a. Introduction

Research on dementia in general and Alzheimer’s in particular takes place in many countries and with different goals. We are convinced that dementia is a global problem, which is why a solution can only be found if scientists work together globally. In order to treat an illness effectively, the underlying mechanisms must be understood in detail first.
Basic research is the basis for such knowledge. It takes place in laboratories. Based on their results, applications, innovative technologies and new approaches for the development of medicines and diagnostics arise.
Clinical research, on the other hand, examines the suitability of new diagnostics and the effectiveness of various therapies: drugs or non-drug approaches.
Health services research is interested in the effectiveness of therapies under everyday conditions and also asks how health care can be improved. For people with dementia, health services research investigates how quality of life of affected people can be improved or what support their relatives need.
