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
Autism and its milder forms affect approximately 6 per 1,000 children. The biological basis of the disorder is unknown, so considerable research is being invested in identifying cognitive processes that are atypical in children with autism because this may help identify key areas of the brain affected by the disorder. This research has established that children with autism often outperform their typically developing peers on tasks that require detailed analysis of visual information. In contrast ....Autism and its milder forms affect approximately 6 per 1,000 children. The biological basis of the disorder is unknown, so considerable research is being invested in identifying cognitive processes that are atypical in children with autism because this may help identify key areas of the brain affected by the disorder. This research has established that children with autism often outperform their typically developing peers on tasks that require detailed analysis of visual information. In contrast, visual tasks that require integrating information often reveal impaired performance in children with autism. Human vision is achieved through two pathways in the brain - a dorsal pathway most responsive to changing (e.g. moving or flickering) stimuli and a ventral pathway most responsive to enduring stimulus features (e.g. colour, pattern). Increasingly complex visual processing is achieved at higher levels in each pathway through integrating information from lower levels. One objective of our work is to identify which levels of processing in each of the dorsal and ventral pathways show atypical functioning (either enhanced or impaired) in autism. We will do this using tasks designed to establish thresholds for different perceptual judgements, such as identifying patterns in a field of dots. Children with autism will be compared to typically developing children and also to children with Specific Language Impairment (SLI). This will enable us to establish whether the same profile of strengths and weaknesses in perception and cognition are observed in autism and SLI, or whether they can be distinguished on this basis. The significance of the work is that it will advance considerably the understanding of atypical visual processing in autism and SLI. Also, by identifying perceptual and cognitive differences in children with autism, we may be able to develop tests to identify infants affected by the disorder and commence remediation at an early age.Read moreRead less

Summary
Despite advances in the treatment of RA, the condition continues to have a chronic course for the majority of patients. Research has established that the way in which people think about pain and illness influences their responses to symptoms. In turn, these factors can impinge on quality of life and disability. For people with chronic pain problems, those who are fearful of pain and concentrate on symptoms have a poorer outcome in the long-term.

Research has established that the way in which people think about pain and illness influences their responses to symptoms. In turn, these factors can impinge on quality of life and disability. For people with chronic pain problems, those who are fearful of pain and concentrate on symptoms have a poorer outcome in the long-term. In RA, striking a balance between rest and exercise is thought to be crucial. As such, ignoring the pain can lead to overactivity and subsequent joint damage and may be as unhelpful as underactivity. This project aims to investigate the relationship between people's fear of pain and the degree to which they attend to pain. It is suggested that those with very high or very low levels of fear towards the pain will either over-attend or under-attend to pain in comparison to healthy controls and patients with a moderate level of fear. Optimum levels of fear avoidance are expected to be associated with less disability and improved joint function. These findings have implications for the management of RA. Psychological treatments for patients with RA have been found to be effective in reducing pain, disability and improving mood. Treatments usually focus on a combination of changing people's attitudes and behaviours. However, whether strategies that aim to change attitudes or those targeting behaviour are more successful or have specific treatment effects is unknown. The present project will compare a treatment targeting behaviours associated with RA and encouraging a balanace between rest and exercise, with a treatment targeting patient's beliefs about the illness. It is expected that the treatments will have specific effects, which may better allow tailoring of psychological management to patient's individual needs.Read moreRead less

Summary
G proteins are molecular switches in all organisms, turning fundamental processes on and off . Defects in the functions of these switches can lead to severe diseases, such as cancer. Crucial details regarding the mechanism by which these switches are turned to on are still missing. This proposal will use a bacterial model system, with aims to provide structural and functional detail on the molecular mechanism of the switch in G proteins, and to extend this model to mammalian systems.
Mechanisms Of Immune Complex-mediated Inflammation In The Cerebral Microvasculature

Summary
Immune complexes are formed when an antibody binds to the molecules it is directed against. Normally, this is important for fighting infection. However in some autoimmune diseases, inappropriate formation of immune complexes can be damaging to our own tissues. This damage occurs because immune complexes attract white blood cells to the areas where they form. Many tissues can be affected by this process. However, we know very little about the effects of immune complexes specifically in the brain. ....Immune complexes are formed when an antibody binds to the molecules it is directed against.

However, we know very little about the effects of immune complexes specifically in the brain. This is important because immune complexes are found in the brain in diseases such as lupus. Therefore the aim of this proposal is to determine how immune complexes induce damaging inflammation in the brain.Read moreRead less
