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.
A Prospective Cohort Study Of Mortality, Abstinence, Criminality And Psychiatric Comorbidity

Summary
Over 70 000 Australians are dependent on heroin. Heroin dependence is remarkably persistent and is, in many cases, a lifelong condition. Long term treatment outcome and abstinence from heroin among this group are poor. Mortality among heroin users is high, with heroin users dying at a rate 13 times that of peers. Despite the extent of the problem, the natural history of heroin users has not yet been studied in Australia. The current study will be the first Australian study of the natural history ....Over 70 000 Australians are dependent on heroin. Heroin dependence is remarkably persistent and is, in many cases, a lifelong condition. Long term treatment outcome and abstinence from heroin among this group are poor. Mortality among heroin users is high, with heroin users dying at a rate 13 times that of peers. Despite the extent of the problem, the natural history of heroin users has not yet been studied in Australia. The current study will be the first Australian study of the natural history of heroin users. The study will follow up a large cohort of heroin users over a three year period. Estimates will be obtained of mortality rates, abstinence rates, criminal careers, and psychiatric problems among heroin users. It will also examine factors that predict abstinence, mortality, criminality and levels of psychopathology, and determine the health costs associated with heroin use careers. The study will provide essential data on how heroin use progresses, and on what factors predict a better outcome for heroin users.Read moreRead less
Molecular And Cellular Characterisation Of Schizophrenia Associated Dysfunction In MicroRNA Biogenesis

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.
Understanding The Pathology Of Muscarinic Receptor Deficit Schizophrenia: A Biochemically Defined Form Of The Disorder.

Summary
Schizophrenia is a group of disorders with similar symptoms and no way of distinguishing the different disorders. In our brain collection 25% of the subjects with schizophrenia have a particular chemical deficit. Screening gene expression in people with schizophrenia, with and without this deficit will give a global picture of chemical differences between the groups. Understanding the differences between sub-groups of people with schizophrenia will aid the development of better drugs for them.
A Prospective Study Of The Psychiatric & Medical Characteristics Of Post-infective Fatigue & Chronic Fatigue Syndrome.

Summary
This project forms the central component of a larger set of studies which investigate competing psychiatric, immunological and infective models of the causes of a number of chronic fatigue syndromes, including post-infective fatigue. The study takes place in western NSW where certain viral illnesses (Glandular Fever, Ross River Virus) and a non-viral infection (QF) are common and have been associated with prolonged fatigue states. The study follows patients from laboratory-documented infections ....This project forms the central component of a larger set of studies which investigate competing psychiatric, immunological and infective models of the causes of a number of chronic fatigue syndromes, including post-infective fatigue. The study takes place in western NSW where certain viral illnesses (Glandular Fever, Ross River Virus) and a non-viral infection (QF) are common and have been associated with prolonged fatigue states. The study follows patients from laboratory-documented infections with appropriate infective, immunological and psychological measures throughout the course of their acute illness, the early recovery period and for the next 12 months. These patients are compared with people who present to their doctor with other forms of medically-unexplained fatigue. Very few previous studies have used an appropriate prospective design and followed patients with documented illness from the onset through to the development of specific forms of chronic fatigue. Further, the study is unique in terms of the range of viral and non-viral agents being investigated. It relies on the combined psychiatric, immunological and infective disease expertise of a group of researchers with an international reputation for the successful completion of such multidisciplinary projects. The initial phase of the study has demonstrated that the research team has the capacity to complete this project. Initial results have already demonstrated the potential roles of psychological and immunological factors in causing some cases of prolonged fatigue. Further, the initial results indicate that two key symptom sets (fatigue, psychological distress) can be adequately measured during the recovery phase and are predicted by differing psychological factors. The study will result in the identification of different psychiatric risk factors to chronic fatigue, assist development of clear diagnostic guidelines for post-infective fatigue and guide relevant aetiological and treatment research.Read moreRead less
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.

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.
