In a chapter on prevalence of dementia, new estimates of dementia are presented. By disaggregating the prevalence estimates by gender, age, disability and ethnicity, the chapter highlights people with dementia as a diverse group of people. The chapter on informal caregiving estimates that over 60,000 informal carers of people with dementia living in the community and discusses how and why family members become carers, the significant contribution they make and want to make, but also want this to be recognised by way of regular formal support services or cash benefits. A chapter on models of care addresses important questions about how dementia is framed and the model that should underpin future policy on dementia in Ireland. The personalisation of services for people with dementia, education and post-diagnostic supports are the subject of the next three chapters. The chapter on the economics and financing of dementia care brings together the economic evidence in relation to dementia care in Ireland and addresses the issue of financing care for people with dementia at home and in long-stay care settings. Finally, dementia is explored as a public health priority, and the mobilisation of governments to act and key alliances that are making at difference at international level are discussed.
