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.

Summary
The recent Child and Adolescent component of the National Mental Health Survey identified Attention Deficit Hyperactivity Disorder(ADHD) as the most common behavioural problem among Australian children. 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.

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
Neurocognitive Correlates Of Transition From Ultra-high Risk Mental State To Schizophrenia

Summary
Understanding the changes in the brains of young people when they are developing a severe mental illness is the objective of this research. State-of-the-art brain imaging and brain function data will be prospectively collected from more than 500 young people considered at ultra high risk of developing schizophrenia, the most severe of mental illnesses for which no cure exists. We aim to identify early brain changes in schizophrenia, thus allowing for more effective early intervention.
