Summary
This Project will apply new, fast, safe, comprehensive, balance tests we have developed to measure the function of the balance receptors of the inner ear. We will track changes in balance function during disease and recovery in the many, and increasing, number of Australian patients with balance disorders. These tests will give us insight into changes in the inner ear associated with severe attacks of vertigo and why some patients recover so poorly after damage to inner ear balance receptors.
Acute Vertigo In Emergency Departments: Distinguishing Between Central And Peripheral Causes By Objective Measure Of Oculomotor Examination (HINTS)

Funding Amount
$181,065.00
Summary
The goal of this work is to provide a quantitative objective measure of HINTS for developing an automatic diagnostic decision tool to differentiate vestibular neuritis (peripheral) and stroke (central) in patients presenting in emergency department for acute vestibular syndrome. Video oculography makes interpretation of the results more reliable. Video oculography goggles will be used as part of a systematic training program to enhance frontline clinician skills in eye movement examination.
Investigating Caloric Vestibular Stimulation As A Novel Therapeutic Intervention For Chronic Pain, Mania And Depression.

Summary
Chronic pain, mania and depression are common health problems worldwide and represent an enormous burden of illness. Current treatments may be costly, invasive and have serious side-effects. In the proposed project, demonstration of therapeutic benefit with a novel, simple method of brain stimulation without such limitations could change how these disorders are managed. Moreover, the findings would be of substantial significance in developing countries where treatments are often non-existent.

Summary
The obstructive sleep apnoea hypopnoea syndrome (OSAHS) refers to a condition in which throat blockage occurs during sleep leading to breathing difficulties, including snoring and cessation of breathing for short periods of time. OSAHS is amongst the commonest of chronic disorders of adult males, occuring in 5% of men over the age of 45 years. It is now recognised that one of the major complications of OSAHS is the development of high blood pressure and heart disease.

OSAHS is amongst the commonest of chronic disorders of adult males, occuring in 5% of men over the age of 45 years. It is now recognised that one of the major complications of OSAHS is the development of high blood pressure and heart disease. In the proposed studies, we will examine the proposal that snoring alone, without significant associated OSAHS, can also lead to high blood pressure in habitual snorers both awake and asleep. In particular, we will explore the hypothesis that chronic snoring transmits a pressure wave through the tissues of the neck to the carotid artery which is the main blood supply to the brain. We propose that the chronic vibration of this artery can alter pressure sensors in the artery wall, which then results in the persistance of high blood pressure. Our studies will help to prove that this is a mechanism whereby both snoring and OSAHS may contribute to the development of high blood pressure. The recognition of snoring as an independent risk factor for high blood pressure will clearly have important and wide ranging implications for the future management of snoring in the prevention of high blood pressure.Read moreRead less
Glucose is a critical fuel for living organisms and its presence in the gut triggers nerves that slow stomach emptying. However, little is known of how glucose is actually detected in the gut. We have established that sweet taste molecules of the tongue are also present in the gut, where they may detect glucose. This research will measure the expression and function of these molecules in the gut of humans and mice, and reveal key information on their potential as targets in health and disease.
