The current review sought to summarise the psychosocial needs reported by people with dementia who live alone.

Eligible articles explored the needs or experiences of people with dementia living alone through qualitative or mixed methods.

Needs were identified across all domains of Kitwood's model; love, identity, attachment, inclusion, occupation and comfort. The data revealed overlapping needs between those with dementia who live alone and those who live with others but importantly, needs that were distinct or exacerbated by living alone with dementia. Specifically, threat to personhood without others to maintain stories about identity and the management of living at home with the recognition that this would eventually end. The heterogeneity of people with dementia who live alone was highlighted and the gaps in the representation of the needs of specific groups in the research were considered such as individuals from the LGBTQ + community.

Dementia care thus often includes the person with dementia, their carer, and their healthcare professional (HCP): a dementia care triad. Understanding how this triad is developed and navigated may improve future dementia care services. <b>Methods:</b> A longitudinal qualitative approach was used to interview 30 people with dementia, 31 family carers, and 7 healthcare professionals in England between May 2020 and March 2021. Data from three interview time points were transcribed and analysed using reflexive thematic analysis. <b>Findings:</b> The relationships within a dementia care triad were initially built on the dyadic relationship between the person with dementia and their family carer and any pre-existing relationships with their HCP. The nature and proximity of the carer to the person with dementia influenced how triadic relationships in dementia care formed and functioned, with spousal and co-resident carers more actively involved in healthcare interactions. Further positive development of a triad required confidence in the HCP, and shared perspectives on balancing the involvement of the carer and the independence of the person with dementia, with considerations of autonomy and risk, and which did not always follow a linear transition. While increased carer involvement often supported the person with dementia, it sometimes led to their exclusion. Engagement by healthcare professionals varied, reflecting inconsistencies in applying person-centred care. <b>Conclusions:</b> The findings of this study suggest a need for clearer, more consistent approaches that support dynamic carer roles while preserving the autonomy of the person with dementia.
