This primarily includes attachment, meaning the close relationship with familiar individuals. The author clearly explains how to make attachment experiences fruitful in working with people with dementia. Numerous case studies illustrate how attachment disorders affect coping with the illness and how to identify protective factors in the individual's biography.
