  • Alzheimer’s Disease International World Reports provide the most comprehensive picture of the impact of Alzheimer’s disease and dementia. The 2010 report discusses the economic impact of the disease, broken down by world region. The 2011 report discusses interventions and the fact that some may be more effective when started earlier. There is a strong economic argument in favour of earlier diagnosis and timely intervention. You can see the reports at http://www.alz.co.uk/worldreport.
