The Victoria Longitudinal Study (VLS): The VLS is a long-term, large-scale, and multi-faceted investigation of human aging. The VLS examines actual changes, variations, and interactions among numerous aspects of neurocognitive aging (including memory, executive functions, speed, cognitive resources, sensory acuity) and influences on aging changes (including biological, health, genetic, lifestyle, fitness, and demographic). Incorporating epidemiological perspectives, the VLS evaluates and tracks various risk and protective factors leading to cognitive outcomes that can be characterized as normal, exceptional, impaired, or dementia. The VLS operates in two favourable locations in western Canada. The overall research, administrative, data collection, archives management, and lab headquarters of the VLS are in beautiful and booming Edmonton, the capital city of the Province of Alberta. Our dedicated longitudinal participants regularly visit our continually active VLS lab in lovely Victoria, on Vancouver Island, off the coast of the Province of British Columbia.

Leadership, Collaborators, and Support: Since its inception in the late 1980s, the VLS has been continuously funded by the U.S. National Institute on Aging, one of the National Institutes of Health (NIH). Dr. Roger A. Dixon is the long-serving VLS Director and Principal Investigator. Dr. Dixon received two consecutive terms of NIH MERIT Award funding (2002-2007; 2007-2012) for the VLS. The latest NIH grant will fund the VLS from 2013-2018 (NIH R01 AG008235; PI: R.A. Dixon). The VLS has also benefited from supplemental funding from numerous other sources, including AHFMR, Alberta Health Services, Canada Research Chairs, CIHR, NSERC, SSHRC, other NIH grants, and the Universities of Alberta (Faculty of Science, Faculty of Medicine) and Victoria (Faculty of Social Science). Both Drs. Dixon and Stuart MacDonald (VLS Co-I) gratefully acknowledge the expert contributions of several consultants. These include Drs. Kaarin Anstey (Australian National University), Lars B├Ąckman (Karolinska Institutet), Richard Camicioli (UAlberta), Ian Deary (University of Edinburgh), Scott Hofer (UVictoria), Jack McArdle (University of Southern California), and Brent Small (University of South Florida). The VLS participates in provincial networks (Campus Alberta Neuroscience), national networks (Canadian Consortium on Neurodegeneration and Aging), and international longitudinal initiatives (IALSA).

In the 2000s Roger Dixon, Stuart MacDonald, and David Hultsch met regularly in Edmonton and Victoria to plan new VLS initiatives and to work on research reports. Stuart has taken over as Co-Investigator for the
Victoria Lab. Dave retired in 2011.
