This book approaches dementia from a number of angles: biological, psychological, sociological, and theological. After an introduction explaining the multifaceted nature of this set of conditions, some possible theological responses are offered to such questions as: what is the nature of human identity? How can someone with severely impaired cognition have a full spiritual life? The book's final two sections are predominantly practical, addressing the spiritual care of the affected individual and how to help churches support affected individuals and their carers. This final section includes resources for ministry in residential care homes.
