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

Summary
Drug abuse is the greatest single preventable risk factor for physical illness and death in Australians . Our understanding of the neural and cognitive mechanisms that contribute to the transition from drug use to addiction is not yet complete. The current proposal investigates cognitive control dysfunction, most notably the impulsivity for reward seen in drug addiction that is known to predict the transition from drug use to addiction and relapse during treatment.
Investigating Cortical Plasticity And Connectivity In People With Chronic Low Back Pain And Controls Using Combined TMS_EEG

Summary
Little is known about the factors that predispose the development of chronic low back pain or what changes underpin effective treatment. Brain changes, thought to reflect adaptive processes are associated with chronic pain, but the extent of their contribution to CLBP is unknown. By measuring the adaptability of brain changes in people with CLBP I will determine if they differ from healthy controls in a way that predisposes them to develop chronic pain and is related to treatment response.
Health-Related Quality Of Life In Intractable Paediatric Epilepsy: Using A New Measure To Improve Management

Summary
Until recently there was no adequate measure to assess the quality of life of children with epilepsy. Our Australian centre was the first to develop, validate and publish such an instrument; the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). We now aim to collect more data using the QOLCE to gain further understanding of the effects of epilepsy and its treatment on the quality of life of children. We will determine if surgery in children stops seizures and improves quality of life. ....Until recently there was no adequate measure to assess the quality of life of children with epilepsy. Our Australian centre was the first to develop, validate and publish such an instrument; the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). We now aim to collect more data using the QOLCE to gain further understanding of the effects of epilepsy and its treatment on the quality of life of children. We will determine if surgery in children stops seizures and improves quality of life. We also aim to find out if children with different types of epilepsies have unique quality of life issues. Finally, we aim to determine if the quality of a child's life depends on how well they are thinking and learning or how often they are having seizures. We will conduct this study in children with difficult epilepsy recruited from three major children's hospitals (Sydney Children's Hospital, the Children's Hospital, Westmead, Miami Children's Hospital, Florida USA) using a well designed methodology. Each child will have their particular type of epilepsy characterised using video and brain wave analysis. Each parent and older child will receive a quality of life package including the QOLCE to assess life function. In addition, all children will have an assessment of their thinking and learning by a child psychologist. At the completion of this project we will have established whether surgical treatment in children with epilepsy stops seizures and improves quality of life. This will allow clinicians and parents to better understand the effects of surgical treatment in this population. In addition, we will determine if problems in quality of life are associated with specific types of epilepsy. This information can be used to counsel families and tailor interventions and treatments. Finally, we will know whether a child's quality of life is determined by problems with thinking and learning and-or seizures.Read moreRead less
Cognitive Function And Fatigue In Cancer Patients After Chemotherapy

Summary
Many patients complain of tiredness after chemotherapy and some experience problems with memory, concentration, thinking and other aspects of mental function. Studies have confirmed that some women with breast cancer suffer these effects after chemotherapy and that they can last a long time. Although generally subtle they can affect quality of life and ability to function. Little is known about the causes of these side-effects. Possible causes include blood clotting in small vessels of the brain ....Many patients complain of tiredness after chemotherapy and some experience problems with memory, concentration, thinking and other aspects of mental function. Studies have confirmed that some women with breast cancer suffer these effects after chemotherapy and that they can last a long time. Although generally subtle they can affect quality of life and ability to function. Little is known about the causes of these side-effects. Possible causes include blood clotting in small vessels of the brain and release of molecules called cytokines, as a result of chemotherapy. Hormonal changes and induced menopause might also contribute to these effects in women. Here we propose to evaluate men and women who either receive chemotherapy to prevent recurrence of colorectal cancer, or who are followed without such treatment after surgery. Patients will complete a questionnaire that assesses their level of fatigue and participate in tests of mental functioning, before, during and at intervals after treatment. Possible causes of fatigue and cognitive problems will be studied by measuring products in the blod that indicate blood clotting, levels of cytokine molecules that might cause these symptoms and levels of sex hormones in both men and women. This may lead to further studies to help reduce the burden of fatigue and cognitive impairment from chemotherapy. The goals of our study are to provide comphrehensive information about important side-effects of cancer treatment and to examine the mechanisms that may cause them. This information is important for supporting people living with cancer and for subsequent research to develop interventions that will promote healthy lifestyles during and after treatment for cancer.Read moreRead less

Summary
To reduce dementia burdens in the community, cost effective and targeted early regenerative strategies are critical. Engaging in frequent aerobic exercise is one strategy that can delay the onset and slow the progression of dementia. However, prescription is limited by an incomplete understanding of how exercise positively influences brain health. Here I will investigate the influence of current exercise levels, intensity and exercise environment on brain health in adults at risk of dementia.
