This presentation explores the development and presentation of A Box of Memories, an original documentary musical that uses story, music, and theatre to promote person-centred care for people living with dementia. Co-created by a daughter-father creative team, the work draws on lived experience and clinical insight to illuminate emotional, relational and systemic dimensions of dementia care. The musical follows three characters: Lizzy, a woman navigating the challenges of diagnosis and change; Sonia, her daughter grappling with caregiving and grief; and Jeremy, a medical specialist rediscovering empathy through his engagement with Lizzy’s story and experience. Through these intersecting narratives, the show invites audiences to reflect on their own relationships with dementia, whether personal, professional, or societal. Using performance video extracts and behind-the-scenes reflections, the presentation will illustrate how the show’s autoethnographic practice fosters emotional resonance and audience identification to promote attitudinal transformation. The presentation will also provide insights from audience evaluations demonstrating the show’s efficacy in shifting perspectives on dementia, personhood and care. By integrating artistic practice with clinical and community engagement, A Box of Memories demonstrates how documentary musical theatre can be a powerful tool for raising awareness, challenging stigma, and cultivating empathy, promoting greater person-centredness in care for people vulnerable to marginalisation. This session will be of interest to creative and health practitioners, researchers, and advocates seeking innovative approaches to person-centred practice. It will offer insights into the potential of the arts to transform attitudes and deepen understanding of complex human needs, leading to greater application of person-centred philosophy and practice.
