Imaging is increasingly being used by clinicians to enhance accuracy of diagnosis and to give important information regarding co-morbid pathologies which have an impact on management and prognosis. Imaging changes are increasingly entering clinical diagnostic criteria, and consensus clinical criteria for all main subtypes of dementia now include information about imaging changes. In addition, many clinical guidelines for dementia emphasize the need for informed, appropriate application of different imaging modalities in varying clinical situations.

The Scientific Committee and Congress Organizing Committee of the 2015 IPA International Congress would like to thank everyone who has contributed to the Scientific Program. Together we have produced a rich and diverse program, reflecting IPA's mission, which upholds its high standards of scientific quality. Appreciation is also extended to all members of the Scientific Committee for their dedication and hard work in helping to develop the program and assess all the abstracts prior to acceptance.

Abstracts for oral and poster presentations from the 2015 IPA International Congress included in this supplement have been assessed by the Scientific Committee. They have not been peer-reviewed under the supervision of the Editor-in-Chief of International Psychogeriatrics prior to publication, but may still be cited.
