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. Nine primary carers were interviewed using semi-structured one-to-one interviews. Interview data were analysed with inductive thematic analysis. 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.
