Early Indicators Of Noise Injury: Are Decreased Auditory Processing Skills Evident In Noise-exposed Adults Prior To Diagnosis Of Hearing Loss?

Funding Amount
$367,605.00
Summary
Recent research indicates that noise-exposed individuals with similar hearing thresholds to non-noise exposed counterparts are more likely to have diminished temporal and spectral auditory processing abilities. This research aims to determine the relationship between noise exposure levels and auditory processing difficulties; the influence of musical training in ameliorating these difficulties; and a neurological model of causation, operation and possible remediation of these difficulties.
Organization Of Descending Auditory Projections From Inferior Colliculus To Cochlear Nucleus

Summary
Sensory information gains awareness by ascending brain pathways to reach consciousness. Descending projections, however, have grown in importance because of implications for feedback management of ascending signals. Studies of these pathways will provide insight into auditory processing with respect to selective volume control, calibration adjustments between the two ears, and the extraction of signals from background noise. The data could lead to new strategies for treating hearing disorders.
Studies Of The Effects Of Asymmetric Hearing Loss On The Brain

Summary
Hearing loss impairs the normal development and maintenance of auditory pathways. Irreversible pathologies persist when hearing is not restored in a timely manner. While cochlear implantation is the accepted treatment for profound sensorineural hearing loss, there is significant variability in outcomes. Some of this variability is linked to the degree of hearing asymmetry. Thus, we propose to study brain changes in the auditory system that accompany asymmetric hearing impairment.
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.
Transdermal Testosterone Therapy: A Potential Treatment For Selective Serotonin Reuptake Inhibitor (SSRI)-associated Sexual Dysfunction In Women

Summary
Female sexual dysfunction (FSD) is frequently reported with selective serotonin reuptake inhibitor (SSRI) therapy and venlafaxine, these being the most common antidepressants used by Australian women. We have shown that testosterone therapy significantly improves sexual function in women with FSD. However SSRI-users have been excluded from these past studies. The aim of this study is to assess the efficacy of transdermal testosterone therapy for treatment of sexual dysfunction associated with SS ....Female sexual dysfunction (FSD) is frequently reported with selective serotonin reuptake inhibitor (SSRI) therapy and venlafaxine, these being the most common antidepressants used by Australian women.

Predicting Language Skills From Early Auditory Speech Discrimination In Infants With Hearing Loss: Implications For Early Management And Intervention

Funding Amount
$706,113.00
Summary
Now that newborn hearing checks are available, hearing loss can be picked up soon after birth and hearing aids are fitted shortly after. Although procedures exist for checking that the devices make sounds audible, there is no way to evaluate their effectiveness for supporting a child’s auditory discrimination. This study aims to 1) develop new clinical tools for assessing infants’ auditory discrimination, and 2) determine whether early discrimination predicts spoken language at 3 years of age.
Development Of The Listening In Spatialized Noise - Tonal Test (or LiSN-T)

Funding Amount
$227,136.00
Summary
In this project a novel listening test software will be developed for diagnosing spatial processing disorder in children. These children often have difficulties in understanding teachers in classrooms, which can significantly impact their ability to learn. The developed software will be specifically designed for diagnosing 5-year old children, before they enter primary school, and in contrast to existing tests will be independent of their language background.

Summary
Cardiovascular disease (CVD) claims 1 person every 10 min in Australia and causes 1 in 3 deaths worldwide. The molecular and cellular processes underlying atherosclerosis, vascular injury and thrombosis are highly complex and not well understood. A multifaceted approach is needed to effectively address these key challenges. This Program brings together world experts in these areas to interrogate gaps in our basic understanding of CVD, and to develop novel therapies for CVD patients by exploiting ....Cardiovascular disease (CVD) claims 1 person every 10 min in Australia and causes 1 in 3 deaths worldwide.

Identifying Neuroimaging Based Biomarkers For Predicting Clinical Progression Along The Lewy Body Disease Spectrum

Summary
Lewy body dementias (LBD) comprise similar but heterogenous group of poorly understood disabling neurodegenerative conditions. This project aims to apply advanced neuroimaging techniques and novel psychological testing to patients at risk of Lewy body disorders as well individuals with established disease to identify novel biomarkers that may explain symptoms of these disorders as well as help predict development of LBD at its early stages when it may be amenable to neuroprotective treatments.
