It is imperative that effective interventions be developed and evaluated for children with externalising disorders (e.g. oppositional disorder, attention deficit order and conduct disorder). The prevalence of these problems in the community is high, the prognosis of children is poor, and externalising problems are passed on across successive generations in the same family.

The prevalence of these problems in the community is high, the prognosis of children is poor, and externalising problems are passed on across successive generations in the same family. Childhood externalising problems are also one of the most costly behavioural disorders for society. Many studies have examined the nature and course of externalising problems in older children and adolescents. However, little attention has been paid to the early onset of externalising disorders amongst preschool and early school-age children. Whilst the relationships between family risk factors (e.g. marital discord and maternal depression), parental management styles and children's behaviour problems are widely recognised, the exact nature and direction of these relationships remains largely unknown. This proposal will provide new information about the mechanism through which family risk factors such as marital discord or parental distress influence the onset and persistence of externalising problems in young children, via their effects on parents' behaviour management techniques. This information can then be used to instruct early intervention efforts for parents and families of children at risk of developing externalising behaviour problems.Read moreRead less

Apathy is the state of loss of motivation and emotional withdrawal that occurs in a high proportion of patients with Alzheimer’s disease. These patients require more management and support, given their reliance on others to schedule their activities and initiate behaviours even when they are still capable of performing the activities. In spite of the high frequency of apathy in dementia and the high potential of negative effects on patients and caregivers, little is known about the cause of this phenomenon, its potential influence upon the long-term progression of Alzheimer’s disease, and on its impact upon caregivers’ emotional well-being. The main aim of our proposal is to examine the mechanism, clinical relevance and impact of apathy in Alzheimer’s disease. More specifically, we will determine whether apathy predicts more severe depression, increasing motor problems, and a faster progression of cognitive and functional problems. Using state-of-the-art neuroimaging techniques we will examine the association between apathy and abnormalities in specific brain regions. Finally, we will examine whether caregivers of patients with apathy have relatively more severe emotional problems, a higher care giving burden and poor quality of life.Read moreRead less

Remediation is not effective once a chronic pattern has been established. Recently, research has shown that early signs of psychopathy in children predict chronic antisocial behaviour and lack of responsiveness to traditional treatments. The current research uses a combination of experimental, longitudinal, and treatment outcome studies to examine: the effectiveness with which early signs of a callous-unemotional temperamental style, hypothesised to be an early indicator of psychopathy, can be measured in children, causal factors and correlates of callous-unemotional traits, whether such traits pose a risk for chronic antisocial behaviour, the effects of callous-unemotional traits on responsiveness to traditional family-school based treatments, and the effectiveness of an innovative method for treating it in the early years. The project leads directly to a range of clinical assessment and treatment strategies for children at risk for chronic antisocial behaviour. The project has the potential to substantially improve the effectiveness of current treatment approaches to conduct problems in children that focus on family and school management.Read moreRead less

Summary
During the next three decades the number of persons older than 85 years will more than double, and the health care need of this burgeoning population are assuming greater importance. Recent studies suggest that the prevalence of dementia in Australia will increase from 172 000 cases in 2000 to 588 000 in 2050. This rapid increase in number of dementia cases will result in an increasing burden for caregivers, and in financial terms, for the working-age population.

Recent studies suggest that the prevalence of dementia in Australia will increase from 172 000 cases in 2000 to 588 000 in 2050. This rapid increase in number of dementia cases will result in an increasing burden for caregivers, and in financial terms, for the working-age population. One of the main clinical problems suffered by individuals of dementia is psychological and behavioural changes such as poor insight, irritability and apathy. These problems account for a large proportion of medical expenses, predict early institutionalization, and are associated with poor quality of life of caregivers. Unfortunately, little is known about the true frequency of problems of insight in dementia, about their impact upon caregivers, and about how to best diagnose the problems of loss of insight and judgment in this condition. Our study will examine the frequency and clinical correlates of poor insight and judgment in dementia, it will establish whether these problems predict other common behavioural problems of Alzheimer’s disease such as apathy and dangerous behaviours, and will demonstrate the reliability and validity of a specific instrument to measure insight and judgment in dementia. This will facilitate the early recognition and adequate treatment of behavioural problems in patients with dementia; it will improve patients’ quality of life, and will have a positive impact on both caregivers’ psychological well-being and on clinical practice.Read moreRead less

Post-mortem studies have shown changes in the levels of 'receptors' (keyholes for messenger chemicals in the brain) for serotonin in schizophrenia. In addition, in the treatment of schizophrenia, the more recently introduced 'atypical' antipsychotic drugs are superior to the more traditional 'typical' antipsychotics in terms of efficacy and side-effect profile. Typical antipsychotic drugs act mainly through blockade of receptors for a brain chemical called dopamine. Atypical drugs appear to have additional actions, in particular blocking the effect of serotonin in the brain. This evidence is mostly circumstancial, relying to a large extent on biochemical analysis of brain regions and 'receptors' on which antipsychotics MAY act. It is currently unclear exactly how and where in the brain changes in serotonin activity influence behavioural processes causing schizophrenia. It is also unclear how and where typical and atypical antipsychotic drugs interact with the role of serotonin in schizophrenia. In this project we intend to inactivate specific parts of the serotonin system of otherwise intact, freely moving rats. Using behavioural observation methods relevant for schizophrenia, we will analyze if and how these interventions influence the behaviour of these rats. The results can have important implications for our fundamental understanding of the involvement of serotonin in the brain in schizophrenia.Read moreRead less

It also aims to identify factors that predict the onset of depression in those who do not receive the intervention. The intervention focuses on the training of interpersonal problem solving skills and enhancement of optimistic thinking styles within a classroom-based curriculum. This project extends the current research program of the applicant. The intervention has already been developed and implemented with 1600 young people, with the support of local education authorities. The evaluation uses well-researched measures and includes a control group of adolescents who do not receive the intervention. Around 5% of adolescents experience clinical levels of depression and an even larger percentage show subclinical levels. Depression results in many debilitating consequences such as impaired school, work and social functioning and is also a risk factor in adolescent suicide. The prevention of mental health problems is a priority for Commonwealth and State governments and yet there is minimal research to demonstrate the effectiveness of preventive interventions, particularly in the area of depression. If the present study demonstrates a positive outcome, it will provide important guidelines as to preventive materials that should be included in the school curriculum. It is predicted that: a) the intervention will be associated with lower levels of depression over the 4 year follow-up, particularly for adolescents who are assessed as showing mild symptoms of depression, poor problem solving skills or pessimistic cognitive style prior to intervention b) risk factors for the development of depression in adolescents who do not receive the intervention will include initial mild symptoms of depression, poor problem solving skills and pessimistic attributional style.Read moreRead less

A general relationship between alcohol-substance abuse and self-harming - suicidal behaviour has been recognised for decades. From the point of view of diagnosed substance abusers there is a correspondingly high incidence of suicide and self-harm. The lifetime risk for suicide in alcohol dependence is higher than for schizophrenia or affective disorder. Despite the public health and personal burden associated with suicidality, the general lack of skills and focus on management of self-harm in specialised drug and alcohol services is of great concern. In this study, all patients attending drug and alcohol services will be screened for suicide risk, and offered a comprehensive psychological treatment to reduce suicide risk and the use of alcohol and other substances.Read moreRead less
