Summary
Concussion is one of the most common neurological injuries and represents a significant public health issue in Australia. The most common consequences of concussive injuries are reduced attention, slowed response speeds and memory impairment. These cognitive processes are critical for performing common day-to-day activities in childhood and adolescence (e.g. acquiring new knowledge and skills, attending to school work). Approximately 20% of concussive injuries occur during participation in organ ....Concussion is one of the most common neurological injuries and represents a significant public health issue in Australia. The most common consequences of concussive injuries are reduced attention, slowed response speeds and memory impairment. These cognitive processes are critical for performing common day-to-day activities in childhood and adolescence (e.g. acquiring new knowledge and skills, attending to school work). Approximately 20% of concussive injuries occur during participation in organised sport. In adult populations, there are now evidence-based guidelines for the diagnosis and management of concussion in sport. Few well-controlled studies exist to identify the frequency and outcome of such injuries in child and adolescent populations, and there are currently no guidelines for diagnosis and management of concussion in children. Further, the academic and social consequence of concussion for the child remains unknown. This study will investigate the cognitive and behavioural outcomes of concussion in young children and adolescents and will use this information to modify and validate currently available adult concussion diagnosis and management paradigms for application with this population. This study will also investigate risk factors for poor outcome following concussion in children and adolescents, and provide age-appropriate data for use in the medical, behavioural and educational management of concussed children and adolescents. A total of 3000 children aged between 10 and 18 years will be recruited to participate in this study. All participants will undergo a baseline evaluation consisting of memory and attention tests, a behavioural rating scale, and measures of educational ability. Participants parents will also provide general health and demographic information. Children who are concussed during the year will be re-assessed within 48 hours of injury and again at 5 days, 10 days and 30 days post-injury to track recovery.Read moreRead less
Wernicke-Korsakoff syndrome is a common and frequently undiagnosed neurological disease due to thiamine deficiency. The condition leads to cognitive and neurological disability and mostly affects people with alcohol dependence. Wernicke-Korsakoff syndrome is eminently treatable with thiamine, although we have insufficient knowledge regarding the best dose of thiamine to treat the condition. This project proposes two controlled trials to evaluate treatment effectiveness of thiamine for Wernicke-K ....Wernicke-Korsakoff syndrome is a common and frequently undiagnosed neurological disease due to thiamine deficiency.

Autism and its milder forms affect approximately 6 per 1,000 children. The biological basis of the disorder is unknown, so considerable research is being invested in identifying cognitive processes that are atypical in children with autism because this may help identify key areas of the brain affected by the disorder. This research has established that children with autism often outperform their typically developing peers on tasks that require detailed analysis of visual information. In contrast ....Autism and its milder forms affect approximately 6 per 1,000 children. The biological basis of the disorder is unknown, so considerable research is being invested in identifying cognitive processes that are atypical in children with autism because this may help identify key areas of the brain affected by the disorder. This research has established that children with autism often outperform their typically developing peers on tasks that require detailed analysis of visual information. In contrast, visual tasks that require integrating information often reveal impaired performance in children with autism. Human vision is achieved through two pathways in the brain - a dorsal pathway most responsive to changing (e.g. moving or flickering) stimuli and a ventral pathway most responsive to enduring stimulus features (e.g. colour, pattern). Increasingly complex visual processing is achieved at higher levels in each pathway through integrating information from lower levels. One objective of our work is to identify which levels of processing in each of the dorsal and ventral pathways show atypical functioning (either enhanced or impaired) in autism. We will do this using tasks designed to establish thresholds for different perceptual judgements, such as identifying patterns in a field of dots. Children with autism will be compared to typically developing children and also to children with Specific Language Impairment (SLI). This will enable us to establish whether the same profile of strengths and weaknesses in perception and cognition are observed in autism and SLI, or whether they can be distinguished on this basis. The significance of the work is that it will advance considerably the understanding of atypical visual processing in autism and SLI. Also, by identifying perceptual and cognitive differences in children with autism, we may be able to develop tests to identify infants affected by the disorder and commence remediation at an early age.Read moreRead less
Testing theoretical models of age and disease related changes to inform prevention. Pathological brain changes associated with future cognitive decline become detectable in the 40s or earlier. Yet little is known about what constitutes normal brain ageing in mid-life. Using a number of neuroimaging and epidemiological techniques this project will scrutinise brain and cognitive ageing in middle-age and their significance.

Summary
Until recently it has been assumed that variation in blood sugar levels within the normal range in non-diabetics is innocuous. Recent findings from our team suggest that high normal sugar levels present risks to brain and cognitive health. This project will investigate in detail the extent to which higher sugar levels in healthy individuals living in the community are associated with brain changes over time, and whether these changes are associated with cognitive decline in middle- and old-age.

Summary
In the past 20 years, my group has become the world-leader in adolescent health research. We have published papers that have transformed thinking on adolescent health. In the next five years, we will undertake research into the effects of puberty on mental health, explore the effects of health prior to pregnancy on a healthy start to life for the next generation and undertake global research that will enable the roll-out of new multi-billion dollar investments in adolescent health.
Neurodevelopment During Adolescence: A Longitudinal Imaging Study

Summary
Adolescence is a risk period for the emergence of psychiatric disorders. It is also a time of rapid change in the brain, but few studies have detailed changes in neurodevelopment during this sensitive period. We will study twins from early adolescence and use brain imaging to investigate changing brain patterns as the brain matures, and thereby, gain insight into factors responsible for increasing our risk or resilience for major mental health conditions and optimal points for intervention.
