OBJECTIVES To examine one version of the brain reserve hypothesis in a community sample of young-old participants. The authors investigated whether atrophy and white matter hyperintensities (WMH) were associated with cognitive decline, and whether this relationship was modified by the endowment of greater "reserve" as measured by years of education and(More)
Research data on predisposition to mental health problems, and the fluctuations and regulation of emotions, thoughts, and behaviors are traditionally collected through surveys, which cannot provide a real-time insight into the emotional state of individuals or communities. Large datasets such as World Health Organization (WHO) statistics are collected less(More)
We examined whether the apolipoprotein E (APOE) ε4 allele was associated with cognitive benefits in young adulthood and whether it reversed to confer cognitive deficits in later life ("antagonistic pleiotropy") in the absence of dementia-related neuropathology. We also tested whether the ε2 allele was associated with disadvantages in early adulthood but(More)
OBJECTIVES The effect of web-based interventions for depression on suicide ideation in callers to helplines is not known. The aim of this study was to determine if web-based Cognitive Behaviour Therapy (CBT) with and without telephone support is effective in reducing suicide ideation in callers to a helpline compared with treatment as usual (TAU). A(More)
BACKGROUND Mental disorders are responsible for a high level of disability burden in students attending university. However, many universities have limited resources available to support student mental health. Technology-based interventions may be highly relevant to university populations. Previous reviews have targeted substance use and eating disorders in(More)
BACKGROUND While the evidence of an association between the apolipoprotein E (APOE) *E4 allele and Alzheimer's disease is very strong, the effect of the *E4 allele on cognitive decline in the general population is more equivocal. A cross-sectional study on the lifespan effects of the *E4 allele 1 failed to find any effect of the *E4 allele on cognitive(More)
OBJECTIVE Previous studies have shown associations between sleep disturbance and the onset of depression and anxiety. However, this relationship may reflect an underlying vulnerability, such as temperament or cognitive style, which accounts for an association between the two. This study aimed to evaluate the relationship between sleep disturbance and the(More)
BACKGROUND Mental disorders are more common in young adults than at any other life stage. Despite this, young people have low rates of seeking professional help for mental health problems. Young elite athletes have less positive attitudes toward seeking help than nonathletes and thus may be particularly unlikely to seek help. Interventions aimed at(More)
Many people at risk of suicide do not seek help before an attempt, and do not remain connected to health services following an attempt. E-health interventions are now being considered as a means to identify at-risk individuals, offer self-help through web interventions or to deliver proactive interventions in response to individuals' posts on social media.(More)
Although there is evidence of associations between anxiety, depression and cognitive function in old age, there is little work investigating relations between those variables over an extended period of time. Therefore, we used data from the Canberra Longitudinal Study to investigate 12-year cognitive change over four measurement points in relation to(More)
