Summary
Over the past four decades problems such as depression, anxiety, self-harm and substance abuse have increased in young people. Recent research indicates that puberty is a time when these problems commonly first emerge. This five-year study of 4000 students will examine a question of whether social transitions that are too soon (e.g. early initiation of sex) or problematic (e.g. bullying from peers) may explain the increase in these health problems as children pass through puberty.
An inability to resist a temptation or repeated failures of self-regulation can lead to 'impulsive' and 'compulsive' behaviours that relate to a host of personal and social problems (eg., excessive eating, gambling, and substance use). Despite this, very little research has studied the neural and psychological underpinnings of these behaviours. My research will take advantage of recent innovations and approaches to fill this void and have implications for diagnosis and treatment.
Ocular Motility In Autism And Asperger S Disorder: Dissociation Of Motor Deficits.

$131,235.00
Summary
We will use ocular motor technology to investigate motor dysfunction in autism and Asperger's disorder, to advance our understanding of the neurobiological bases of these disorders. This will help clarify whether neural networks are differentially disrupted in these disorders, as our previous clinical research suggests. This dissociation and the subsequent development of an ocular motor clincal screen may improve diagnosis, and potentially treatment, of these devastating conditions.

Summary
Mental disorders, such as psychotic and severe mood disorders, are the largest cause of disability in Australia. However, there is still little known about illness onset, relapse and progression. We have developed a clinical staging model with transition points from symptomfree to subthreshold status, to threshold disorder to chronic disability. We will investigate neurobiological and psychosocial factors which increase the risk of progression through these stages and use this model as a basis f ....Mental disorders, such as psychotic and severe mood disorders, are the largest cause of disability in Australia. However, there is still little known about illness onset, relapse and progression. We have developed a clinical staging model with transition points from symptomfree to subthreshold status, to threshold disorder to chronic disability. We will investigate neurobiological and psychosocial factors which increase the risk of progression through these stages and use this model as a basis for examining the effectiveness of interventions, for example to prevent, delay or ameliorate onset and relapse, and promote vocational recovery. Thus major clinical and public health benefits and an understanding of factors that contribute to the onset and progression of illness will result.Read moreRead less

The Centre will focus its activities on the two-way relationship between disrupted sleep and body clock systems and brain disorders. Our goal is to improve brain performance, workplace safety and health outcomes in patients with sleep and circadian dysfunction and in the general community.Read moreRead less

Summary
While it is well known that autism and Asperger's disorder are associated with social, communicative, and behavioural symptoms, it is less well known that affected individuals also have considerable movement and coordination difficulties. For example, these children often have problems with hand writing, walking, hopping, skipping, catching, and running.

For example, these children often have problems with hand writing, walking, hopping, skipping, catching, and running. These skills are very important for success at school; for example, if children are unable to participate in school sports they often feel isolated and rejected from the peer group. Also, hand writing problems have a significant impact on children's academic performance. Our previous research has suggested that there may be particular patterns of motor problems that characterise individuals with autism and Asperger's disorder. Our proposed research aims to use the kinds of 3D motion analysis technology used in the movie industry to capture exactly how people affected by these conditions move and respond to the environment. This study will enable us to highlight particular parts of the brain-motor circuitry that are affected by these disorders and will also enable us to more clearly distinguish how autism is different from Asperger's disorder. Ultimately, it is hoped that our motor investigations will lead to improved assessment and interventions for these disorders.Read moreRead less
Neourobiology Of Human Epilepsy: Genes, Cellular Mechanisms,network And Whole Brain

Summary
The team is comprised of neurologists, molecular geneticists, physiologists and brain imaging specialists and leads the world in the discovery of the genetic causes of epilepsy. They will continue to identify genes underlying epilepsy and study how genetic variations result in development of seizures. Advanced brain imaging will be used to understand the effects of genetic variation on brain structure and function. This study may lead to new diagnostic methods and treatments for epilepsy.
Defining The Epigenetic Origins Of Maternally Inherited Disease.

Summary
Epigenetic (non genetic) changes to the DNA in sperm and eggs can alter outcomes in children. Despite the potential for drugs and diet to mediate some of these inherited effects, the processes involved are very poorly understood. By determining the mechanisms that regulate epigenetic inheritance, this project will improve our understanding of how epigenetic mechanisms acting in the parent, can mediate inherited disease and life-long health outcomes in our children.
Prevalence report by the Australian Advisory Board on Autism Spectrum Disorders (ASD) estimated that 1 child in every 160 children in the 6-12 year-old age group is affected by ASD. There is no cure for ASD and the causes are not understood. We propose that sex hormones may play a role in the development of these disorders. We will test this hypothesis using knockout and transgenic mouse models which have social interaction deficits and brain structure reminiscent of these disorders.
Characterisation Of Eurl, A Novel Gene Implicated In The Etiology Of Abnormal Brain Development And Intellectual Disability

Summary
Intellectual disability affects around one per cent of Australians, and can arise from genetic abnormalities during fetal life, such as through abnormal regulation of gene expression. We have identified a novel gene, known as eurl, which controls brain assembly as well as the ability of neurons to form functional connections within the brain. We will investigate how this novel gene controls brain development, and characterise eurl as a potential therapeutic target for learning and memory.
