Dementia is a term used to describe a collection of symptoms that include problems with memory, self-care, reasoning and communication. Care interventions that focus on preserving people’s dignity and identity are therefore essential. Using Driscoll’s reflective model to guide critical thinking, this article reflects on the use of one intervention, namely life story work, to promote person-centred care for people with dementia. It explores the value or effect of life story work for healthcare staff, the person with dementia and family members. It also highlights best practice guidelines that are useful to consider to promote its optimal success as an intervention in dementia care, for example, instigating it early in the dementia journey and embedding it in a supportive culture. It is important to highlight to nursing students the many positive aspects of incorporating life story work into practice.
