Individuals with dementia with Lewy bodies (DLB) commonly die from dementia-related causes, but little is known regarding caregiver experiences during the end-of-life period in DLB. This reflects a critical knowledge gap given the high frequency of informal caregiving for individuals with dementia, high caregiver burden in DLB, and the fact that most individuals with DLB die from this disease. Investigators conducted telephone interviews with family members of individuals who died with DLB in the last 5 years. Investigators used a qualitative descriptive approach to analyze interview transcripts. Participants included 15 children, 13 spouses, and 2 other family members. Interviews averaged 31 min. Major themes included caregivers as the main drivers of care for individuals with DLB throughout the disease course and at the end of life, the impact of DLB features (e.g., fluctuations, hallucinations, and delusions) on end-of-life experiences, experiences relating to the caregiving role, death and post-death experiences, and supports employed by caregivers in the end-of-life period. End-of-life experiences for caregivers of individuals with DLB built on the accumulated burden of the disease course, where caregivers were often responsible for driving DLB care—from making the diagnosis to educating healthcare professionals and double-checking medical decisions. While some end-of-life experiences were consistent with those described in dementia palliative care more generally (e.g., financial stresses, poor sleep, being overwhelmed, and needing increased education and support), many DLB features specifically affected end-of-life caregiver experiences, such as the presence of delusions. Improving caregiver experiences at the end of life in DLB will require improved diagnosis and care for individuals with DLB throughout the disease course and also better strategies for treating behavioral symptoms. More research is needed regarding drivers of quality end-of-life experiences for individuals with DLB and their families and how drivers and strategies may differ between dementias.
