Testing theoretical models of age and disease related changes to inform prevention. Pathological brain changes associated with future cognitive decline become detectable in the 40s or earlier. Yet little is known about what constitutes normal brain ageing in mid-life. Using a number of neuroimaging and epidemiological techniques this project will scrutinise brain and cognitive ageing in middle-age and their significance.
Social relations and social engagement in older adulthood: implications for health, well being and cognition. This project will examine the nature of changes in peoples social networks that occur with age and the effects of these changes on health and well being in later life. The project will use information collected as part of several ongoing Australian studies of ageing and will have implications for social policy.
Excessive sitting and population health: strengthening the science and the relevance to policy and practice. The majority of Australian adults spend most of their waking hours sitting; this increases the likelihood of developing diseases of inactivity, including diabetes, heart disease and some cancers. New research will investigate what factors encourage excessive sitting and what the health benefits are for people who deliberately do less sitting.
