Summary
It is now widely accepted that schizophrenia is associated with changes in the structure of the brain. Until recently these structural changes were considered to predate the onset of illness and to remain static. However, our own work has suggested an alternative model, which relates schizophrenia to brain changes at specific life stages. In order to demonstrate this, we intend to acquire repeat brain images on 100 patients who were initially scanned 10 years ago at the start of their psychotic ....It is now widely accepted that schizophrenia is associated with changes in the structure of the brain. Until recently these structural changes were considered to predate the onset of illness and to remain static. However, our own work has suggested an alternative model, which relates schizophrenia to brain changes at specific life stages. In order to demonstrate this, we intend to acquire repeat brain images on 100 patients who were initially scanned 10 years ago at the start of their psychotic illness. This would be the largest follow-up study of first episode psychosis in the world, with the longest interval between the first and second brain scan. Further, for a proportion of patients we will have 3 MRI scans, at illness onset, 2-4 years post-onset, followed by a third scan at 10 years, thereby providing unique follow-up brain imaging data. Based on our own and other research, we intend to explore the relationship between progressive brain change over a ten year period and: (i) the diagnosis of the patient (schizophrenia or other disorder), (ii) the clinical and functional outcome of the patient (still chronically ill or with no further episode of psychosis), and (iii) the cognitive state of the patient (their ability to perform well on tests of memory, planning and so on). We are able to conduct this study because of the existence of an infrastructure developed to follow-up patients, with a recontact rate of 70% of those patients admitted in 1992 and 1993. In this study we seek to implement these strategies for the patients identified after 1994. The results of this study will test our ideas derived from our model of the major psychotic illnesses and may identify the structural brain changes which are associated with the development of chronic schizophrenia and other psychoses. A further novel outcome will be the inclusion of patients who have remained well and identiifying the structural correlates of a good prognosis.Read moreRead less
A Parent Education And Skills Training Intervention For Young Adolescents With Autism

Summary
Autism is a most severe and prevalent lifelong developmental disorder affecting approximately one in every thousand children and their families. Autism is associated with personal suffering and is a significant burden and stress for parents, families and carers and cost to the community. In earlier work we have demonstrated that providing a structured program of parent education and guidance to families with preschool children with autism leads to improved parental adjustment and mental health. ....Autism is a most severe and prevalent lifelong developmental disorder affecting approximately one in every thousand children and their families. Autism is associated with personal suffering and is a significant burden and stress for parents, families and carers and cost to the community. In earlier work we have demonstrated that providing a structured program of parent education and guidance to families with preschool children with autism leads to improved parental adjustment and mental health. The program also led to behavioural and developmental benefits for the child. The early secondary school years bring further stress and difficulty to adolescents with autism and their families. This project aims to assess the effectiveness of a parent education and training program for parents with autistic adolescents aged 12-14 years. If shown to be effective, this manual based intervention can be readily used by professionals to promote parent mental health, family adjustment and improve the wellbeing and outcome for adolescents with autism. As a result, family stress and the necessity of out of home care may be reduced and school participation improved.Read moreRead less
