In this chapter, we will outline the different settings in which people with dementia receive care. Because the services that are recruited and the decisions that are required to be made will often correlate with the severity of dementia, we will give an outline of the different stages of dementia (particularly as they apply to Alzheimer’s disease). We will discuss the prognosis of dementia, given its importance in a legal and clinical context, before outlining the elements of services for dementia, as well as the principles that should be applied in delivering care. We will then outline some of the ethical issues that arise in practice, but we will explore more specifically how these three statutes relate to the range of situations that arise over the succeeding chapters.
