Summary
Adult anxiety and depressive disorders are common, cause significant distress to sufferers and cost to the community, and generally begin in childhood. Prior research has shown that children who exhibit higher than average levels of anxiety in their late childhood are at risk for developing anxiety and depressive disorders as they grow older. However if at risk children can learn skills to better manage their anxiety, the chance that they will continue to experience significant anxiety problems ....Adult anxiety and depressive disorders are common, cause significant distress to sufferers and cost to the community, and generally begin in childhood. Prior research has shown that children who exhibit higher than average levels of anxiety in their late childhood are at risk for developing anxiety and depressive disorders as they grow older. However if at risk children can learn skills to better manage their anxiety, the chance that they will continue to experience significant anxiety problems is greatly reduced. For example, school-based skills-building programs run by specialist mental health professionals have been shown to reduce the rate of existing anxiety disorder and prevent the onset of new anxiety disorders across middle to late childhood and early adolescence. The proposed study will aim to show that a school-based program, run by school counsellors, can prevent the development of anxiety and depressive disorders in late adolescence. In other words, the aim is to demonstrate whether the benefit of the program can be achieved across the wider school-aged population when conducted wholly within the education sector. This outcome is significant, not only in its potential to reduce distress to a large number of adolescents and their families, but in reducing costs to the community in terms of reduced disability and reduced need for health care and specialist mental health treatment.Read moreRead less
Providing Evidence For The Primary Prevention Of The High-prevalence Mental Disorders In Men: The Role Of Diet In The Aetiology Of Depression, Anxiety, And Psychological Distress

Funding Amount

Summary
Depression is predicted to become the second-most common cause of disability in the world by 2020, despite the increased energy devoted to recognition and treatment. This study will examine the association between diet quality and depressive and anxiety disorders in men, to identify to what extent diet quality is related to the risk for and/or course of these illnesses.
Structural And Functional Studies On Glutamate Decarboxylase.

This proposal aims to determine the molecular structure of the two known isoforms of Glutamate Decarboxylase (GAD65 and GAD67). GAD in an essential human enzyme that is responsible for synthesising the primary inhibitory neurotransmitter gamma-aminobutyric acid (GABA).

GAD in an essential human enzyme that is responsible for synthesising the primary inhibitory neurotransmitter gamma-aminobutyric acid (GABA). GABA functions in the human Central Nervous System (CNS) to dampen down excitatory signals. Proper control of GABA synthesis is important and perturbations in GABA levels lies behind human diseases such as intractable epilepsy, depression and schizophrenia. As a result of this role, numerous common therapeutics (for example benzodiazepines) target proteins involved in the GABA neurotransmitter system. The goal of this proposal is to use the molecular structures of GAD to understand how to achieve fine control of GABA production. In addition to its role in the CNS, GAD is an important human autoantigen. Antibodies to one isoform of GAD, GAD65, are found in most patients with type I diabetes as well as certain patients with the movement disorder stiff person syndrome and related diseases of the CNS. It is suggested that the development of auto-antibodies may play a key role in the pathophysiology of these conditions. Despite sharing >80% sequence similarity with GAD65, autoantibodies to the other isoform of GAD, GAD67, are rarely found in patients with disease. The aim of this grant is to characterise the region of GAD that is targetted by autoantibodes. These data will allow us to understand why certain autoantibodes are able to inhibit GAD enzyme activity and why GAD65, but not GAD67 is recognised by autoantibodes.Read moreRead less
Transdiagnostic Internet Therapy For Internalizing Disorders

Funding Amount

Summary
Anxiety and depressive disorders account for 58% of the burden of mental disorders, or 7.5% of the burden of human disease. Internet treatments for the individual disorders are effective but require careful diagnosis. We intend to develop and prove the effectiveness of a transdiagnostic Internet treatment program that will be easily used by primary care clinicians. We will disseminate and evaluate the developed and proven program to general practitioners and psychologists.
Improving Internet-delivered Psychological Therapies For Depression And Anxiety

Summary
Depression and anxiety affect 3 million Australians. While effective psychological treatments exist, even the best only help 50% recover, and relapse is common. My research aims to improve the treatment of adult depression and anxiety, through developing more effective, efficient and accessible internet-delivered psychological therapies and identifying the conditions that promote optimal long-term outcomes.
A Prospective Study Of Inflammatory Cytokines As Common Factors In The Aetiology Of Both Depression And Osteoporosis.
Funder
National Health and Medical Research Council
Funding Amount
$291,230.00
Summary
Both depression and osteoporosis are common, debilitating and expensive diseases and there is research to suggest that these conditions are related. This study will examine a potential common mechanism, inflammation, which may underlie both diseases. It will focus on circulating proteins which are associated with both depression and fragility fractures, and examine the role they play in both disorders.
Depression Prevalence: Delineation Issues In 2007 National Mental Health & Wellbeing And 2008 South Australian Surveys

Funding Amount
$257,051.00
Summary
It is believed depression is increasing and Australia has many health interventions to help, but it is unknown if these are reducing depression prevalence. Two surveys have reported on depression in the past 10 years. One shows it is decreasing, the other it is increasing. This study will examine depression measurement in both surveys to find out why they disagree. The findings will have implications for future depression measurement and what health care interventions should be planned.
Randomised Trial Of Homocysteine Lowering Treatment Of Depression In Later Life (B-VITAge)

Funding Amount
$775,530.00
Summary
The causes of depression in later life are varied and complex, but available evidence suggests that cardiovascular disease plays an important role. High homocysteine (a robust risk factor for myocardial infarction and strokes) accounts for about 20% of all cases of depression in older age. We have previously shown that treatment with vitamins B12, B6 and folate reduces homocysteine. We propose to run a trial to test if lowering homocysteine decreases the severity and prevalence of depression.
Adaptive Screening For Depression, Anxiety And Suicidality For Online Interventions And Primary Care

Funding Amount
$307,946.00
Summary
A large proportion of people with depression, anxiety or suicidality do not seek help. Existing methods to screen for these conditions are not sufficiently effective and are not well incorporated into health care systems. This study will develop new, individually tailored ways to screen for mental health conditions. The study will test the implementation of these screening tools into a tailored service that combines online and primary care services.
