Summary
More women develop Alzheimer's disease whereas more men develop Parkinson's disease. This study will try to understand whether sex hormones play a part in the devlopment of these diseases. This study will also try to answer how the female sex hormone, oestrogen, influences behaviour and or development of mental health problems such as depression and obsessive-compulsive disorder.

Summary
Obsessive-compulsive disorder (OCD) is a psychiatric disorder that affects up to 3% of the general population. People with the disorder experience unpleasant intrusive thoughts that they find distressing and have a strong urge to perform particular behaviours. Fears about fire and burglary are common and excessive checking of electrical appliances and locks can take many hours a day. Checkers represent one of the largest OCD sub-groups.

People with the disorder experience unpleasant intrusive thoughts that they find distressing and have a strong urge to perform particular behaviours. Fears about fire and burglary are common and excessive checking of electrical appliances and locks can take many hours a day. Checkers represent one of the largest OCD sub-groups. Because of the time-consuming nature of the condition, social and occupational functioning is often severely restricted. Many sufferers will also experience extreme social isolation and depression. The World Health Organisation ranks this disorder as 20th among all causes of burden of disease. The development of effective interventions could substantially reduce the economic and social burden of this disabling anxiety disorder. The aim of this project is: (1) to compare the therapeutic efficacy of a new treatment approach (Danger Ideation Reduction Therapy) with that of Exposure and Response Prevention (ERP); It is hypothesised that: (1) subjects who receive 12 sessions of DIRT will show greater post-treatment and follow-up reductions in symptomatology than subjects who receive ERP.Read moreRead less

Summary
Obsessive-compulsive disorder (OCD) in children is a severely debilitating mental health problem affecting between 0.5 and 1% of the population at any point in time. Children with OCD frequently experience high functional impairment as a result of their symptoms, including deteriorating school performance and poor peer relationships. Family life is often disrupted, causing significant distress and hardship to parents and siblings. However, little research attention has been paid to how families ....Obsessive-compulsive disorder (OCD) in children is a severely debilitating mental health problem affecting between 0.5 and 1% of the population at any point in time. Children with OCD frequently experience high functional impairment as a result of their symptoms, including deteriorating school performance and poor peer relationships. Family life is often disrupted, causing significant distress and hardship to parents and siblings. However, little research attention has been paid to how families affect and are affected by this disabling condition. This research examines the role of learning in the development, maintenance and treatment of OCD. Specifically, the study aims to: 1. explore the way in which children with OCD process threatening information 2. investigate the influence of parents on children's processing of OCD-relevant information 3. develop and implement the world's first randomised control trial of cognitive-behavioural plus parent training (CBT + PT) for childhood OCD 4. evaluate parent-assisted treatment in comparison to a standard cognitive-behavioural treatment (CBT) and a placebo control 5. examine the long-term maintenance of each type of treatment The outcomes of this project will be: 1. an improved understanding of OCD in children, and their families 2. an increased knowledge of the relationship between parenting processes and OCD symptomatology 3. the development and dissemination of an evidence-based treatment for childhood OCDRead moreRead less

Summary
Schizophrenia and obsessive-compulsive disorder (OCD) are extremely disabling psychiatric disorders. Both tend to appear in early adulthood and have a number of important similarities. These include problems with planning and organising thoughts, abnormal brain chemistry, and changed function in the same brain region, the anterior cingulate. The anterior cingulate has been known for some time to be involved in emotion, motivation and attention.

Both tend to appear in early adulthood and have a number of important similarities. These include problems with planning and organising thoughts, abnormal brain chemistry, and changed function in the same brain region, the anterior cingulate. The anterior cingulate has been known for some time to be involved in emotion, motivation and attention. However, it is now recognised as the interface between the emotional, feeling part of the brain and the controlling, thinking part. Many, if not all, of the functions performed by the anterior cingulate are disturbed in both schizophrenia and OCD, meaning that studying this region may provide important clues to the nature of the two illnesses. One important characteristic of the anterior cingulate which has not been considered in previous research is its division into three distinct subregions, each with their own specific function. In particular, there is a cognitive region, which deals with response selection and information processing, and an emotional region, which assesses motivational content and controls emotional learning. Because of the nature of the two disorders we intend to study, we believe that schizophrenia will be associated with more abnormalities of the cognitive region, while OCD will be associated with changes in the emotional region. Another important feature of our research design is that we intend to collect data from the same subjects using four separate brain imaging techniques, which provide information about different levels of brain structure and function. This will allow us to interpret our findings from measures of brain chemistry in the context of our findings of brain function. Hopefully this will help us to clarify the pathophysiology of schizophrenia and OCD, and provide potential ways to assess the effect of different treatment strategies in these illnesses.Read moreRead less
The Neurochemical Basis Of Behavioural Control: Relevance For Addiction, OCD And Tourette Syndrome.

Summary
Both the control of voluntry responses over reflexive habits, and the ability to direct voluntary responses appropriately when there are conflicting choices present in the world, are thought to be important in mental disorders such as drug addiction, tic disorders such as Tourette syndrome and obsessive compulsive disorder. This project will examine the brain neurochemistry that underpins our ability to control voluntary responses, providing insight into potential pharmacological interventions.
