Summary
Electroconvulsive therapy (ECT) is a highly effective treatment for depression, used in Australia and throughout the world to treat severe depression that has not responded to other treatments. Despite clear evidence of its effectiveness as a treatment, the use of ECT is limited by concerns over memory side effects. This study evaluates a new approach to ECT that has the potential to preserve its effectiveness, while greatly reducing effects on memory.

Summary
Prostate cancer affects thousands of men each year. Advances in treatment are continuing, but side-effects frequently create disruptions to daily living. If the quality of care for prostate cancer patients is to be further improved, there is much to be learned about the psychosocial impact of the disease and its treatment across its different phases. There has not been a systematic prospective study of psychosocial adjustment in men with prostate cancer.

If the quality of care for prostate cancer patients is to be further improved, there is much to be learned about the psychosocial impact of the disease and its treatment across its different phases. There has not been a systematic prospective study of psychosocial adjustment in men with prostate cancer. In this study, we longitudinally follow two separate groups of men with prostate cancer, those with early disease and those with advanced illness. We focus on the particular side-effects of urinary incontinence, impotence and bowel symptoms and the potential these have to affect the patient's sense of wellbeing. We use a standardised interview and questionnaires to assess for the presence of psychiatric disorders and psychological problems, overall quality of life and coping styles in these men. We seek to recognise the predictors of men who may have coping problems. A statistical approach termed pathway analysis will help us understand the relative contributions of different factors associated with these problems. The outcome of this systematic, longitudinal study will be a body of knowledge concerning risk factors for poorer psychosocial adjustment and optimum coping strategies for managing the impact of prostate cancer and its treatment, thereby empowering a range of targeted interventions to be developed to enhance the wellbeing and quality of life of these men.Read moreRead less
Attentional Effects On Prepulse Inhibition Of The Acoustic Startle Reflex In Patients With Schizophrenia

Summary
People suffering from schizophrenia exhibit differences from healthy people in the startle reflex, which is a blink of the eyes when a sudden loud sound occurs. Normally, this reflex is reduced in size when a quiet sound occurs a few milliseconds before the startling sound, but this prepulse inhibition of the startle reflex or PPI does not occur to the same degree in people with schizophrenia. The underlying causes of this reduction in PPI in patients with schizophrenia is not known. The most co ....People suffering from schizophrenia exhibit differences from healthy people in the startle reflex, which is a blink of the eyes when a sudden loud sound occurs. Normally, this reflex is reduced in size when a quiet sound occurs a few milliseconds before the startling sound, but this prepulse inhibition of the startle reflex or PPI does not occur to the same degree in people with schizophrenia. The underlying causes of this reduction in PPI in patients with schizophrenia is not known. The most commonly accepted theory is that it reflects a deficit in a basic sensorimotor gating function which could underlie a variety of attentional abnormalities observed in schizophrenia. However, our data indicate that patients exhibit more PPI when they ignore the prepulse stimuli. We wish to test the hypothesis that alterations in PPI in schizophrenic patients are secondary to abnormalities in attention. This is significant because the theory can point to a specific cognitive deficit associated with schizophrenia. We have also found that patients treated with some kinds of antipsychotic medications (the newer atypical antipsychotic medications) do not show reductions in PPI, but patients treated with older types of antipsychotic drug do show reductions in PPI. We intend to investigate the effects of different types of antipsychotics on attentional modulation of PPI. This is significant because it may indicate that patients with a specific kind of cognitive impairment may show improvement with a specific type of medicine. Our data suggests that chronic cannabis use may associated with differences in the startle reflex and in PPI. Understanding how such cannabis use alters PPI may provide insights into why so many people with schizophrenia regularly abuse cannabis.Read moreRead less
Depression And Risk Of Coronary Heart Disease: A Prospective Study Of Mediating Haemostatic Risk Factors

Summary
Growing evidence suggests that depression, anger and anxiety play a role in causing coronary heart disease (CHD) and complicating the outcome in existing CHD. This may occur by effects of these emotions on promoting blood clotting and the stickiness of platelets - the blood cells responsible for blood clotting. This pilot study will follow a group of people with depression but without CHD and a control group over 8 months to compare how the blood clotting profile changes as depression resolves. ....Growing evidence suggests that depression, anger and anxiety play a role in causing coronary heart disease (CHD) and complicating the outcome in existing CHD. This may occur by effects of these emotions on promoting blood clotting and the stickiness of platelets - the blood cells responsible for blood clotting. This pilot study will follow a group of people with depression but without CHD and a control group over 8 months to compare how the blood clotting profile changes as depression resolves. The potential benefits of this research are a better understanding of the links between the common illnesses of depression and CHD that might improve the prevention and treatment of heart disease.Read moreRead less
