Introduction Research has shown that approximately 67% of carers experience extreme mental tiredness, a decrease in their quality of life and a deterioration in their physical health since taking on a care-giving role. Aims and objectives This study aims to identify factors that influence carer burden and in doing so, identify the sub-populations of carers who are most susceptible to burden. Methods In northwest Ireland, 53 informal carers referred to the Carers Association, Sligo were contacted and met for a face-to-face interview.
