About the DEMON Network

We are the international network for the application of data science and AI to brain health research. The Deep Dementia Phenotyping (DEMON) Network brings together academics, clinicians and other partners from across the world. By connecting these people, we can identify innovative approaches to interdisciplinary collaborative dementia research across multiple institutions.

Our vision is to revolutionize brain health research by bringing innovators together and harnessing the power of data science and AI.
