It is estimated that 1.2 million Australians are currently caring for someone with dementia. Caring for somebody with dementia can become more complicated by the presence of behavioural problems (e.g. depression, anxiety, apathy, aggression) in the person with dementia. These behavioural problems can contribute significantly to carer burden and distress. This study aims to improve our understanding of how interactions between the carer and the care-recipient affect behavioural problems in dementia. A better understanding of these interactions will help us develop programmes which can be used to assist the carer and those suffering from dementia to minimise the negative impact of problem behaviours in dementia.
