Local Sleep In The Awake Brain: An Underlying Cause Of Neurobehavioural Deficits In Sleep Apnea?

Summary
Obstructive sleep apnea (OSA) is a common sleep disorder which significantly impacts daytime functioning leading to excessive sleepiness, and problems with attention and thinking. Currently, the causes for cognitive impairment in OSA (including attentional lapses and performance deficits) are poorly understood. In the awake state, groups of neurons can briefly go “offline” as they do in sleep. These periods of “local sleep” may explain impaired task performance in OSA.
Schizophrenia is a serious and debilitating psychotic illness often characterized by delusions: fixed, false beliefs that preoccupy the patient and affect behaviour, and which are resistant to current drug treatments. This project investigates dysfunctions in belief mechanisms that allow delusions to form and be maintained. This will help clinicians design more effective programs of cognitive behavioural therapy for psychosis by allowing more focussed interventions to reduce delusions.
Are Healthcare Interventions Exacerbating Alzheimer's Disease (AHEAD)

Summary
The AHEAD Study will assess the impact of anaesthesia and surgery on cognitive function in patients with Mild Cognitive Impairment or mild Alzheimer's Disease. Such effects have not been established. With an ageing population being increasingly exposed to healthcare procedures requiring anaesthesia or sedation, any negative impact needs to be identified so that therapeutic decisions may be informed and future research appropriately targeted.
This project examines the types of computations used by brain cells to combine two types of sensory information, in a way that allow us to reach better decisions in everyday life. To address this general problem, we will perform experiments that explore the combination of signals from vision and hearing. The ability to combine sensory information is vital to our mental health, and this process is compromised in a range of psychological, psychiatric and neurological disorders.
The Tasmanian Healthy Brain Project: A Longitudinal Intervention Study To Reduce The Risk Of Ageing-related Cognitive Decline And Dementia

Summary
It has been proposed that engagement in purposeful complex mental stimulation provides protection against dementia. The Tasmanian Healthy Brain Project (THBP) is a unique, large-scale prospective trial that examines whether university-level study in older adult population reduces ageing-related cognitive decline and risk of dementia. This project will also examine how an individual’s genetic profile may influence the potential benefits of complex mental stimulation as well as risk of dementia.
Novel Pharmacological Strategies To Treat Cognitive Dysfunction In COPD

Summary
Chronic Obstructive Pulmonary Disease (COPD) is a major incurable global health burden and is the 4th largest cause of death worldwide. Up to 60% of COPD patients suffer from cognitive dysfunction (i.e. a brain disorder which affects learning, memory, attention) which often leads to dementia. The reason for this is unknown so the aim of this study is to determine why people with COPD suffer from mental disorders then develop novel treatments to treat these disorders in COPD patients.
‘Granny was never the same after her operation’ is a strong public perception. These reports of persistent memory and concentration loss following surgery are now supported by a body of scientific research recording an incidence of ‘postoperative cognitive decline’ (POCD) as high as 75% in cardiac surgery patients. At present the cause is unknown but recently anaesthesia has been implicated. Our research team will investigate these claims.
Cognitive Control And Brain Connectivity Disturbances In Schizophrenia And Obsessive-compulsive: Clarifying Their Nature, Specificity, And Consequences

Summary
Deficits of behavioural control are chronic and debilitating features of both schizophrenia and OCD. As behavioural control depends on activity within many key regions of the brain, these deficits may result not only from dysfunction within one or more region, but also from abnormal interactions between them. By studying how the activity in one region depends on another, and comparing findings between disorders, a better understanding of brain function in schizophrenia and OCD can be established
Insights Into The Epitranscriptome: Linking RNA Methylation And Intellectual Disability

Funding Amount
$426,878.00
Summary
The string of nucleotides in an RNA molecule can contain the information to make proteins or to regulate diverse biological processes. Chemical modifications can be added to certain nucleotides that impact the regulation, structure or function of RNA. Recently, mutations in enzymes that modify RNA have been found in patients with intellectual disability. This project focuses on identifying and characterising specific RNA modification sites in brain that when disrupted cause mental retardation.
Investigating The Mechanisms That Increase Nerve-evoked Vasoconstriction Following Spinal Cord Injury

Funding Amount
$372,547.00
Summary
People with spinal cord injury not only lose control of their arms and legs but also lose control of their bladder and bowel. They also have poor control of blood pressure and an overfull bladder or bowel can lead to dangerously high blood pressure. In this project, we are investigating how this abnormal high blood pressure is generated. The aim is to develop treatments which target the mechanisms which increase the blood pressure responses elicited by the bladder and bowel.
