Aims and objectives: To identify preclinical signs of dementia by exploring the experiences of family caregivers and professional care assistants. Background: Dementia results in disability, emotional strain and financial loss for people with dementia, family members and nations. Informal identification of social and behavioural risk signifiers could facilitate timely interventions with potential to delay onset of serious disability. Design: A retrospective qualitative approach using a naturalistic interpretive design was used.
