I salute the author for clearly showing us the horrifying way in which the disease takes away personhood from a person, even if the person may not be aware of this progressive mental and physical loss. The author described in detail how the long stretch of 7 years actually was, for caregivers, who had to deal with the lack of useful general information, support, institutions, legal information or social structure. I loved how the author seamlessly moved from culture to culture, through different timelines from chapter to chapter. Such visual, visceral and gut-wrenching narration was helpful for us to comprehend the magnitude of difficulties siblings might need to grapple through. It was so helpful to know the different types of memories and where they reside. I feel that the author gave many readers much needed permission to act. We lay people now know how the role amygdala, hippocampus, frontal lobes and other areas play in memory, anger, emotion or lack thereof as the disease progresses. Thank you!
