How do you continue to find God as dementia pulls your loved one into the darkness? Nothing is simple for a person suffering from dementia, and for those they love. When ordinary tasks of communication, such as using a phone, become complex, then difficult, and then impossible, isolation becomes inevitable. Helping becomes excruciating. In these pages philosopher Douglas Groothuis offers a window into his experience of caring for his wife as a rare form of dementia ravages her once-brilliant mind and eliminates her once-stellar verbal acuity. Mixing personal narrative with spiritual insight, he captures moments of lament as well as philosophical and theological reflection. Brief interludes provide poignant pictures of life inside the Groothuis household, and we meet a parade of caregivers, including a very skilled companion dog. Losses for both Doug and Becky come daily, and his questions for God multiply as he navigates the descending darkness. Here is a frank exploration of how one continues to find God in the twilight.
