Query: Most disappointing

The cover of this book gave me reason to expect that it would focus on the story of a family afflicted with Alzheimer's disease and the transmission of the disease through the generations. Instead, the majority of the book reads like a gigantic journal article. The author (a doctor) throws in a mere smattering of human interest here and there, but it's simply not enough to make the story interesting. I am not incapable of reading scientific writing, but page after page of it, as if it were a story in itself, is incredibly tedious.
