Summary
Currently, mood disorders are classified by severity, largely ignoring causes and leading to limited treatments. The Team will clarify how differing depressive and bipolar (mood) disorders are best modelled and pursue their differing causes, so assisting identification of specific treatments relating to their underlying causes. Our studies employ a range of sophisticated technologies, including molecular biology, brain imaging techniques, and mathematical modeling.

The Team will clarify how differing depressive and bipolar (mood) disorders are best modelled and pursue their differing causes, so assisting identification of specific treatments relating to their underlying causes. Our studies employ a range of sophisticated technologies, including molecular biology, brain imaging techniques, and mathematical modeling. The capacity of such research to advance the management of mood disorders address a pressing clinical need.Read moreRead less
A Prospective Study Of Inflammatory Cytokines As Common Factors In The Aetiology Of Both Depression And Osteoporosis.

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.
Understanding The Role Of Muscarinic Receptors In The Pathophysiology Of Depression And Bipolar Disorder

Summary
The causes of bipolar disorder and major depressive disorder, which effect many Australians, remain unknown. We have recently shown decreases in muscarinic receptors in the brain of people with bipolar disorder and major depressive disorder. Muscarinic receptors are important in maintaining the functions of the brain that seem to be affected in people with bipolar disorder and major depressive disorder. Here we seek to understand how changes in muscarinic receptors occur in both disorders.
Australasian Partnership For Improving Outcomes In Severe Depression

Funding Amount
$909,752.00
Summary
This 5-year project examines how proven treatments are used in real-world clinical practice, and how this can be improved. The project focuses on important physical interventions for depression: Electroconvulsive therapy (ECT), Ketamine, repetitive Transcranial Magnetic Stimulation (rTMS), transcranial Direct Current Stimulation (tDCS). The use of ECT to treat schizophrenia will also be examined. The research team will partner with clinical service providers and a government health department.
Rumination And Deficits In The Recall Of Positive Autobiographical Memories In Depression

Funding Amount
$263,295.00
Summary
The prevalence of depression is increasing and risk of recurrence exceeds 80%. The social and economic burden of depression highlight the urgent need to advance understanding of the habits of thought and memory that keep people feeling depressed, so that psychologists can treat depression more effectively. This project will explain why depressed people feel worse when they recall happy memories. The outcomes will extend theory and guide the improvement of treatments for this condition.
THE NEUROBIOLOGICAL BASIS OF INDIVIDUAL DIFFERENCES IN SUSCEPTIBILITY TO THE CONSEQUENCES OF STRESS

Summary
Stress plays a major role in the development and progression of many different mental health disorders. However, as we all know, the effects of stress on one person can be very different from its effects upon another. This is at least partly explained by differences in individual coping styles. When faced with a stressful situation without a ready solution, people tend to divide into two broad camps: those with an innate tendency to adopt passive coping strategies, such as avoidance, and those t ....Stress plays a major role in the development and progression of many different mental health disorders. However, as we all know, the effects of stress on one person can be very different from its effects upon another. This is at least partly explained by differences in individual coping styles. When faced with a stressful situation without a ready solution, people tend to divide into two broad camps: those with an innate tendency to adopt passive coping strategies, such as avoidance, and those that tend towards active coping strategies, such as attempting to take control of the situation. Previous studies have provided findings that suggest that passive coping is more common amongst sufferers of depression, post-traumatic stress disorder, and chronic pain syndrome than is active coping. But is this cause, or effect? And what are the intervening brain mechanisms? We attempt to address such questions in the present project using an animal model in which social conflict has been shown to trigger depression-like symptoms. In particular we wish to: (i) determine whether the patterns of brain activity triggered by social conflict are different for active vs. passive copers; (ii) determine whether the depression-like consequences of social conflict are more severe in passive than in active copers; (iii) determine whether differences in coping style and vulnerability to social conflict stress are due to the actions of a particular neurotransmitter, dopamine, in the prefrontal cortex of the brain; (iv) determine whether the actions of antidepressants might be attributable changes in prefrontal cortex dopamine function which in turn promote active coping in preference to passive coping. These studies will provide exciting new information about the neurobiological basis of individual differences in vulnerability to the harmful effects of stress, and thus will offer the hope of developing new ways of preventing devastating illnesses such as depression.Read moreRead less
Self-help For Depressive Symptoms: Finding Messages Suitable For Population-wide Promotion

Summary
Members of the community often use self-help methods to reduce symptoms of depression. In some cases, these may be effective, but in others they may do more harm than good (e.g. self-medication with nicotine or alcohol). The project aims to find out which self-help methods are most likely to be helpful and are easy for the community to use. These methods can then be promoted in educational campaigns to improve how people cope with symptoms of depression.

In some cases, these may be effective, but in others they may do more harm than good (e.g. self-medication with nicotine or alcohol). The project aims to find out which self-help methods are most likely to be helpful and are easy for the community to use. These methods can then be promoted in educational campaigns to improve how people cope with symptoms of depression. If people can take action to reduce milder levels of depression, this may prevent them from progressing to develop a clinical disorder that needs professional treatment.Read moreRead less

Summary
rTMS is a new treatment for depression progressively being utilized in clinical practice. However, response to rTMS treatment is usually slow with treatment courses taking over 4-6 weeks. In the current study we will evaluate the efficacy of an accelerated from of rTMS administration: a course of intensive treatment being applied over a 3 day period.
A New Target For Antidepressant Treatment: Microglia Mediated Neuroinflammation

Summary
Depression is the leading cause of non-fatal disease burden in Australia. Unfortunately, current antidepressants do not provide adequate levels of relief and it is accepted that we need to develop more effective treatments. We have recently shown that a drug that reduces inflammation in the brain also reduces depression-like symptoms. This project aims to extend upon these extremely promising findings, in the hope of developing a new and more effective generation of antidepressants.
