The G8 Health Ministers met at the G8 Dementia Summit in London on 11 December 2013 to discuss how to shape an effective international response to dementia. They note the socio-economic impact of dementia globally, and therefore call for greater innovation to improve the quality of life for people with dementia and their carers, while reducing emotional and financial burden. They acknowledge the need to develop a co-ordinated international research action plan and for high-level fora in partnership with the OECD, WHO, the EU Joint Programme on Neurodegenerative Disease (JPND), and civil society. This declaration is signed by the G8 Health and Science Ministers (from the UK, Canada, France, Germany, Italy, Japan, Russia and the United States). They will meet again in the United States in February 2015 with other global experts, including WHO and OECD, to review the progress that has been made on their research agenda.
