Summary
Subjective memory concerns are common in older adults, but it is uncertain how they relate to Alzheimer’s disease (AD) biomarkers. Novel neuroimaging techniques have been developed for measuring tau deposition, a hallmark feature of AD. Using this technique, I aim to determine whether tau is sensitive to certain types of subjective concerns. My findings will reveal which concerns are indicative of AD risk, and which arise from unrelated factors, such as inattention or stress.
Modifying The Trajectory Of Insidious Late Life Cognitive Decline Using Computerised Cognitive Training

Funding Amount

Summary
Supervised, group-based computerised cognitive training (CCT) is a safe and effective intervention to maintain cognition in healthy older adults. This project will examine the extent to which CCT can attenuate or even reverse the rate of decline in older people with previously documented cognitive decline, as well as strategies to maintain CCT effects in the long term.
Studying precancerous stem cells that cause T cell leukaemia. Recent research has identified abnormal stem cells that are the cause of T cell leukaemia. They are also resistant to therapeutics suggesting that they could be a cause of relapse. The aim of this project is to determine the abnormal pathways that cause these cells to become immortal and to determine new therapeutic strategies to eliminate them.
The role of P2X7 and P2X4 receptor mediated innate phagocytosis in pathogenesis and treatment of neurodegenerative diseases. This project will identify how inherited variation in two proteins of the brain can accelerate the removal of neurones and predispose to a range of neurodegenerative diseases. Knowledge of the biological basis of this finding will allow a search for new compounds which will slow and protect against this form of neurodegeneration.
Improving neuronal cell function with cell permeable copper complexes. Metal-based drugs offer an exciting new approach to treatment of neurodegeneration. However, little is known about how cells metabolise these drugs and this information is critical for further drug development. This project will determine how metal-based drugs are metabolised by neuronal cells and how this may result in therapeutic benefit.
Thalamocortical Neural Circuits In Higher Order Cognitive And Sensory Processing

Summary
Schizophrenia, depression and dementia are devastating disorders with problems in thinking and sensory perception, but the neural circuits causing these symptoms are not known. I will use new optical and genetic tools in mice to identify the cortical and subcortical circuits required for complex touchscreen tasks, the same tasks to assess patients. Identification of neural circuits that underlie clinical symptoms will increase our understanding of these disorders and improve treatments.
Understanding the contribution of neuroinflammation in acute and chronic neural injury. A major focus of this project will be investigating the involvement of neuroinflammation in neural cell damage. It will explore how neuroinflammation contributes to this damage in both acute and chronic neuropathologies.
The Efficacy Of N-acetyl Cysteine As An Adjunctive Treatment For First Episode Psychosis

Summary
First episode psychosis may foreshadow devastating, chronic illness. Psychosis follows a staged, progressive pathway. There is evidence to suggest illness progression can be diminished and perhaps even averted if appropriate treatments are given at the early stages of illness. This project will test if N-acetycysteine (NAC) administered to young people who have experienced a first episode of psychosis can help prevent this early psychotic experience from developing into a chronic disorder.
Improving Physical Health Outcomes For Young People With Psychotic Disorders

Summary
Enduring psychotic disorders are associated with a reduced life expectancy by 25 years, which is mainly due to cardiovascular disease. This project will produce a training package that will improve clinician’s skills and knowledge of screening and treatment for physical health risk factors in young people with psychosis. This project will result in the development of an intervention for reducing the prevalence of these cardiovascular risk factors known to contribute to this early mortality.
