In particular, in the area of personality development, there are a number of theories concerning the importance of childhood experience and developmental stresses on later personality, development, psychological functioning and physical health. More recently there has been debate on the accuracy with which adults areable to remember traumatic experiences in childhood. This study will follow a group of 808 primary school children who were exposed to the 1983 Ash Wednesday bushfires in SOuth Australia. They were involved in a study which examined them two months, eight months and twenty six months after the disaster. This rich descriptive set of information about these children and their families forms an objective data base against which their adult recall of the experience can be judged. The symptoms of these children were also documented at the time as was their disaster exposure. The impact of this one event, in the context of the other developmental influences will be examined as determinants of their adjustment in adult life. Finally, there has been an increasing interest in the way that previous traumatic exposure influences the nature of the hormonal response to stress. Using a test of functioning of the cortisol system, the stress response of this population will be compared with a control population who were also studied at the time of the original disaster.Read moreRead less

The only studies published in professional journals have been produced by members of the applicant team. The results indicate that approximately 50% have suffered gross human rights violations including torture, detention in concentration camps and brainwashing, and 37% are affected by ongoing posttraumatic stress disorder (PTSD) - terrifying memories of past abuses, avoidance of experiences that trigger such memories, social withdrawal, and constant anxiety. The research has also shown that psychiatric symptoms may be worsened by the fears and insecurities associated with the asylum seeking process, but the exact impact of stresses such as rejection of their primary application at 2-3 months, could not be determined. We therefore aim to conduct the first study of its kind that traces the impact of such stresses on the mental health of asylum seekers. In addition, we will track asylum seekers' general health problems and the difficulties they may experience in accessing basic medical health services. This evidence will provide scientific confirmation of how stress can worsen PTSD; indicate that some asylum seekers may be in special need of support throughout the asylum assessment process; assist policy makers to re-assess the methods and processs of assessing asylum claims; and provide impetus to establishing better services for the medical and psychiatric problems faced by asylum seekers.Read moreRead less

Summary
Our 2004 East Timor study showed that men who suffered abuses remain angry. We will follow-up these men to see if those who remained angry were more likely to be involved in social unrest and violence. We will also find out what factors make angry men more likely to act violently. This study will provide information to help agencies assist men overcome anger to avoid future violence.

The cause of the illness is still unclear and the underlying neurochemical changes are different for the manic phase compared with the depressive phase. The current treatments for BPAD are limited in scope and not biochemically well understood. There are gender differences in the presentation and outcomes for BPAD which adds to the complexity of the illness. We are proposing a study to develop a new type of treatment for the manic phase of BPAD and are exploring the use of anti-estrogens in women with mania. The background to our proposed study comes from a few case reports suggesting that anti-estrogen agents such as progesterone and tamoxifen may be useful adjuncts to treatment. We conducted a small pilot study comparing the addition of oral tamoxifen with oral progesterone and placebo in 10 women with mania and found that the women who received tamoxifen made significantly better improvements in their manic symptoms over a 28-day trial. The research study we are now proposing is a larger, three-arm, double blind, placebo controlled, 28-day adjunctive study in women with mania to expand and clarify our pilot study findings. Patients in our proposed study would receive either 40mg per day tamoxifen or 20mg per day progesterone or placebo in addition to standardised lithium medication. We will measure enzyme activity (protein kinase C) and estrogen-progesterone levels to understand more about the mechanisms of action by these new hormone treatments. BPAD is a crippling disorder and if we are successful, then tamoxifen treatment may be an important new treatment. This proposed study will also shed new light on some of the neurochemical mechanisms underlying BPAD as well as opening up the new area of hormone treatments for serious mental illness.Read moreRead less

The underlying pathology of the illness remains unknown. This application seeks funding to use new technologies to screen approximately 60% of the expressed human genome and proteome to determine which genes are being differentially expressed in two regions thought to be important in generating the symptoms of the illness, the frontal cortex and hippocampus. This project will generate a large amount of data, however by comparing the data from subjects with schizophrenia to that from control subjects and subjects with bipolar disorder who were psychotic and being treated with antipsychotic drugs close to death will allow us to identify changes that are specific to schizophrenia. Genes that are expressing different levels of mRNA and protein will become prime targets for future investigations as they are likely to be central to the pathology of the illness.Read moreRead less

Depression is a treatable illness and the majority of patients will respond to anti-depressant medication, a form of psychotherapy or a combination of these. However, a significant percentage of patients with depression fail to respond to these therapies and currently require electroconvulsive therapy (ECT). This entails the complications and costs of multiple anaesthetics, memory impairment and substantial social stigma. Transcranial magnetic stimulation is being researched as a potential alternative for these patients. It is administered to patients who are awake and alert and appears to have fewer side effects. TMS uses the unique properties of a magnetic field to produce or disrupt electrical activity in superficial areas of the brain, targeted to the areas thought to be involved in the cause of depression. Our research study will compare the two most promising types of TMS with an inactive or placebo condition. This is important to establish that the effects of TMS arise from the actual stimulation and to investigate whether one of two types of TMS administered is superior. We will administer this treatment for between 2 and 4 weeks and assess the response. We anticipate that our research will contribute to the development of TMS as a treatment methodology for this important patient group. It is crucial that a new treatment be thoroughly evaluated prior to wide dissemination of it in clinical practice. We will help define the effectiveness of this treatment and the most appropriate way in which it can be administered.Read moreRead less

The illness is characterised by aberrant mood swings resulting in periods of mania and depression with reversion to normal behaviour between episodes. The condition has a severe impact on sufferers, being demonstrated to be the sixth most disabling disorder in the WHO Global Burden of Disease report and increasing the risk of suicide fifteen-fold. There is a pressing need to define more clearly the biological basis of bipolar disorder as a necessary prerequisite to improved diagnosis and treatment. The underlying causes of bipolar disorder remain unknown. However, family studies reveal the high heritability of bipolar disorder and this familial clustering provides an opportunity to use genetic approaches to identify the predisposing genes. The long-term aim of our research is to investigate the biology of those genes that either cause or predispose to bipolar disorder. We have previously reported strong evidence for a novel bipolar disorder susceptibility gene on chromosome 4, a finding which has subsequently been reproduced in several independent studies. Consequently, we hypothesise that there is a gene located on chromosome 4 that predisposes to bipolar disorder. The aim of this proposal is to identify the chromosome 4 bipolar susceptibility gene and understand how the gene causes bipolar disorder. Identifying the genes responsible for bipolar disorder will allow us to define and understand the biological basis of this severe psychiatric condition. This will ultimately lead to major improvements in the ability to diagnose, treat and prevent the illness.Read moreRead less
