This project will conduct the first prospective analysis of acute stress disorder and chronic traumatic stress symptoms in children, develop diagnostic guidelines to identify acutely traumatized children who are at risk of PTSD, and identify biological, cognitive, and familial factors that mediate PTSD development following trauma. Two hundred children (aged 7 - 12 years) who are admitted to hospital following a traumatic injury will be assessed for acute disorder within one month of the accident. They will be also be assessed for heart rate, blood pressure, memory patterns, and family responses during the initial assesment. Parents will also be assessed for their trauma reactions. All participants will be re-assessed at 6-months posttrauma, and again at 18-months posttrauma. These findings will establish the means to identify acutely traumatized children who are at risk of PTSD and open up opportunities for early intervention and prevention of PTSD.Read moreRead less

Summary
Posttraumatic stress disorder (PTSD) is the most common psychiatric condition to develop after trauma. Early intervention of PTSD following a trauma is indicated because chronic PTSD can be resistant to treatment. Early intervention is possible because acute stress disorder immediately after a trauma identifies those people who will develop chronic PTSD.

Early intervention of PTSD following a trauma is indicated because chronic PTSD can be resistant to treatment. Early intervention is possible because acute stress disorder immediately after a trauma identifies those people who will develop chronic PTSD. Although cognitive behaviour therapy of acute stress disorder can effectively prevent PTSD in many cases, many people do not benefit from this treatment because this treatment involves exposure to distressing memories and emotions, and this contributes to many people dropping out of treatment. This project aims to extend the utility of early intervention following trauma by assessing approaches that can be used by most trauma survivors. The project compares early intervention with either exposure, cognitive therapy, combined exposure and cognitive therapy, or supportive counseling. All therapy will be conducted in the initial four weeks and will comprise 6 sessions. Assessments will be conducted posttreatment, six-months follow-up, and one-year follow-up. The outcomes of this project will have significant public health benefits because they will lead to increased treatment effectiveness for acutely traumatized people, and will markedly reduce the incidence of PTSD in the community.Read moreRead less

Recurring attacks over a period of months, or years, forms the basis for the diagnosis of panic disorder. It has until recently been felt that although panic disorder was distressing and disabling, it did not constitute a risk to life. Sufferers often fear that they have heart disease, because of the nature of their symptoms, but have been reassured that this is not the case. Recent epidemiological studies, however, indicate that there is an increased risk of heart risk in patients with panic disorder. Our hypotheses in this research are as follows: That panic disorder is characterised by increased release of the brain chemical messenger, serotonin, which is reversed by drug treatment with the most widely used class of drugs for this disorder, selective serotonin reuptake blockers That changes in an automatic stimulatory part of the nervous system, has primary importance in the disorder, in both genetically predisposing to panic disorder, and in mediating heart risk. That weight gain during therapy, a very common problem, is due to inhibition of brain serotonin release. We will test all these propositions using state of the art clinical scientific methods. Panic disorder has an important cardiological dimension which needs to be better understood for cardiac protection to be achieved in panic disorder patients. Our study of the mechanisms of cardiac risk should provide this. We will also provide very direct, valid measurements of chemical messenger release in the brain of panic disorder sufferers, using our unique methods. These should give a new understanding of the brain chemistry abnormalities of panic disorder, and the mechanism of action of the selective serotonin reuptake inhibitors.Read moreRead less

Summary
Motor vehicle accidents (MVAs) are relatively frequent major life trauma that represent significant life threatening experiences. Not surprisingly evidence suggests that MVAs represent a frequent trigger for the development of post traumatic stress disorder (PTSD), although studies have typically focussed upon adult survivors. Local statistics indicate a significant proportion of children will experience a MVA of sufficient severity to warrant attendance at hospital.

Not surprisingly evidence suggests that MVAs represent a frequent trigger for the development of post traumatic stress disorder (PTSD), although studies have typically focussed upon adult survivors. Local statistics indicate a significant proportion of children will experience a MVA of sufficient severity to warrant attendance at hospital. This project is of significance because it will provide badly needed information about the prevalence and course of emotional and behavioural problems in children following exposure to a serious MVA. More broadly the study should provide valuable information on post-traumatic stress responses in children. Furthermore, it will enable us to identify the factors that place children at particular risk of developing psychological problems following a MVA. This will provide information to help design of interventions to prevent the development of PTSD and other forms of psychopathology following MVAs. Such data will also permit identification of those children who are at particular risk of psychological morbidity after MVA trauma and for whom preventive interventions are most likely to be beneficial.Read moreRead less
How well people perform in everyday situations is often determined by memory function. When required to perform under stress memory performance is often affected. The effect of a psychological stress test on memory function in healthy volunteers and the ability of a dietary supplement, tyrosine, to prevent the effects will be studied. The data may suggest that depletion amino acids is responsible for the decrements in performance that are evident after an acute stressor.
Dopamine Mechanisms Conferring Resilience To Depression: A New Antidepressant Target

Summary
A significant proportion of people who suffer depression fail to obtain effective relief from either drugs or psychotherapy. Accordingly, there is a pressing need to develop new, and more effective, treatments. This project will determine whether certain specific brain pathways that use the transmitter dopamine can be manipulated in their activity so as to increase resilience to depression. This work has potential to provide the foundation for the development a new generation of antidepressants.

