The majority of patients with Alzheimer's disease are cared for by their families at home. Caring for someone with Alzheimer's disease is commonly portrayed in terms of 'problematic' behaviour. This study explored the level of understanding carers have of the illness and the psychosocial impacts carers experience. Qualitative interviews were conducted with eight carers who had been looking after their relatives in community settings. Findings suggest that the carers in this study have a distinct lack of knowledge regarding Alzheimer's disease and its management.
