Summary
Bipolar disorder (manic depressive illness) is a severe mood disorder, with a lifetime prevalence of up to 1%. The illness is characterised by aberrant mood swings resulting in periods of mania and depression with reversion to normal behaviour between episodes. The condition has a severe impact on sufferers, being demonstrated to be the sixth most disabling disorder in the WHO Global Burden of Disease report and increasing the risk of suicide fifteen-fold. There is a pressing need to define more ....Bipolar disorder (manic depressive illness) is a severe mood disorder, with a lifetime prevalence of up to 1%. The illness is characterised by aberrant mood swings resulting in periods of mania and depression with reversion to normal behaviour between episodes. The condition has a severe impact on sufferers, being demonstrated to be the sixth most disabling disorder in the WHO Global Burden of Disease report and increasing the risk of suicide fifteen-fold. There is a pressing need to define more clearly the biological basis of bipolar disorder as a necessary prerequisite to improved diagnosis and treatment. The underlying causes of bipolar disorder remain unknown. However, family studies reveal the high heritability of bipolar disorder and this familial clustering provides an opportunity to use genetic approaches to identify the predisposing genes. The long-term aim of our research is to investigate the biology of those genes that either cause or predispose to bipolar disorder. We have previously used genetic approaches to identify the first bipolar disorder susceptibility gene, a cell contact molecule located on chromosome 4 that is from the cadherin family. The aim of this proposal is to understand how this gene contributes to the risk of developing bipolar disorder. This will be achieved by identifying how the cadherin susceptibility gene, termed 'FAT' results in altered properties in laboratory assays or in altered behaviours in animal models. Identifying the genes responsible for bipolar disorder and understanding their contribution to the biological basis of this severe psychiatric condition is essential to translate these discoveries into improvements in the ability to diagnose, treat and prevent the illness.Read moreRead less
Cloning And Characterisation Of A Bipolar Disorder Susceptibility Gene On Chromosome 15q

Summary
Bipolar disorder is a severe mood disorder, characterised by aberrant mood swings resulting in periods of mania and depression. We need to define more clearly the biological basis of bipolar disorder to improve diagnosis and treatment. Bipolar disorder is highly heritabile allowing the use of genetics to identify the predisposing genes. Our aim is to identify a bipolar susceptibility gene on chromosome 15 and to understand how this gene contributes to the risk of developing bipolar disorder.
Psychiatric disorders are associated with considerable social and economic burden which could be reduced if we understood mental health outcomes in high risk populations. This fellowship will use advanced brain imaging to understand the development of mental health disorders in those at high risk of bipolar disorder and dementia.
Kava For The Treatment Of Generalized Anxiety Disorder: A 16-Week Double-Blind RCT

Summary
Herbal medicines play a prominent role in traditional medicine to treat affective disorders (mood and anxiety disorders), however scientific studies are needed to truly assess their effectiveness. This clinical trial is examining the anxiolytic efficacy of Kava in treating chronic anxiety. As current response to antidepressant drugs can be inadequate, Kava may offer an additional affordable, safe, and effective option to reduce anxiety.
The Efficacy Of Adjunctive Garcinia Mangostana Linn. Pericarp For Bipolar Depression: A 24-week Double-blind, Randomized, Placebo-controlled Trial.

Summary
Bipolar disorder, especially during episodes of depression, can be highly debilitating. There is scientific evidence now directing research towards new targets to produce new therapies for bipolar depression. The current study aims to utilise an entirely new agent made from the husk of the mangosteen fruit (mangosteen pericarp). Mangosteen pericarp has properties that we believe will assist in reducing symptoms for those with bipolar depression, when taken in addition to usual treatment.
