Summary
Psychiatric and substance use disorders are associated with significant morbidity and mortality. Recent evidence points to discrete brain networks as being critically involved in the neurobiology of these disorders. Using novel brain imaging techniques, this research will increase our knowledge of how these brain networks are involved in these disorders. This will represent an important step towards elucidating their biological underpinnings and improving outcomes for affected patients.
The cognitive neuroscience of executive control: behavioural, physiological and genetic mechanisms. How genes influence our human abilities to think, reason and control behaviour has puzzled scientists for decades. The human genome project has allowed us to ask how individual genes influence these capacities. Understanding the genetics of these abilities provides a solid platform from which to launch gene discovery projects in clinical disorders where these abilities are compromised.

How genes influence our human abilities to think, reason and control behaviour has puzzled scientists for decades. The human genome project has allowed us to ask how individual genes influence these capacities. Understanding the genetics of these abilities provides a solid platform from which to launch gene discovery projects in clinical disorders where these abilities are compromised. The current project is directly relevant to the genetics of mental disorders, such as attention deficit hyperactivity (ADHD), that place a large burden, both financially and emotionally, on our society. Understanding the genes and biological pathways that increase risk for mental disorders will ultimately lead to improved treatments for these conditions.Read moreRead less
Genes, neuroanatomy and family process: Predicting adolescent anxiety and depression. Whilst significant gains in outcomes have been obtained in other areas of health by focusing on early intervention and prevention, in the mental health field this approach has been limited by the paucity of developmentally targeted treatment and prevention strategies. This study will provide unique information regarding the risk processes that are operating during early and late adolescence, and will inform us ....Genes, neuroanatomy and family process: Predicting adolescent anxiety and depression. Whilst significant gains in outcomes have been obtained in other areas of health by focusing on early intervention and prevention, in the mental health field this approach has been limited by the paucity of developmentally targeted treatment and prevention strategies. This study will provide unique information regarding the risk processes that are operating during early and late adolescence, and will inform us about how the family environment can act to modulate the impacts of biological vulnerability on risk for mental disorder. This project will contribute to our understanding of who, and what, to target in early intervention and prevention strategies.Read moreRead less
Studying the effects of repetitive transcranial magnetic stimulation with near Infrared spectroscopy. Repetitive transcranial magnetic stimulation (rTMS) is increasingly being used as a tool in studying human and animal brain function and in the treatment of brain disorders but there are fundamental gaps in our understanding of its basic mechanisms of action and hence our capacity to optimise protocols. This research will use near infrared spectroscopy to study the range of potential ways of alt ....Studying the effects of repetitive transcranial magnetic stimulation with near Infrared spectroscopy. Repetitive transcranial magnetic stimulation (rTMS) is increasingly being used as a tool in studying human and animal brain function and in the treatment of brain disorders but there are fundamental gaps in our understanding of its basic mechanisms of action and hence our capacity to optimise protocols. This research will use near infrared spectroscopy to study the range of potential ways of altering brain activity with rTMS. It will substantially enhance the applicability of the technique ultimately improving our knowledge of human and animal brain function and outcomes for patients with depression and other disorders. It will help reinforce Australia as a leading country in the development of brain stimulation techniques.Read moreRead less
Preconception Determinants Of Child Health And Development: A 4-year Follow Up Of Offspring Born To The Australian Temperament Project

Summary
This project will follow offspring born to a large population cohort study that has tracked the mental health and wellbeing of around 2000 participants across 30 years prior to parenthood. The aim is to understand how the lives parents lived before conception, as well as events during pregnancy, shape social and emotional outcomes for their children. Results will inform radically new approaches to promoting child health and development across generations.
Continuity and change in the development of young children with autism. Autism is a severe condition affecting social interaction, communication, behaviour and interests. Parents of children with autism experience high levels of stress associated with the burden of caring. There is a high societal cost associated with the care of people with autism. Research shows outcome in autism is poor, but that early intervention may improve outcome. This project will identify specific early precursors of a ....Continuity and change in the development of young children with autism. Autism is a severe condition affecting social interaction, communication, behaviour and interests. Parents of children with autism experience high levels of stress associated with the burden of caring. There is a high societal cost associated with the care of people with autism. Research shows outcome in autism is poor, but that early intervention may improve outcome. This project will identify specific early precursors of autism which predict outcome. This will allow the development of targeted intervention to give children the best possible start in life and improve longterm outcome. Improvement to the outcome of people with autism will considerably reduce parental and family burden and cost to the community.Read moreRead less

Summary
Healthy ageing is characterised by low level of disability, high cognitive and functional capacity, and an active engagement in life. The most important ingredient of healthy ageing is a healthy brain, bereft of age-related diseases and dysfunction. Brain ageing and brain diseases are determined by multiple genetic factors that interact with environmental influences. The genes are multiple, the majority of which have a small influence. This study is an attempt to identify some of these genes and ....Healthy ageing is characterised by low level of disability, high cognitive and functional capacity, and an active engagement in life. The most important ingredient of healthy ageing is a healthy brain, bereft of age-related diseases and dysfunction. Brain ageing and brain diseases are determined by multiple genetic factors that interact with environmental influences. The genes are multiple, the majority of which have a small influence. This study is an attempt to identify some of these genes and investigate their interactions with environmental factors. It will use a unique resource, the NHMRC Australian Twin Registry (ATR) to identify elderly twins, and will also include the siblings of these twins so as to increase the ability to identify the important factors. The participants, who are listed on the ATR and recruited from NSW, Queensland and Victoria, will receive detailed neurological, psychiatric and cognitive assessments, and will undergo brain MRI scans. Their blood samples will be used to measure key chemicals that may affect brain ageing and to extract DNA for genetic tests. They will be followed-up every two years thereafter, and changes in their brain structure and cognitive functioning will be examined. Available statistical models will be used to examine gene-environment interactions and specific genes will be explored for their contribution to the additive genetic effects. This study will yield an important resource for national and international collaborations and has the potential to discover new genes.Read moreRead less
Attention deficit hyperactivity disorde(ADHD) is the most prevalent mental disorder of childhood affecting around 7.5% of Australian school age children. The disorder is strongly genetic and causes significant impairments in academic functioning, family and peer relations with sufferers at increased risk for drug abuse. Identification and characterisation of rare mutations will enhance our knowledge of the neurobiology and advance the search for next generation drug treatments for the disorder.
