The Global Dementia Observatory (GDO) Knowledge Exchange Platform contains key resources to support the implementation of the Global action plan on the public heath response to dementia 2017-2025 and its seven action areas. The GDO KE Platform enhances countries’ and communities’ response to dementia. It provides a space for stakeholders to share resources (e.g. policies, guidelines, case studies and examples of good practice) available at no-cost, to facilitate mutual learning and promote the exchange of knowledge in the area of dementia.
