Davos Alzheimer's Collaborative Healthcare System Preparedness to Increase Cognitive Assessment Rates for Older Adults

The investigators aim to perform a cluster-randomized study, exploring the effectiveness, efficiency, and acceptability of a pragmatic strategy to increase cognitive screening rates in the community. Participants will be older adults attending social and cultural centers in the greater Munich area. The investigators will compare the monetary value of different combinations of SCD questionnaires, digital cognitive tests, and blood AD biomarkers to identify the best approach for primary care settings. As secondary aims, qualitative interviews will be conducted with general practitioners (GPs) and their patients to explore the acceptability of the proposed new screening strategy; furthermore, the diagnostic utility of an artificial intelligence-based automated analysis of speech will be assessed. The initiative will not only generate novel insights into the optimal approach for large-scale cognitive screening in the general population, but also contribute to an urgently required cultural change in Germany, resulting in a sustainable solution for effective and efficient early recognition and prevention of dementia.
