Summary
Depression is a substantial clinical problem for which ECT is the most efficacious treatment. However, ECT has cognitive side-effects which limit its applicability and acceptance by patients. The development of a new treatment with similar efficacy but which minimizes these side effects would have great clinical value. One promising possibility is magnetic seizure therapy (MST). This project will investigate the neurological outcomes of MST in depression, focusing on the cognitive outcomes.

Summary
Epilepsy is one of the most common neurological disorders, affecting 1-2% of the population. Many epilepsy patients do not respond to drug therapy and their only hope for seizure control is surgical removal of the part of the brain responsible for their seizures. Successful surgery is very much dependent on the ability to exactly localize the seizure focus and this is often not possible using the imaging techniques currently available.

Many epilepsy patients do not respond to drug therapy and their only hope for seizure control is surgical removal of the part of the brain responsible for their seizures. Successful surgery is very much dependent on the ability to exactly localize the seizure focus and this is often not possible using the imaging techniques currently available. Functional magnetic resonance imaging (fMRI) is a new technique which may improve our ability to localize the seizure focus from which seizures arise, if the brain can be imaged at, or near, the time of a seizure. MR spectroscopy (MRS) enables us to detect metabolic changes in the brain which may persist at the site where seizures have begun for up to 30 minutes after the seizure. The aim of our research is to obtain a greater understanding of the changes detected with these MR modalities so that we can learn to apply these techniques to human sufferers of epilepsy. Ultimately it may help enable previously incurable epilepsy patients to undergo successful surgery and live normal lives.Read moreRead less
Neourobiology Of Human Epilepsy: Genes, Cellular Mechanisms,network And Whole Brain

Funding Amount
$17,652,824.00
Summary
The team is comprised of neurologists, molecular geneticists, physiologists and brain imaging specialists and leads the world in the discovery of the genetic causes of epilepsy. They will continue to identify genes underlying epilepsy and study how genetic variations result in development of seizures. Advanced brain imaging will be used to understand the effects of genetic variation on brain structure and function. This study may lead to new diagnostic methods and treatments for epilepsy.
Refining Treatment Strategies For Youth Depression: Clinical Trials And Biomarker Development

Funding Amount
$339,221.00
Summary
Depression is the biggest contributor to disease burden of all illnesses suffered by young people. Despite this existing treatments are often not effective. The Career Development Fellowship will aid efforts to improve treatments for youth depression, by enabling the implementation of important clinical trials, and the identification and development of imaging biomarkers that can help to target treatments at patients most likely to benefit from them.
A Randomised Controlled Trial Of Low-dose Ketamine In Youth With Severe Depression And Elevated Suicide Risk
Funder

Funding Amount
$2,232,757.00
Summary
Recent research has shown that a single injection of low-dose ketamine has powerful, though short-lived, antidepressant effects. Effective treatments are urgently needed for young people with severe depression. This will be the first controlled study to test whether repeated doses of ketamine, given over 4 weeks, is effective for young patients.
Strengthening Functional Connectivity In The Ageing Brain.

Funding Amount
$320,891.00
Summary
Age-related deficits in the ability to perform meaningful, voluntary movements markedly increase the likelihood of experiencing falls, a major cause of injury among older adults. Using advanced neurophysiological techniques, this project will (1) define the role of functional connectivity decline in age-related movement deficits and (2) gain a mechanistic understanding of improvements in voluntary movement control through a promising intervention for reversing age-related functional decline.
Role Of Neurogenesis In Clinical Recovery From Depression During ECT: Application Of A Novel In Vivo Magnetic Resonance Spectroscopy Technology

Funding Amount
$587,478.00
Summary
Neurogenesis refers to the generation of new brain cells, which is now known to continue well into adulthood. On the basis of animal studies, deficiencies in neurogenesis have been implicated in development of depression, and stimulation of neurogenesis proposed as one of the ways that anti-depressants may work. Using the latest technological advances in brain imaging, we will for the first time assess the merit of these theories in humans with depression before and after treatment.
Neural Predictors Of Treatment Response In Youth Depression

Funding Amount
$519,596.00
Summary
Depression is the single greatest cause of disability and morbidity in young people. In order to reduce its substantial burden on individuals and society, there is a need to optimise the early provision of existing treatments. In this study, we will use cutting-edge neuroimaging technology to identify “biomarkers” in the brain that will help to more accurately determine which available treatments are likely to be most effective and safe for an individual patient.
Controlling Intrusive Images In Psychopathologies: Disarming Symptoms And Enhancing Treatment

Funding Amount
$285,085.00
Summary
This proposal will conduct the first pre-clinical study disarming symptoms and enhancing treatment of many psychopathologies by controlling the strength of mental imagery. This study represents the first attempt to alleviate symptoms by developing a cognitive-neuroscience vaccine to control the strength of traumatic imagery and to show a causative means of enhancing imagery strength to boost the success rate of cognitive therapy involving imagery.
