OBJECTIVES Few studies report incidence of mild cognitive impairment (MCI) and other mild cognitive disorders (MCD) in cohorts in their 60s, at an age when diagnoses are less stable. The authors' goal was to estimate the incidence and prevalence of MCI and MCD, characterize subgroups with stable vs nonstable diagnoses, and evaluate the impact of diagnosis(More)
OBJECTIVE The authors report the population prevalence of depression in older adults living in the community and in residential care. Demographic, medical, health behavior, functional and cognitive measures, and transition to residential care are evaluated as risk factors for depression over eight years. METHODS Depression prevalence estimates were(More)
OBJECTIVE To investigate whether subjective memory decline (SMD) in cognitively healthy individuals is associated with hippocampal atrophy. METHODS Multiple regression analyses assessing the relationship between hippocampal atrophy over 4 years and SMD at baseline and follow-up in 305 cognitively healthy individuals aged 60-64 years free from dementia,(More)
BACKGROUND Self-rated health is commonly employed in research studies that seek to assess the health status of older individuals. Perceptions of health are, however, influenced by individual and societal level factors that may differ within and between countries. This study investigates levels of self-rated health (SRH) and correlates of SRH among older(More)
We investigated the association between glucose tolerance status and trajectories of change in blood glucose, and cognitive function in adults aged 25 to 85. The sample (n = 4547) was drawn from a national, population-based cohort study in Australia (AusDiab). Fasting plasma glucose (FPG), glycated haemoglobin (HbA1c) and general health were assessed at 0,(More)
OBJECTIVE We describe population-level cognitive development in early middle-age and evaluate whether cardiovascular risk factors for late-onset dementia influence cognitive change in midlife. METHOD The sample from the PATH Through Life (PATH) Project (N = 2,530; 40-44 years of age at baseline) was drawn randomly from the community, followed for 8 years,(More)
Negative self-perceptions of aging (SPA) have been linked to poor physical health and functioning outcomes in late life, yet the direction of this relationship remain unclear. Using data from the Australian Longitudinal Study of Aging, we investigated the directionality of the dynamic relationship between self-perceptions of aging and physical functioning(More)
This study examined the effect of age-stereotype threat on older adults' performance on a task measuring hazard perception performance in driving. The impact of age-stereotype threat in relation to the value participants placed on driving and pre- and post-task confidence in driving ability was also investigated. Eighty-six adults aged from 65 years of age(More)
OBJECTIVE This study investigated the effect of the reference point of self-rated health (SRH) items on the trajectory of older adults' subjective health. DESIGN Seven waves of data from the Australian Longitudinal Study of Ageing (1992 to 2004) were used to determine change in SRH in a large sample (N = 2,081; 49% men) of older adults (65+ years). MAIN(More)
BACKGROUND Self-rated health (SRH) measures with different wording and reference points are often used as equivalent health indicators in public health surveys estimating health outcomes such as healthy life expectancies and mortality for older adults. Whilst the robust relationship between SRH and mortality is well established, it is not known how(More)
