Funding Amount
$531,496.00
Summary
Transcranial magnetic stimulation (TMS) has been touted as a viable treatment for a range of psychiatric and neurological disorders. However, the extent to which localised TMS influences widespread brain networks remains unknown. To fill this gap, we will combine neuroimaging and TMS in healthy adults. The project will provide a scientific foundation for the use of brain stimulation as an effective tool for improving function in a range of clinical conditions.
A New Animal Model Of The Prodrome In Schizophrenia. Enhanced Dopamine In Prodromal Schizophrenia (EDiPs)

$571,990.00
Summary
Psychiatrists now recognize a pre-symptomatic stage is present in people at risk of developing schizophrenia. Using new brain imaging techniques we now know that some of these individuals have changes in a major neurotransmitter, dopamine, prior to being diagnosed. We have developed a new model in animals, which recreates these exact same changes at a comparable age. We want to now understand what are the broader effects in the brain and try and block these changes in dopamine with new drugs.
Resilient Brain Networks In Patients With Schizophrenia And Their Unaffected Siblings

Funding Amount
$474,226.00
Summary
An individual’s risk for schizophrenia is usually evaluated in terms of their familial, environmental and neurobiological risk factors. Our research indicates that factors conferring resilience to becoming ill are just as important. This study will use brain imaging techniques to study individuals with schizophrenia and their unaffected siblings, aiming to identify factors that have provided the unaffected siblings with resilience to becoming ill, despite their familial risk.
Selective Serotonin Re-uptake Inhibitors (SSRIs) And Osteoporosis: Mechanisms And Clinical Consequences

$422,964.00
Summary
Selective serotonin re-uptake inhibitors (SSRIs) are commonly used to treat depression. Serotonin is not unique to the brain but is also used by other cells in the body, including bone cells. In this project the influence of SSRIs on human osteoclast and osteoblast formation and function will be investigated in a laboratory. Additionally, the impact of SSRI use on bone loss and fracture risk in a community sample of women and men will be investigated. These studies will determine if exposure to ....Selective serotonin re-uptake inhibitors (SSRIs) are commonly used to treat depression.

Preconception Determinants Of Child Health And Development: A 4-year Follow Up Of Offspring Born To The Australian Temperament Project
Funder
National Health and Medical Research Council
Funding Amount
$1,065,799.00
Summary
This project will follow offspring born to a large population cohort study that has tracked the mental health and wellbeing of around 2000 participants across 30 years prior to parenthood. The aim is to understand how the lives parents lived before conception, as well as events during pregnancy, shape social and emotional outcomes for their children. Results will inform radically new approaches to promoting child health and development across generations.
The Transmission Of Perinatal Maternal Mental Health To Preschool Emotional Disorders: Examining Pathways And Intervention Points In The MPEWS Study
Funder
National Health and Medical Research Council
Funding Amount
$970,795.00
Summary
While it is known that depression, anxiety and stress in pregnancy increase the risk for poorer child mental health, what is unknown is the key pathways and intervention points to prevent this transmission of risk. This study will examine potential mechanisms and intervention points through a selected cohort study: Mercy Pregnancy and Emotional Wellbeing Study. This study follows 500 women and their children from first trimester in pregnancy until the children are 3 years of age.
Adjunctive Hormone Therapy For Treatment Resistant Depression In Perimenopausal Women

Funding Amount
$620,946.00
Summary
Women entering the menopause have increased rates of treatment resistant depression with poor response to standard antidepressant treatment. We propose to conduct a clinical trial of a novel adjunctive hormone, tibolone, to improve the outcomes for middle – aged women with severe depression.
Maternal Vitamin D Supplementation In A Maternal Immune Activation Model Of Schizophrenia: Mechanisms Of Prevention
Funder
National Health and Medical Research Council
Funding Amount
$523,364.00
Summary
Maternal infection and vitamin D deficiency during pregnancy increase the risk of children developing schizophrenia. We model these risk factors in pregnant mice. Offspring produce schizophrenia-like behaviours. When pregnant mice with experimental inflammation are treated with the hormonally active form of vitamin D this completely abolished all schizophrenia-like behaviours in offspring. We want to a) understand this mechanism, b) replicate using a form of vitamin D safe-to-use in humans.
Expanding The Power Of Genetic Analysis Of Complex Traits In Multiply Phenotyped Twin Sibships

Summary
Our aim is to identify genes influencing common diseases including melanoma, asthma and cardiovascular disease. We measure adolescent twins for moliness, skin, hair and eye colour and a variety of blood traits. We have already found new genes for mole count, eye colour, skin damage, and several different blood cell types. For each of these disease traits there are many more genes to be found and these will inform new treatments. We plan to genotype 600 new families (2000 individuals) to help ach ....Our aim is to identify genes influencing common diseases including melanoma, asthma and cardiovascular disease.

A Randomised Controlled Trial Of NMDA Antagonist, Memantine, For The Treatment Of Borderline Personality Disorder

Funding Amount
$993,067.00
Summary
Borderline Personality Disorder (BPD) affects 5.9% of Australians and is a poorly understood mental illness with no clear medication treatment. The key symptoms of BPD all stem from impaired cognitive processes. Our early data shows improvement of symptoms with memantine - a cognitive enhancing drug used in Alzheimer’s disease.We plan to conduct a clinical trial; giving either 20mg memantine or placebo to 150 people with BPD across 2 Victorian sites.
