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.
Dopamine-2 Receptor Antibody In Movement And Psychiatric Disorders

Summary
Autoimmune movement and psychiatric disorders are a common cause of neurological disability young adults and adolescents. We have identified a subgroup of patients whose disease is associated with an autoimmune reaction. Our study will identify the earliest immune responses against the brain in children with autoimmune movement and psychiatric disorders. Identifying these early immune responses will allow early and directed treatments to prevent disability and death in the future.
Using Genomics To Understand Psychiatric Disorders

Summary
The last five years have seen unprecedented discovery of DNA risk factors for psychiatric disorders. In my Fellowship I will combine analyses of genomic data with development of new statistical methodologies to contribute to my vision that application of genomics methods in psychiatry will continue to catalyze more discoveries of the causes of these complex genetic disorders.
Multivariate Whole Genome Estimation And Prediction Analysis Of Genomics Data Applied To Psychiatric Disorders

Funding Amount

Summary
We have made major contributions to the development of statistical methods applied to data from the international Psychiatric Genomics Consortium. Major new data sets will soon become available, with immense sample sizes (100,000s) and more extensive clinical and environmental data. We will develop and apply novel statistical analyses of these data, to answer fundamental questions about the genetic basis of psychiatric disorders and the interplay of genetic and environmental risk factors.
Epigenetic Impacts Of Paternal Experience On Offspring Anxiety And Cognition: Molecular Mediators And Therapeutic Targets

Summary
Stress and physical activity are two of the major lifestyle factors impacting on human health, including brain disorders. We have recently discovered that stress and exercise in male mice can impact the phenotype of offspring. We will study molecules in the sperm of these fathers, and in the brains of offspring to understand the mechanisms involved. There is evidence that lifestyle factors in men prior to conception impact on their children and this research has major public health implications.
Molecular And Cellular Characterisation Of Schizophrenia Associated Dysfunction In MicroRNA Biogenesis

Funding Amount
$496,205.00
Summary
We have identified substantial changes in the biogenesis of microRNA in schizophrenia. These small non-coding molecules derived from junk DNA, play a significant role in genetic regulation, with each one capable of silencing hundreds of target genes. This has major implications for schizophrenia, which is known to involve substantial changes in gene activity. The project will identify the molecular basis of this alteration in gene silencing, and its biological implications for schizophrenia.
Inflammatory Cytokines As Risk Factors For The Development Of Both Depression And Osteoporosis In Men

Funding Amount
$381,091.00
Summary
Both depression and osteoporosis impose a substantial public health burden on society and there is now research to suggest that these conditions are related. This study will examine a potential common mechanism, systemic inflammation, which may underlie both diseases. It will focus on markers of systemic inflammation, examine their association to both depression and bone fragility and determine what role they play in explaining the relationship between the disorders.
Novel Epidemiological Methods To Infer The Causal Effects Of Risk Factors On Neuropsychiatric And Cardiovascular Disorders

Funding Amount
$182,003.00
Summary
Epidemiological studies, which associate risk factors and disease, are central in informing public health policy. Because causality is difficult to ascertain from these associations, public health interventions based on these findings are at some risk of failure. We propose to develop, extend and apply an innovative epidemiological approach, Mendelian randomization (MR) to resolve the causal relationship between risk factors and neuropsychiatric and cardiovascular disorders.
Intergenerational Impacts Of Paternal Immune Activation On Brain Function And Dysfunction

Funding Amount
$997,690.00
Summary
We recently discovered that infection of male mice with a parasite (Toxoplasma gondii) before conception can change the epigenetic information in the sperm and alter behaviour of the offspring. This is the first evidence that pathogenic infection in males can affect the next generation. We will investigate how infection with other major pathogens, including bacteria and the virus causing COVID-19, may affect sperm epigenetics and offspring health, including their brain function and dysfunction.
