ICC-Dementia is a dementia work group of the International Consortium of Centenarian (ICC) studies brought together to apply standard diagnostic criteria for dementia to centenarian cohorts around the world.
1. Determine the prevalence of dementia in centenarians from diverse ethnoracial and cultural groups, using common diagnostic criteria.
2. Investigate the reasons why some individuals achieve an extreme old age without showing cognitive decline.
3. Examine the biomarkers of dementia and cognitive decline in centenarians.
4. Identify the risk and protective factors, including contextual factors, for dementia and healthy brain ageing in centenarians.
