Our Story


The IALSA collaborative network was formally established in 2005 for the coordination of interdisciplinary, cross-national research aimed at the integrative understanding of within-person aging-related changes in cognitive and physical capabilities, health, personality, and well-being.

IALSA is comprised of investigators associated with over 45 longitudinal studies on aging, including the UK Healthy Ageing across the Life Course (HALCyon) Network and the Quebec Network for Research on Aging. These population-based and longitudinal studies permit the evaluation of how factors across the lifespan determine and moderate the risk and progression of cognitive impairment and provide a basis for early detection of neurodegenerative disorders such as dementia. These studies are currently being catalogued on the IALSA Metadata and Harmonization Platform to permit the identification of studies with comparable measures and potential for data harmonization and pooling.
