Click here to see a review of a book called The Long Hello: Memory, My Mother, and Me by Cathie Borrie. I found this review on an excellent blog called The Generation Above Me. Here is an excerpt from the book review:
Borrie perceives her mother to have richness and insight borne out of her mother's mixed diagnosis of Parkinson's Disease and Alzheimer's Disease. To emphasize the point: she's implying that it's because of her diagnosis not despite of it. Her mother's guard comes down, revealing more raw emotion and more blunt opinions. Her mother's language doesn't decay for Borrie; it transforms.
Borrie's writing style also extends beyond prose. She includes a number of exchanges between herself and her mother. But this isn't strict dialogue--it's poetry.
