The perspective of people with dementia, particularly late-stage dementia, is often excluded from research, even from methods like Participatory Action Research (PAR), which aim to democratise research. This research note outlines how a PAR project engaged with the perspective of people with late-stage dementia in a residential aged care facility. Firstly, we focus on our mistakes: methods which did not appropriately include or engage this group. Secondly, we explore how methods drawn from design thinking, creative and arts-based research were used to encourage staff and families to think about the perspective of people with dementia. Finally, we explain how only after this extensive creative consultation and through a partnership with a social enterprise was the PAR project able to engage people with late-stage dementia in meaningful ways.
