Summary
Severe depression is characterised by slowing of mental and motor abilities. Previous research by our group indicates the role of small frontal and basal brain regions in the regulation of these abilities. This research will extend our previous studies by providing new information detailing the underlying physiology of behavioural and structural abnormalities in patients with severe depression.

Previous research by our group indicates the role of small frontal and basal brain regions in the regulation of these abilities. This research will extend our previous studies by providing new information detailing the underlying physiology of behavioural and structural abnormalities in patients with severe depression. Emerging research by our group and others suggest that some types of severe depression in later life are due to undetected forms of cerebrovascular disease. If we are able to demonstrate that the key features of severe depression of this type (psychomotor, attentional, memory and executive disturbance and global disability) are related to such brain changes this may lead to a major breakthrough in the prevention and treatment of these disorders. A new type of brain imaging technology called 'functional Magnetic Resonance Imaging' (fMRI) permits simultaneous investigation of the structure and function of small areas of the brain. As the technique does not use radiation and can be performed while the patient is completing mental tasks, it can be used in repeated experiments. Consequently, it permits description of brain changes (areas of activation) that occur during specific mental tasks. Therefore, if we are now able to use this technique to extend our previous clinical and imaging studies we will be able to test whether some forms of late-life depression are due to undetected brain changes.Read moreRead less
The Cognitive Impact Of Opioids During Chronic Administration

Funding Amount
$416,024.00
Summary
Many people are now being prescribed opioid drugs for long periods of time, mainly for the treatment of chronic pain. These drugs can adversely affect the person's ability to drive a car, hold down a job, and perform normal functions of daily living. This project will investigate what types of impairment are produced by these drugs and how the drugs can best be used so as to minimise the effects on patients.
Exploring Neurological Complications In Animal Models Of Metabolic Disease

Funding Amount
$337,432.00
Summary
Diabetes causes ongoing damage to the central and peripheral nervous systems. Our research aims to understand the mechanisms of nervous system damage in diabetes by investigating changes in nervous system function overtime in animal models of pre-diabetes, type 2 diabetes and type 1 diabetes. This study specifically aims to utilize indices that can be correlated with measures obtainable in human studies and thereby achieve results with strong clinical relevance and potential for translation.
The Kids Aren’t Alright: Preventing Depression In Adolescents

Funding Amount
$600,715.00
Summary
Depression frequently emerges for the first-time during adolescence. This project examines ways to prevent depression in young people by: (i) partnering with schools to deliver broad universal programs to students through the education system, and (ii) treating sleep disturbance, a powerful but non-stigmatised risk factor for onset of depression. Findings from this research will inform innovative ways to address the depression crisis through the optimisation of prevention approaches.
Establishing The Physiological And Sleep Disruption Characteristics Of Wind Farm Versus Traffic Noise Disturbances In Sleep
Funder
National Health and Medical Research Council
Funding Amount
$1,357,652.00
Summary
Good sleep is essential for normal daytime functioning and health. Wind farm noise includes audible and unusually low frequency sound components, including infrasound, that could potentially disturb sleep through chronic sleep disruption and/or insomnia. This project will, for the first time, directly evaluate the sleep and physiological disturbance characteristics of wind farm noise compared to traffic noise reproduced in a specialised and carefully controlled laboratory environment.
Neural Circuits Which Limit Alcohol And Soft Drink Intake

Funding Amount
$523,949.00
Summary
Alcohol and soft drinks are ubiquitous, and often harmful, particularly in excess. This project will examine the specific roles of fluid and food satiation neural circuits in suppressing intake, to determine whether either or both could be therapeutic targets for alcohol/soft drink overconsumption, especially as cessation aids for binge-drinking behaviour.
What Role Do Cerebral Hypoxia And Sleep Disruption Play In The Neurocognitive Effects Of Paediatric Sleep Disordered Breathing?

Funding Amount
$558,957.00
Summary
Sleep disordered breathing (SDB) describes a spectrum of disorders caused by obstruction of the upper airway during sleep from simple primary snoring (PS) to obstructive sleep apnoea (OSA). Findings of our recently studies have provided strong evidence that all levels of SDB severity including PS are associated with neurocognitive and behavioural deficits. In this study we will investigate the mechanisms of which underpin these deficits.
Sleep-wake Disturbances And Cardio-metabolic Dysfunction In At Risk Dementia: A Novel Pathway In Neurocognitive Decline’
Funder
National Health and Medical Research Council
Funding Amount
$558,305.00
Summary
Age-related sleep and circadian disturbance and cardio-metabolic dysfunction are associated with an increased risk of dementia. This research aims to delineate the pathway in which sleep and circadian disturbances and cardio-metabolic dysfunction promote cognitive decline during the ‘at risk’ dementia phase. This will improve our understanding of key processes in cognitive ageing ultimately leading to the development of targeted intervention programs in the quest to delay the onset of dementia.
Cognitive Dysfunction In Multiple Sclerosis And Its Relationship To Mood Disturbance And Fatigue
Funder
National Health and Medical Research Council
Funding Amount
$57,342.00
Summary
This research aims to test a hypothesized model addressing the interplay between cognitive dysfunction, mood disturbance, and fatigue in people with multiple sclerosis as well as determine the associated impact on daily functioning and quality of life. The importance of background factors, disease factors and psychosocial factors in predicting cognitive dysfunction will also be investigated. Recommendations for new rehabilitation approaches will be developed in light of our findings.
