Summary
The project aims to test the efficacy of two treatments to determine whether 'integrated' psychological treatment leads to better outcomes for those individuals presenting for treatment for the first time. Neuroleptic medication is the main treatment for the positive symptoms (i.e., delusions, hallucinations and thought disorder) which typify the psychoses, including schizophrenia. Yet, there are reasons why other approaches should be investigated.

Neuroleptic medication is the main treatment for the positive symptoms (i.e., delusions, hallucinations and thought disorder) which typify the psychoses, including schizophrenia. Yet, there are reasons why other approaches should be investigated. Firstly, not all patients respond to medications. Secondly, medication may not totally alleviate the positive symptoms, and thirdly, other aspects of the condition are not helped to any extent by medication. These aspects include negative symptoms (e.g., lack of motivation and asociality), depression, social anxiety and functioning in the various life domains, e.g., school, work and socialization. In the last 15 years a viable psychological treatment known as cognitive-behavioural therapy (CBT) has emerged. This appears to be effective in the treatment of hallucinations and delusions and has an effect over and above that produced by medication. However, such treatments have not yet been applied to treating those symptoms in first presentation psychotic patients when they are in the acute stage of their illness. It is important to determine whether CBT produces positive effects in this group and whether used in conjunction with medication it can produce greater and more rapid reductions in the level and severity of positive symptoms. Whilst CBT is expected to produce positive changes in delusions and hallucinations, the applicants believe this needs to be integrated with CBT interevention focussed on other aspects of a patient's presentation, such as negative and depressive symptoms, and also on improving functioning in various life domains.Read moreRead less
A Prospective Study Investigating Implications Of Bioactive Lipids For Diagnosis And Treatment Of Schizophrenia

Summary
This study will investigate the role of fatty acids (lipids) in schizophrenia. Studies in blood cells and in the brains of patients with schizophrenia have shown that these lipids and related products are altered in schizophrenia. We are now able to measure separate lipid metabolites in the living human brain using a technique called magnetic resonance spectroscopy. Until recently it was only possible to assess lipid metabolites as a group, limiting interpretation.

Studies in blood cells and in the brains of patients with schizophrenia have shown that these lipids and related products are altered in schizophrenia. We are now able to measure separate lipid metabolites in the living human brain using a technique called magnetic resonance spectroscopy. Until recently it was only possible to assess lipid metabolites as a group, limiting interpretation. Thanks to a newly available imaging system at the Brain Imaging Research Institute and a new analysis technique, we will be able to measure single lipid metabolites in the living human brain. Simultaneously we will also measure lipids and related enzymes in red blood cells that are responsible for the regulation of these lipids. Preliminary data has shown that there is a strong correlation between these two measures. Furthermore we will investigate the genes that are responsible for the production of these enzymes. By repeating the same tests after 12 weeks we hope to understand how the newer antipsychotic drugs act. Two easy clinical tests (a skin and breath test) will help us to implement the findings in daily clinical practice (diagnostic markers for patients at risk) . With such a multi-level approach we hope to contribute to a new understanding of the origins of schizophrenia going beyond the traditional concepts. The findings might also have direct implications for treatment. Preliminary results are very promising but also contradictory. Therefore it is even more important to carefully investigate the role of these lipids in schizophrenia.Read moreRead less
