Suzanne Tyas

Dr. Suzanne Tyas (she/her) is a neuroepidemiologist whose research program aims to identify strategies to help preserve cognition in older adults. To do so, her research identifies factors across the life course that put people at risk of developing Alzheimer’s disease, as well as factors that build cognitive reserve and increase the chance of healthy aging. These factors span early-life to late-life factors and include social factors such as social support and social isolation; mental health factors such as depression and loneliness; linguistic factors such as multilingualism and writing skills; intellectual factors such as education and school grades; and vascular factors such as diabetes and migraine.

Dr. Tyas' research uses longitudinal studies of aging and cognition, including the Canadian Longitudinal Study on Aging, the Nun Study, the Kuakini Honolulu-Asia Aging Study, the Manitoba Study of Health and Aging, the Canadian Study of Health and Aging, and SMART, a data harmonization project spanning 11 major North American clinico-pathologic studies of dementia.
