Summary
Early dementia diagnosis is essential for timely care planning and access to emerging disease-modifying therapies (DMTs). Blood-based biomarkers (BBBMs) offer a promising, less invasive diagnostic pathway. However, their real-world acceptability among those affected remains poorly understood. This qualitative study explored attitudes toward BBBM testing among three groups: people with dementia, carers, and older adults with subjective memory complaints. Twenty participants were recruited from community organisations and dementia support groups and interviewed using a semi-structured approach informed by the Theoretical Domains Framework. Reflexive thematic analysis identified meaningful variation across groups, spanning motivations for testing, concerns about accuracy, ethical implications, and strong preferences for in-person result disclosure with adequate follow-up support. Findings highlight barriers and facilitators to BBBM integration into routine clinical care, informing the development of person-centred implementation strategies that reflect the perspectives of those living with or at risk of dementia.
