During the last few years, dementia prevention based on modifiable lifestyle factors has gained increasing attention. Cohort studies with follow-ups extending up to decades have identified several risk and protective factors, and very recently new randomized controlled trials with multidomain approach have provided promising evidence by showing that modifying simultaneously several risk factors, it is possible to maintain and improve cognitive capacity among older at-risk persons. Several lifestyle-based multidomain trials are under preparation or ongoing and to facilitate international collaboration and effective worldwide dementia prevention, the World Wide FINGERS interdisciplinary network (http://wwfingers.com) was recently initiated. Additionally, several new implementation projects are taking the first steps from trial setting to real-life implementation of a dementia prevention program. This paper highlights the recent perspectives from the field of Alzheimer's disease and reflects the implications and importance of current achievements. Finally, predictions for the future work especially in terms of global collaboration and implementation will be discussed.
