"Researchers of brain ageing from around the world come together in the COSMIC (Cohort Studies of Memory in an International Consortium) collaboration to determine what factors are common for cognitive decline and dementia in all human populations irrespective of race, ethnicity and socioeconomic development.
COSMIC has so far brought together 47 cohort studies of cognitive ageing from 35 countries across 6 continents, with a combined sample size of almost 150,000 individuals. The aim of the collaboration is to facilitate a better understanding of the determinants of cognitive ageing and neurocognitive disorders. This is being achieved by:
1. Harmonising shared, non-identifiable data from cohort studies that longitudinally examine change in cognitive function and the development of dementia in older individuals (60+ years).
2. Performing joint or mega-analyses using combined, harmonised data sets that yield collated results with enhanced statistical power, in addition to comparisons across diverse ethno-regional groups."
