The memory of all that : a love story about Alzheimer's / Mary MacCracken.

Enhanced descriptions from Syndetics:

From the award-winning bestselling author of books about autistic and learning-disabled children, Mary MacCracken, comes an engaging memoir of love, marriage--and Alzheimer's. Braving divorce to be together, Cal and Mary help each other overcome setbacks in their work. Cal's inventions are increasingly successful; Mary's first book is published to much acclaim, followed by three more. It seems nothing can stop them.

Then Alzheimer's strikes. Always a fighter, Cal vows to beat his disease, while Mary finds ways to sustain their loving life together, devising ways to help Cal as he falters. She herself is helped by good doctors, social workers, and many friends--a whole community of care.

Still, all the support in the world can't stop Cal's decline. He goes missing at night, flees his daycare program repeatedly, and must finally go to a memory unit. But even then, he and Mary share bits of happiness. In the end, they fail to beat Alzheimer's. Yet their story is also one of triumph, as their love persists all through and beyond their battle.

Poignant and inspiring, The Memory of All That is a beautifully written love story that offers guidance and comfort to those dealing with dementia, or any of life's challenges.
