Summary
Schizophrenia is a serious mental illness that affects approximately 1% of the Australian population. The cause of the illness remains unknown but many lines of evidence suggest that changes in the function of a chemical neurotransmitter, serotonin, are involved in the disease process. We have shown a change in the serotonin transporter, a critical component of the brain which controls the actions of serotonin, in the an area of the brain called the hippocampus in subjects with schizophrenia.

The cause of the illness remains unknown but many lines of evidence suggest that changes in the function of a chemical neurotransmitter, serotonin, are involved in the disease process. We have shown a change in the serotonin transporter, a critical component of the brain which controls the actions of serotonin, in the an area of the brain called the hippocampus in subjects with schizophrenia. This proposal seeks to elucidate the mechanisms by which a change in the serotonin transporter may affect other important molecules in the hippocampus. In addition, we will continue our research designed to assess the usefulness of the 5,7-dihydroxytryptamine treated rat as a possible tool for the study of changes in the serotonin transporter.Read moreRead less
Investigating The Action Of Clozapine On The Epidermal Growth Factor System: Implications For Antipsychotic Drug Action

Summary
Current treatments for schizophrenia are ineffective for up to half of sufferers leaving the toxic drug clozapine as the only resort. This project aims to investigate if the unique effectiveness of clozapine is due to a novel action in brain cells that we have identified. The project will delineate this mechanism and from this may lead to the development of a new way of treating schizophrenia and insights into the causes of this disorder.
Competence To Give Informed Consent For Research Participation In Schizophrenia And Related Psychoses.

Summary
There is current controversy surrounding the ethics of allowing people with mental illness to participate in research. By trying to safe guard what is considered a vulnerable group, we may also be denying these people their rights to make decisions for themselves. The potential benefits of clinical research in an area where treatments are often ineffective and cause serious side effects may also be denied to these people. This study aims to measure the capacities of patients with psychoses to gi ....There is current controversy surrounding the ethics of allowing people with mental illness to participate in research. By trying to safe guard what is considered a vulnerable group, we may also be denying these people their rights to make decisions for themselves. The potential benefits of clinical research in an area where treatments are often ineffective and cause serious side effects may also be denied to these people. This study aims to measure the capacities of patients with psychoses to give informed consent to participate in clinical research. The uniqueness of this project is that subjects will be rated as either competent or incompetent according to legal definitions applicable in Australia by utilising predetermined thresholds. We will also determine whether performance of patients in tests of competence can be improved through an established educational program. Additionally we plan to re-evaluate patients after a period of 6 months in order to test the reliability of competence performance.Read moreRead less
