This issue of International Psychogeriatrics is 96 pages thicker than usual, because it carries not only the International Psychogeriatric Association (IPA) Consensus Statement on Defining and Measuring Treatment Benefits in Dementia, but also a series of papers that were presented at the two-day conference devoted to the development of the consensus statement, which took place in the precincts of Canterbury Cathedral on 31 October and 1 November 2006. During the conference, the delegates (whose names are listed in an appendix to the consensus statement) heard presentations on what outcomes matter to people with dementia and their caregivers, how these can be measured and what they mean, cognitive change as an outcome, biological outcome measures, quality of life, neuropsychiatric symptoms (also known as behavioral and psychological symptoms of dementia (BPSD)), global measures of change, the relevance of different outcome measures to various cultures, activities of daily living, economic outcomes and the regulator perspective. These presentations have been refined into papers and are now published within these pages. In addition to 12 formal presentations on these topics, nine discussants led the conference in exploring the issues raised by the talks, and there was active and often heated debate on almost all the issues discussed. During the afternoon of 1 November agreement was achieved on several key points, which formed the basis for a draft consensus statement prepared the next day. This statement has been refined by a process of circulation among participants, whose suggestions have been incorporated into the document that is now published in this issue.
