The Coordination and Support Action (CSA) BrainHealth is preparing a European Partnership on BrainHealth to structure research and innovation in this area. The project started on November 1st, 2023 with a runtime of 24 months. Funded by the European Commission, it builds the umbrella for 21 participants from 11 countries. The CSA BrainHealth addresses policy-makers and funders from European Member States, Associated and Third Countries, and other stakeholders, in close interaction with the research community. A wide-ranging and diverse CSA BrainHealth network is created including the Funders Forum, the Stakeholders Forum, and the Scientific Advisory Board to support the development of the Strategic Research and Innovation Agenda (SRIA) in preparation for the future European partnership on BrainHealth. This European Partnership will holistically approach the biomedical, economic, and societal challenges in the field of brain health in Europe and worldwide, aiming for collaborative and innovative solutions for preservation and improvement of brain health, as well as prevention, diagnosis and therapies for neurological and mental disorders.
