Our Story


The Integrative Analysis of Longitudinal Studies of Aging and Dementia (IALSA) research network was formally established in 2005 to facilitate interdisciplinary, cross-national research on determinants and dynamics of within-person aging-related changes in cognitive and physical capabilities, health, personality, and well-being. The network is comprised of investigators associated with over 125 longitudinal studies on aging and dementia. A key feature of the IALSA network is the optimization and evaluation of the reproducibility of results from longitudinal and life course studies, achieved through a coordinated analysis approach based on comparable statistical models and measurements. Network activities encourage the examination of cross-cultural and cross-cohort effects and synthesis of results across longitudinal studies.

IALSA activities are currently funded by NIH/NIA grants 1R01AG067621 (PI: Hofer, OHSU, 2019-2024) and 1R01AG067622 (PI: Mroczek, Northwestern, 2019-2024) and previously funded by NIH/NIA grants P01AG043362 (PI: Hofer, Co-PIs: Kaye, Muniz-Terrera, Piccinin, OHSU, 2013-2019), R01AG026453 (PI: Hofer, UVic, 2007-2013) and CIHR 103284 (PI: Hofer, UVic, 2010-2013).
