Summary
Schizophrenia is a severe psychiatric disorder that affects approximately 1% of the population. This project will help define changes in the molecules in the brain of subjects with schizophrenia which are likely to be involved in two symptoms of the disorder, the psychoses and cognitive deficits. Understanding the cause of the cognitive deficits of schizophrenia is a high priority because they are the most disabilitating symptom of the disorder and do not respond to current drug treatments.
Schizophrenia is classified among the world’s top ten enduring disabilities. Hearing voices are a profound and distressing symptom, which have proven difficult to successfully treat. We plan to use the latest brain imaging techniques and genetic testing to develop the most comprehensive understanding of hearing for voices to date. These data are vital to the development of novel tailored treatment for patients who hear voices.
Antipsychotic Medication In First-episode Psychosis: An RCT To Assess The Risk-benefit Ratio

Summary
There has been an increasing emphasis on intervening early in psychotic disorders. A fundamental principle in early intervention is “to do no harm” and benefits must outweigh the risks of treatment. While antipsychotic medication is very effective and evidence-based form of treatment for positive symptoms in most first episode psychosis (FEP) patients it has risks. This study has the potential to determine whether antipsychotic medication should be the initial treatment option for FEP.

Summary
This area of research is concerned with improving our ability to identify young help-seeking patients who are most at risk of developing psychotic disorders and provide intervention to delay or prevent the onset of psychosis. A number of studies are planned, including researching disturbances in sense of self, neurocognitive factors, history of trauma and reaction to stress as predictive of future onset of psychosis, as well as a study of omega-3 fatty acids (fish oil) as an intervention for the ....This area of research is concerned with improving our ability to identify young help-seeking patients who are most at risk of developing psychotic disorders and provide intervention to delay or prevent the onset of psychosis.

Thalamocortical Neural Circuits In Higher Order Cognitive And Sensory Processing

Summary
Schizophrenia, depression and dementia are devastating disorders with problems in thinking and sensory perception, but the neural circuits causing these symptoms are not known. I will use new optical and genetic tools in mice to identify the cortical and subcortical circuits required for complex touchscreen tasks, the same tasks to assess patients. Identification of neural circuits that underlie clinical symptoms will increase our understanding of these disorders and improve treatments.
The Efficacy Of N-acetyl Cysteine As An Adjunctive Treatment For First Episode Psychosis

Funding Amount
$2,143,069.00
Summary
First episode psychosis may foreshadow devastating, chronic illness. Psychosis follows a staged, progressive pathway. There is evidence to suggest illness progression can be diminished and perhaps even averted if appropriate treatments are given at the early stages of illness. This project will test if N-acetycysteine (NAC) administered to young people who have experienced a first episode of psychosis can help prevent this early psychotic experience from developing into a chronic disorder.
Improving Physical Health Outcomes For Young People With Psychotic Disorders

Funding Amount
$189,384.00
Summary
Enduring psychotic disorders are associated with a reduced life expectancy by 25 years, which is mainly due to cardiovascular disease. This project will produce a training package that will improve clinician’s skills and knowledge of screening and treatment for physical health risk factors in young people with psychosis. This project will result in the development of an intervention for reducing the prevalence of these cardiovascular risk factors known to contribute to this early mortality.
From Brain Maps To Mechanisms: Modeling The Pathophysiology Of Schizophrenia

Funding Amount
$320,891.00
Summary
My Fellowship will develop a framework that integrates brain imaging data with mathematical models of the brain to help understand the mechanisms responsible for schizophrenia. By linking functional Magnetic Resonance Imaging (fMRI) measurements to models of their underlying causes, the work may lead to new treatments that target the specific dysfunction in individuals with this debilitating brain disorder.
A Dimensional Approach To Mapping The Risk Mechanisms Of Mental Illness

Funding Amount
$1,677,975.00
Summary
There is ongoing debate about whether current definitions of mental disorders are accurate. We will use statistical techniques to identify the core dimensions of liability for mental illness, and map how genes and brain organization drive differences between people along each dimension.
Mechanisms Guiding Pathfinding And Positioning Of Cortical Interneurons

Summary
Brain disorders place an economic and social burden on Australia and the personal costs of these illnesses are immeasurable. Several brain abnormalities are caused from the failure of neurons to position themselves in the correct location when the brain develops. Our study aims to discover how neurons move and what factors influence this process. It provides an understanding of normal brain development, as well as providing insight into what may go wrong in the formation of brain diseases.
