Summary
Dementia is recognized as an increasingly important factor affecting quality of life as people age. Deaths from heart disease are declining, in part due to improved surgical techniques and to the use of less invasive methods to keep arteries open such as coronary stenting. It is now well known that 20 to 60% of patients experience some degree of impairment in thinking ability (cognitive impairment) after cardiac surgery, that this will persist in some of these individuals for years and may incre ....Dementia is recognized as an increasingly important factor affecting quality of life as people age. Deaths from heart disease are declining, in part due to improved surgical techniques and to the use of less invasive methods to keep arteries open such as coronary stenting. It is now well known that 20 to 60% of patients experience some degree of impairment in thinking ability (cognitive impairment) after cardiac surgery, that this will persist in some of these individuals for years and may increase the risk of long-term problems. Cognitive impairment affects people in many ways. While it is not yet known whether the occurrence of cognitive impairment predisposes to dementia, it is thought that Mild Cognitive Impairment (MCI) may do so. We propose to explore the link between MCI and Post Procedural Cognitive Deficit (PPCD) in patients with coronary disease from before the first point of objective diagnosis, i.e. prior to the coronary angiogram, and over a 12-month period, through and subsequent to further treatment interventions such as stenting or cardiac surgery. Our Pilot data suggest that PPCD does indeed occur after angiography, and we propose to identify how long this lasts, whether MCI predisposes to it and whether it is better to wait until it resolves before further interventions are undertaken. In this way we hope to identify the safest treatment strategy for patients with coronary disease that will minimize the occurrence of Cognitive Deficit and possibly longer-term cognitive changes after investigation and treatment for their symptoms.Read moreRead less
Functional Electrical Stimulation Assisted Cycling (eStimCycle):A Novel Intervention To Improve Outcomes In The Critically Ill

Summary
The legacy of critical illness leaves millions of survivors worldwide with long lasting deficits in physical and brain function as well as anxiety, depression and post-traumatic stress disorder. Early rehabilitation may prevent or minimise these effects. This study evaluates the effectiveness of functional electrical stimulation of muscles with assisted in-bed cycling (eStimCycle) on muscle bulk, strength, physical and brain function at hospital discharge, 6 and 12 months.
Estimating And Alleviating The Impacts Of Age-Related Sensory Decline

Summary
Sensory loss and dementia disproportionately affect older adults, often co-occur, and are the two leading contributors to disability burden among older Australians. This research will investigate the consequences that hearing and vision loss have for older adult health and wellbeing, informing strategies to reduce the disability burden of age-related sensory loss. These impacts include cognitive decline and dementia, mental health, quality of life, disability and independent living.
A Scalable Intervention For Increasing Vigorous Physical Activity Among Older Adolescents: The ‘ Burn To Learn ’ Cluster RCT

Funding Amount

Summary
Physical inactivity has been described as a global pandemic and only 15% of Australian adolescents are sufficiently active. The pressure to perform in major school assessments drives many older adolescents to sacrifice physical activity to maximise academic performance. Our team has designed a time-efficient solution to increase physical activity in senior high school students using high intensity interval training which will be evaluated using a cluster randomised controlled trial.
The ability of humans to detect and be aware of errors in behaviour is a fundamental aspect of human cognition. As the saying goes: "To Err Is Human". This project seeks to understand how individual differences in our genetic makeup contribute to our ability to detect and be aware of errors in our behaviour. Understanding the biological systems underpinning error monitoring may assist in the treatment of many psychiatric disorders which are marked by poor awareness of behaviour.
This study investigates how much an individual's genes and environment account for the wide variation in brain structure and function. Using brain imaging we examine in what way the connectivity of the brain of identical and non-identical twins is the same or different from that of their co-twin, and carry out analysis of their DNA to identify some of the genes involved. This will provide fundamental information on genetic mechanisms influencing variation in brain structure and function.
Cognitive Impairments And Post Traumatic Stress Symptoms In Children With Traumatic Brain Injury: A Longitudinal Study

Summary
Traumatic brain injury in children is common with more than 2000 new cases a year in Queensland and Victoria alone. Many children who experience a brain injury go on to have long-term difficulties such as significant educational and social problems. Post-traumatic stress occurs in children following traumatic physical injury. However it is not clear to what extent this is so for children who have received a traumatic brain injury.

Many children who experience a brain injury go on to have long-term difficulties such as significant educational and social problems. Post-traumatic stress occurs in children following traumatic physical injury. However it is not clear to what extent this is so for children who have received a traumatic brain injury. Furthermore, when there is a traumatic brain injury and traumatic stress, it is not clear how these interact, how they influence long-term outcomes, and what factors such as pre-injury functioning and family support and distress mediate outcomes. These issues are very important since effective rehabilitation of children following traumatic brain injury is essential to maximise long-term functioning and minimise disability. To be effective, rehabilitation must be guided by the knowledge about key factors that determine the recovery process. This study aims to provide answers to these questions by following two cohorts of children (aged 6-14) over 18 months after receiving a traumatic brain injury. In total 240 children will be recruited from Brisbane and Melbourne hospitals. They will be assessed at three, six, twelve and eighteen months post-injury using measures of cognitive, psychological and social functioning. Information on parent distress and behaviours will also be obtained. The information obtained will provide the basis for the development of a specific rehabilitation strategy for children with traumatic brain injury, including information on strategies to help prevent any confounding impact of post-traumatic stress on recovery.Read moreRead less

Summary
The persistence of breathing problems from infancy to later life is a complication of premature birth with lifelong consequences. Breathing problems often occur together with lung disease, but prematurity can also affect heart and blood vessel development, and weakness of the main breathing muscle. We will find out how much the heart, lungs and diaphragm contribute to breathing problems in babies; helping us to better predict, diagnose and treat severe breathing problems in babies born preterm.
The development of predictive brain function in preschool children. This project aims to track developmental changes in brain activity and connectivity in typically developing three-to-six year-old children. The preschool years are a time of huge change in children's cognitive abilities, but little is known of the corresponding changes in brain function.

This project aims to track developmental changes in brain activity and connectivity in typically developing three-to-six year-old children. The preschool years are a time of huge change in children's cognitive abilities, but little is known of the corresponding changes in brain function. This work will use child-optimised magnetoencephalography to test the hypothesis that early cognitive development is characterised by refinement of the brain's innate ability to generate predictions about the sensory environment. The resulting insights could improve understanding of neurodevelopmental disorders such as autism.Read moreRead less
Dynamics of word recognition: new insight from the reach-to-touch paradigm. This project will introduce a new behavioural reach-to-touch paradigm for studying basic cognitive processes such as word recognition. The advantage of this paradigm is that it is able to measure cognitive processes moment-by-moment as they unfold over time. This will provide new insights into the temporal dynamics of basic cognitive processing.
