This section of the book focuses on research evidence from Canada, Austria and Ireland. However, the chapters in section 3 of this book are also informed by research evidence in relation to practice innovations. Research can throw light on areas that require policy support and practice developments to improve the lives of those with dementia. Research also often focuses on neglected areas of policy and practice concern, and rural dementia care has characteristically been a relatively neglected area for both rurality researchers and dementia researchers. As such this section provides a showcase for the models of care that have been developed in one area of Canada and one area of Austria that provide an evidence base to shape and inform practice developments and also to influence policy. The contribution from our Irish authors in this section demonstrates the need to collate evidence that illuminates policy and practice differences within a country and how this may lead to social exclusion and as such impacts on the lived experience of dementia. Research is a vital component of a change agenda, and the chapters in this section clearly demonstrate this.
