Summary
The neurological outcome of the premature infant is of major importance. Approximately 2,600 premature infants weighing less than 1500 grams are born annually in Australasia. Of the approximate 2,400 survivors between 5-15% will have a more major cerebral palsy, i.e. around 200 children per annum. A greater proportion of 25-50%, i.e., upto 1200 children will have a developmental disability that will adversely affect their school perfomance requiring special assistance or repeating grades.

Of the approximate 2,400 survivors between 5-15% will have a more major cerebral palsy, i.e. around 200 children per annum. A greater proportion of 25-50%, i.e., upto 1200 children will have a developmental disability that will adversely affect their school perfomance requiring special assistance or repeating grades. With an increasing number of very prematurely born infants surviving, the absolute number of affected children will continue to rise. Prevention of these disabilities will require an understanding of the cause. The educational and social implications of these high rates of neuro-developmental disability are enormous and the focus of wide international concern. Magnetic Resonance Imaging : It is a major challenge for neonatologists to be able to understand the impact of their therapies and managements on the developing brain. A window into the newborn brain can be seen utilising advanced magnetic resonance imaging techniques in-vivo to investigate these key issues: 1. What is the nature of brain injury in the prematurely born infant? 2. What are the risk factors for brain injury in the prematurely born infant - and are they able to be altered to reduce this risk - e.g. blood pressure management, steroid therapy 3. Is the brain of a prematurely born infant different from that of a full term born infant at TERM equivalent - if so, how is it different? 4. Are there certain postnatal therapies that relate to any alteration in brain structure and chemistry - e.g. postnatal nutrition, modes of ventilation, pharmacological therapies? 5. How does the brain structure relate to function on long term neuro-developmental follow up of our infants at 2 years?Read moreRead less
The Neurophysiology Of Abnormal Motor Development In Preterm Children

Summary
Better neonatal care has improved survival of prematurely born children. While most of these children will have no obvious brain lesion and attend mainstream schools, many will experience motor and cognitive difficulties and problems with social adjustment. However, the physiological mechanisms underlying this dysfunction are unknown. We will study preterm and term born children to elucidate the physiological mechanisms underlying motor and cognitive dysfunction associated with prematurity.

Summary
The high rate of adverse neurodevelopmental outcomes of very premature infants is of major concern. In Australia there are approximately 2600 very low birthweight (VLBW, birthweight <1500 g) or very premature (<30 weeks' gestational age) survivors per annum. A large proportion of these infants (40%-50%) will later develop motor incoordination, cognitive impairment, attention deficits or behavioural problems (up to 1300 new cases per year).

In Australia there are approximately 2600 very low birthweight (VLBW, birthweight <1500 g) or very premature (<30 weeks' gestational age) survivors per annum. A large proportion of these infants (40%-50%) will later develop motor incoordination, cognitive impairment, attention deficits or behavioural problems (up to 1300 new cases per year). There is little research to test the efficacy of early preventive care programs geared to changing the infant's environment (physical management, behavioural regulation, maternal factors). In the proposed study we aim to use a low cost preventive care program at home conducted by physiotherapists and psychologists that has been shown to have utility and efficacy in pilot work, with follow up until 2 years of age. In subsequent studies we would aim to follow this cohort to school age, to determine if there are any lasting benefits of early intervention accompanied by measures of brain growth and structural development using advanced imaging techniques. Any new health care program should result not only in improvements in health, but should be affordable to implement so an economic evaluation will also be undertaken. This study will also utilise novel and advanced MRI brain imaging techniques to understand the complex interaction between brain injury and altered brain development in these infants with the risk and the repsonse to this program of care. In this way the changes in brain connectivity, structure and biochemistry can be formally defined to undertsnad the pathway of any potential benefit from this program.Read moreRead less
Targeting The Immune Cells Of The Brain To Develop Novel Treatments For Neurodevelopmental And Mental Health Problems In Children

Summary
Neurodevelopmental and mental health problems are common in children and cause major impairment and cost to society. This research will define how the maternal immune system while pregnant can affect the baby brain. Using patient studies and laboratory research, this research will result in novel ways to reduce the prevalence and severity of developmental and mental health problems in children and adults, by targeting the immune cells resident in the brain.
Creating A Phenotypic Catalogue Of Synaptic Vesicle Cycling Disorders

Summary
Developmental disorders affect 2-5% of children. In order to understand how these mutations will likely affect neurological function in these individuals, and to develop a tailored care and treatment program, we must first understand how these mutations affect neuronal communication. This research program will identify the underlying cause of neurological dysfunction in a subset of these disorders (synaptic vesicle cycle disorders), affecting 1200-3000 children in Australia alone.
Precision Epigenetics: Targeting The Epigenome To Treat Disease

Summary
Epigenetic marks are changes made to the DNA that allow genes to be switched off in some cells and switched on in others. These marks are critical to normal development and often go wrong in disease. We aim to find genes that add epigenetic marks to the DNA and understand how they co-operate at the molecular level to switch genes off. Our focus is on one such gene, SMCHD1. We are developing new drugs against SMCHD1 to treat incurable neurodevelopmental disorder PWS and muscular dystrophy FSHD.

Summary
This application will develop a new way of treating brain cancer which currently affects 1500 adults in Australia per year with no lasting cures. The average patient with a malignant brain tumour do not survive for more than 12 months. We have discovered a method of restoring a cancer suppressor substance that is lost from brain tumours. If successful, this treatment has the potential to limit or reverse the progression of brain tumours.