Summary
Attention deficit hyperactivity disorder (ADHD) is a common psychiatric disorder of childhood that is marked by age-inappropriate levels of inattention and-or hyperactivity-impulsivity. The disorder appears genetic with a number of different genes likely contributing risk for ADHD. I will use a multi-modal (genetic, cognitive, neurochemical, physiological) approach to increase our understanding of the biological mechanisms leading from gene to disorder in ADHD.

Since 1991 our Australian Twin ADHD Project (ATAP) has developed as one of the world's largest programs on the genetics of ADHD, and in 2001 we published the first text on this topic. In this grant we turn the focus onto environmental influences with the question Why can one identical twin have ADHD, while the other twin has no difficulties? Using the unique resources of the Australian Twin Registry and the WA Twin Child Health Study, we shall work across the country to find over 100 identical twin pairs who are very different in ADHD. In this way, each ADHD affected twin has an unaffected 'control twin', offering a powerful means for comparing the two. Such a study is really only possible in Australia, as no other country has such twin resources for research. The questions we want to consider with these children include the following 1- Twins have a more difficult time before and at birth. To what extent do these problems contribute to differences between the twins? 2- Are there differences in specific aspects of brain functioning? 3- Is it that one twin grows out of their ADHD but the other does not? If so, what distinguishes the children? 4- What is it like growing up with a twin who has ADHD, when you have no difficulties yourself? 5- When one twin has ADHD symptoms, is the family more likely to seek help, as they can see how different this child is form the other twin? Obviously identical twins in wehich only one has ADHD are a very unique group. By covering all aspects of development, from brain functioning to service utilisation, the hope is that this study will provide invaluable insights into this common condition which will help all children and families where the diagnosis of ADHD has been made.Read moreRead less

Children with OCD frequently experience high functional impairment as a result of their symptoms, including deteriorating school performance and poor peer relationships. Family life is often disrupted, causing significant distress and hardship to parents and siblings. However, little research attention has been paid to how families affect and are affected by this disabling condition. This research examines the role of learning in the development, maintenance and treatment of OCD. Specifically, the study aims to: 1. explore the way in which children with OCD process threatening information 2. investigate the influence of parents on children's processing of OCD-relevant information 3. develop and implement the world's first randomised control trial of cognitive-behavioural plus parent training (CBT + PT) for childhood OCD 4. evaluate parent-assisted treatment in comparison to a standard cognitive-behavioural treatment (CBT) and a placebo control 5. examine the long-term maintenance of each type of treatment The outcomes of this project will be: 1. an improved understanding of OCD in children, and their families 2. an increased knowledge of the relationship between parenting processes and OCD symptomatology 3. the development and dissemination of an evidence-based treatment for childhood OCDRead moreRead less

Summary
Approximately 9.7% of the adult population have an anxiety disorder with one of the more common, panic disorder, often with agoraphobia, afflicting 2.4% of the community. Around 8% of patients consulting a GP also have panic disorder (PD). A further 10% of the community experience spontaneous panic, but do not have full PD (termed non-clinical panic).

Around 8% of patients consulting a GP also have panic disorder (PD). A further 10% of the community experience spontaneous panic, but do not have full PD (termed non-clinical panic). People with PD frequently experience clinical depression, about 15% abuse alcohol and non-prescription drugs and PD is associated with an increased risk of suicide. Over time people with PD appear to have an increased risk of heart problems. They also have substantial financial burdens through multiple attendances at doctors' rooms and through restricted employment opportunities. Only just over one in four people with an anxiety disorder consults a health professional for their problems, with most going to their GP. It has been estimated that less than 10% of these people seek the services of a mental health specialist such as a clinical psychologist or psychiatrist. Therefore because of blocks to do with access, cost or embarrassment, many people with mental health problems do not seek face-to-face specialised mental health treatment. People in rural and regional Australia are particularly disadvantaged by limited access to these specialists. We have developed an internet-based treatment program on panic and anxiety for people in the community, and particularly in regional Australia. Early evaluation of this program has found it is more effective than other types of therapist-assisted self-help treatment. The aim of this research project is to compare it to best-practice face-to-face psychological and pharmacological treatment for PD. If the effectiveness of our internet-based treatment is comparable to best-practice face-to-face treatment, its availability will assist the many Australians who suffer from debilitating panic but who are unable to access specialised mental health assistance.Read moreRead less
