Living with a person with dementia considerably affects the lives of both the primary caregiver and the entire family. This study aimed to synthesize the findings of qualitative studies that explored dementia caregivers' experiences, to further understand the impact of dementia caregiving on family dynamics. Thirty-seven qualitative studies were analyzed and synthesized according to the meta-synthesis methods suggested by Sandelowski and Barroso. Four themes were identified to describe the impact of dementia caregiving on the family: cracked foundation of the family caused by dementia, voluntary or involuntary setup of a marked boundary of care, family as supportive foreground versus reluctant or interfering background, and re-established relationships within and outside the family. The findings illuminate that dementia caregiving has a destructive impact on the entire family, and therefore, it is imperative to develop interventions and infrastructures for both the caregiver and the entire family of individuals with dementia.
