgetful, she dismisses it for as long as she can, but when she gets lost in her own neighbourhood she knows that something has gone terribly wrong. She finds herself in the rapidly downward spiral of Alzheimer's Disease. She is fifty years old.
Suddenly she has no classes to teach, no new research to conduct, no invited lectures to give. Ever again. Unable to work, read and, increasingly, take care of herself, Alice struggles to find meaning and purpose in her everyday life as her concept of self gradually slips away. But Alice is a remarkable woman, and her family, yoked by history and DNA and love, discover more about her and about each other, in their quest to keep the Alice they know for as long as possible.
Losing her yesterdays, her short-term memory hanging on by a couple of frayed threads, she is living in the moment, living for each day. But she is still Alice.
