Nearly half of U.S. citizens over the age of 85 are suffering from some kind of dementia and require care. Loving Someone Who Has Dementia is a new kind of caregiving book. It's not about the usual techniques, but about how to manage on-going stress and grief. The book is for caregivers, family members, friends, neighbors as well as educators and professionals—anyone touched by the epidemic of dementia. Dr. Boss helps caregivers find hope in "ambiguous loss"—having a loved one both here and not here, physically present but psychologically absent.
