Efficient sharing of data in the experimental and clinical neurosciences would be of huge benefit to the field. Previous workshops hosted by the OECD and by INCF have identified a major obstacle to the advancement of data sharing as being the lack of incentives and support for producing, organizing and sharing reusable data. On September 21-22, INCF and OECD are hosting a workshop in Stockholm to bring together policy-makers, funders, and leading scientists to consider these issues in relation to dementia research and to begin to identify practical steps that can be taken to advance data sharing in this field.
