Summary
Despite the alarming obesity epidemic, there currently exists no effective long-term treatment for obesity. Neuropeptide FF and its receptor NPFF2R have an emerging role in regulating food intake and body fat stores. Results from this study will show whether NPFF2R plays an important role in regulating appetite, metabolic rate, body weight and fat stores, thus help to identify whether NPFF2R-targeted therapeutics would confer significant benefit for the long-term treatment of obesity.
Hypothalamic Regulation Of Appetite And Energy Homeostasis In Prader-Willi Syndrome.

Summary
Prader-Willi syndrome (PWS) is a genetic disease affecting 1/~15 000 people. It causes insatiable appetite and often morbid obesity, as well as other developmental problems. It is thought that there is a defect in the way that the brain regulates eating behaviour in PWS, but the exact mechanism is still unknown. This study proposes to explore metabolic and genetic factors contributing to the appetite disorder in PWS. It will also explore new ways of treating excessive appetite.
Understanding The Brain In The Transition From Acute To Chronic Low Back Pain

Funding Amount
$107,049.00
Summary
A critical question in treating low back pain (LBP) is why some people get better after hurting their back while others do not. Physiological mechanisms, such as brain plasticity and central sensitisation, are believed to underpin the transition to persistent pain. This is the first study to evaluate these mechanisms longitudinally and their relationship with LBP outcomes. The result of this research will provide better understanding of pain mechanisms of LBP and assist to develop novel therapy.
Speech Impairment In Frontotemporal Dementia And Primary Progressive Aphasia

Funding Amount
$50,888.00
Summary
This research project aims to inform our understanding of the characteristics and trajectory of speech difficulties in frontotemporal dementia and primary progressive aphasia, two forms of younger onset dementia. Understanding the changes to speech that occur will assist with the early diagnosis of these disorders and improve measurement of disease progression. Findings will positively influence patient care through the identification of treatment targets and improved knowledge of prognosis.
The Neuro-ophthalmological Manifestations Of Human Mitochondrial Diseases.

Funding Amount
$100,675.00
Summary
Human mitochondrial diseases often result in neuro-ophthalmological abnormalities. We aim to examine a cohort of patients with mitochondrial disease and document the type and degree of neuro-ophthalmological abnormality. We will provide detail on the retina, optic nerve, oculomotor function, eyelids and visual acuity. We will examine the optic nerve in detail and perform optical coherence tomography and visual evoked potentials on each patient. We will compare results to age-matched controls.
Cognition In First Episode Psychosis: Mapping Relationships Between Task Performance, Brain Changes And Symptoms

Funding Amount
$79,734.00
Summary
Schizophrenia is a devastating illness. Medication can successfully treat the 'positive' symptoms, such as hallucinations and delusions. However, cognitive impairments have been identified as a greater burden. This project aims to better understand the brain basis of these cognitive impairments, by looking at the relationships between participants’ responses to cognitive tests, their brain activity during the testing, and their symptoms and general functioning over time.
Identifying Neuroanatomical Sub-phenotypes Of Schizophrenia

Funding Amount
$60,129.00
Summary
The clinical presentation of schizophrenia is varied across individuals, and has arguably hindered efforts to determine its cause/s. This project seeks to address this issue by investigating biological commonality in patients, to identify subgroups of schizophrenia patients with similar brain abnormalities, with the overall aim to examine cognitive and clinical characteristics and candidate genetic markers in association with biologically derived subtypes of schizophrenia.
Obesity Hypoventilation Syndrome And Neurocognitive Dysfunction
Funder

Funding Amount
$124,608.00
Summary
In this study, we will assess neurocognitive function in patients with obesity hypoventilation syndrome (OHS – too slow or too shallow breathing) using a battery of tests including driving simulation, before and after 3 months of positive airway pressure therapy (CPAP). This will assess if chronically raised carbon dioxide levels contribute to impaired thinking capacity in addition to low oxygen levels.
