Background: The improvement of care in patients with dementia remains a priority in various healthcare systems; an assessment of effectiveness for available interventions for this heterogeneous disease remains a concern. Life Story Work (LSW) is a non-pharmacological intervention that focuses on the importance of listening to and understanding the patient via their life stories; its application (in care settings) is based on the principle of valuing the diversity of patient life experiences and celebrating the individuality of each patient.Objectives: The key research questions explored are: 1) How LSW is employed in dementia care and 2) The effectiveness (including sustainability of effect) of LSW in the reduction of cognitive impairment in elderly people living with dementia.Methods: A systematic literature review was conducted using studies identified within the following databases: Scopus, PubMed, PsycINFO, CINAHL and the Cochrane Library in addition to manual searches of studies referenced in included studies.Results: Emerging themes include problematic recounting of chronological recounting of events, timing of the commencement of LSW as an intervention, the format of LSW, technological literacy, capacity of care workers in the care setting for LSW, dissociation between cognitive improvement and sense of well-being, trade-off between LSW effectiveness and cost of implementing LSW, patient-centered vs care worker-centered LSW.Conclusions: LSW can help individuals with dementia enhance their quality of life by developing a sense of identity, increasing communication skills, providing person-centered care, engaging family members and caregivers, and creating a pleasant care environment.
