Impact of dementia on informal care: a systematic review of family caregivers' perceptions.

The findings provide insights into the holistic experience of caring for a person with dementia revelling the major positive and negative aspects underlying the caregiver role. The evidence emphasises the need 'to focus on positive aspects' and targeted interventions aimed at reducing the negative impact of caregiving, which has serious consequences on caregivers' quality of life. A multicomplex intervention for dementia informal caregiving should be developed, committing the society to promote mental health, address these community needs and improve the quality of life of the person with dementia and their family caregivers.
