The cornerstone of dementia care is social care, and much of this is delivered by the families and carers of people with dementia. The management of dementia should therefore focus on supporting and developing the care provided by family members and carers in the community, because their education and enablement will help to optimize the quality of life for all people living with dementia. This chapter concentrates on the assessment and management of people with dementia in the early and later stages of the disorder. At both stages we consider engagement, autonomy, respect, protection, and ethical issues, as well as describing the clinical and psychosocial aspects of treatment. The emphasis is on the broader principles of management, which apply to people with dementia of any aetiology, their families, carers, and communities, and take into account the different settings in which they may present.
