Summary
Schizophrenia is a severe psychiatric disorder that affects approximately 1% of the population. This project will help define changes in the molecules in the brain of subjects with schizophrenia which are likely to be involved in two symptoms of the disorder, the psychoses and cognitive deficits. Understanding the cause of the cognitive deficits of schizophrenia is a high priority because they are the most disabilitating symptom of the disorder and do not respond to current drug treatments.
I am a consultant psychiatrist and clinical researcher. Over the last 15 years I have been trying to detect people at risk of development of schizophrenia and other psychotic disorders by the prospective identification of the prodromal phase of these diso
Gene - Environment Interactions As Predictors Of Clinical Outcome In At Risk Mental State

Summary
The grant aims to identify the interactive genetic, clinical and environmental determinants involved in the development, severity and outcome of schizophrenia. Translation to clinical practice will be facilitated by experimental and risk assessment bioinformatics research. This will enable the (i) identification of modifiable biological and cognitive mechanisms and (ii) construction of tools which can be used for the early prediction of transition to psychotic disorder and outcome monitoring.

Translation to clinical practice will be facilitated by experimental and risk assessment bioinformatics research. This will enable the (i) identification of modifiable biological and cognitive mechanisms and (ii) construction of tools which can be used for the early prediction of transition to psychotic disorder and outcome monitoring. This study will identify the factors that translate genetic vulnerability to schizophrenia into overt illness. The key risk factors of stress and substance use and other environmental features will be studied as part of randomised clinical trials in young people with early symptoms who are at immediate risk of schizophrenia. This study forms part of a much larger international program of research focusing on clarifying how the vulnerability to schizophrenia develops and how it can ultimately be preventedRead moreRead less
Neural Connectivity In Young People At High Risk Of Developing Psychosis

Summary
This project will investigate whether or not young people at high risk of developing psychosis show irregularities in the connections between different parts of their brain. It will also investigate whether information about a high-risk individual’s brain connectivity can be used to predict a) whether that person will make the transition to psychosis, and b) their clinical prognosis if they do become psychotic.
Understanding The Pathology Of Muscarinic Receptor Deficit Schizophrenia: A Biochemically Defined Form Of The Disorder.

Funding Amount
$451,804.00
Summary
Schizophrenia is a group of disorders with similar symptoms and no way of distinguishing the different disorders. In our brain collection 25% of the subjects with schizophrenia have a particular chemical deficit. Screening gene expression in people with schizophrenia, with and without this deficit will give a global picture of chemical differences between the groups. Understanding the differences between sub-groups of people with schizophrenia will aid the development of better drugs for them.
Outcome Prediction, Stratification And Novel Treatments In Individuals At Ultra High Risk Of Psychosis

Summary
The Ultra High Risk (UHR) criteria have been developed to identify people at high risk of psychotic disorders such as schizophrenia so that treatments can be provided early to reduce risk and disability. However the some UHR people are at risk of other difficulties and disorders and others are not at risk of all. We need to improve our ability to distinguish between these groups so that treatment can be tailored according to risk, and develop new treatments that target underlying problems.
It remains unclear what the causes of schizophrenia and other psychotic disorders are and what the most effective interventions are for preventing onset of disorder in those at risk. The current research program consists of a number of interrelated studies of how psychosis develops, the most effective sequential treatments to prevent the onset of disorder in high risk young people, and testing clinical criteria to identify young people at risk of a range of serious mental illnesses.
Antipsychotic Medication In First-episode Psychosis: An RCT To Assess The Risk-benefit Ratio

Summary
There has been an increasing emphasis on intervening early in psychotic disorders. A fundamental principle in early intervention is “to do no harm” and benefits must outweigh the risks of treatment. While antipsychotic medication is very effective and evidence-based form of treatment for positive symptoms in most first episode psychosis (FEP) patients it has risks. This study has the potential to determine whether antipsychotic medication should be the initial treatment option for FEP.
