Background: Ageing is a significant risk factor for developing dementia; however, some people develop symptoms before the age of 65. Although less common, it is referred to as young-onset dementia. Estimating prevalence rates in Ireland is difficult, as there has been little study around what it is like to live with/care for this cohort; consequently, it is poorly understood. Methods: Nine primary carers were interviewed using semi-structured one-to-one interviews. Interview data were analysed with inductive thematic analysis. Findings: Themes included sense of loss, diagnostic issues, appropriateness of services, stigma and carer strain, illustrating the complex nature of caring for someone with young-onset dementia.
