According to estimates of the World Health Organization, the number of people living with dementia will double almost every 20 years for the foreseeable future. While in 2010, there were 35.6 million people with dementia worldwide, this number is expected to increase to 65.7 million by 2030, and to 115.4 million by 2050. The primary aim of this book Dementia Care: International Perspectives is to present arrangements for the care of people with dementia and their families in different parts of the world and to serve as a stimulus to develop new ideas for the provision of such care. While preparing this book, we asked the world’s leading experts in the field of dementia five questions—having initially gathered information about these issues through an Internet search. The results of this enquiry are shown for 45 of the countries, and the summary is presented. We have attempted to include, as far as we can, within the constraints of publishing a volume which is manageable and digestible for the reader, the descriptions of care for people with dementia in 47 countries, hoping that these descriptions will reflect the wide spread of countries, big and small, geographically diverse from all continents, and encompassing the major language and culture groups.
