Dementia: a specter that haunts many, either as a fear for the future or as lived reality with a loved one. It has been called the “theological disease” because it affects so much of how we define our humanity: language, long-term memory, and ability to plan the future. The church has a role in bringing hope and shepherding the spiritual journeys of people with dementia and their families. Beginning with current theological models of personhood, concepts about the self and spirituality are explored through the latest research in medicine and neuroscience as well as from work on spirituality and aging. The final chapter focuses on narratives of successful programs in churches and retirement communities designed to minister to people with dementia alongside their families and caregivers.
