Depression and Diabetes: Prevalence, diagnosis and help-seeking: Influence on depression, glycemic control and quality of life. Depression has been reported to be twice as prevalent and more persistent in individuals with diabetes than in the general population. The current research will investigate the point-prevalence of depression in a large sample of Australian diabetic outpatients using a case-finding instrument (CES-D) and follow-up structured clinical interview where appropriate. Demogr ....Depression and Diabetes: Prevalence, diagnosis and help-seeking: Influence on depression, glycemic control and quality of life. Depression has been reported to be twice as prevalent and more persistent in individuals with diabetes than in the general population. The current research will investigate the point-prevalence of depression in a large sample of Australian diabetic outpatients using a case-finding instrument (CES-D) and follow-up structured clinical interview where appropriate. Demographic, medical, and psychological correlates of depressiono will be investigated. The effects of the screening procedure and diagnosis on help-seeking behaviour, course of the depression, self-care, and glycemic control as well as qualtiy of life will be evaluated after six months.Read moreRead less
The articulate brain. Language is essential to human interaction, yet we know comparatively little about the mental processes involved and how they are represented in the brain, how genetic and environmental factors contribute to the development of language, or how effective treatments of language disorders work. The significance of this program of research lies in its capacity to enhance our understanding of a range of mechanisms responsible for a fundamentally human ability, and provide inform ....The articulate brain. Language is essential to human interaction, yet we know comparatively little about the mental processes involved and how they are represented in the brain, how genetic and environmental factors contribute to the development of language, or how effective treatments of language disorders work. The significance of this program of research lies in its capacity to enhance our understanding of a range of mechanisms responsible for a fundamentally human ability, and provide information that will ultimately inform clinical practice. In particular, new knowledge about the brain mechanisms involved in language processing and recovery will inform clinicians about the optimal choice of treatment to maximise outcomes for the individual patient.

How does dopamine modulate adult new word learning? Stroke is a chronic disease of increasing prevalence with increasing age. There is a critical need to develop more effective treatments of communication disorders in this population. One way of achieving this is to combine certain drugs with language therapy. Through studying how these drugs influence language, this research will provide vital knowledge for developing effective forms of pharmacotherapy for adults with language disorders after b ....How does dopamine modulate adult new word learning? Stroke is a chronic disease of increasing prevalence with increasing age. There is a critical need to develop more effective treatments of communication disorders in this population. One way of achieving this is to combine certain drugs with language therapy. Through studying how these drugs influence language, this research will provide vital knowledge for developing effective forms of pharmacotherapy for adults with language disorders after brain injury. More effective language rehabilitation can have direct positive consequences on the ability to regain and maintain employment and social relationships after stroke or brain injury and will address the large and growing social and economic cost to the nation.Read moreRead less
A functional imaging study of semantic processing modulated by dopamine. The role of dopamine in language processing is largely unknown, despite emerging evidence that dopaminergic alterations can modulate language in schizophrenia, Parkinson's disease, and healthy individuals. The research aims to reveal the neural and behavioural correlates of dopaminergic modulation of semantic processing using neuroimaging in healthy individuals who have ingested levodopa. It is hypothesised that levodopa wi ....A functional imaging study of semantic processing modulated by dopamine. The role of dopamine in language processing is largely unknown, despite emerging evidence that dopaminergic alterations can modulate language in schizophrenia, Parkinson's disease, and healthy individuals. The research aims to reveal the neural and behavioural correlates of dopaminergic modulation of semantic processing using neuroimaging in healthy individuals who have ingested levodopa. It is hypothesised that levodopa will modulate brain activity under circumstances where there is heightened semantic competition, consistent with a contemporary theory of dopaminergic cognitive control. The expected outcome of the research is an increased understanding of the interactions between dopamine, the language faculty, and associated neural systems.Read moreRead less
