The recent decade has been characterized by a resurging interest for socio-environmental determinants of psychotic disorders, largely as a result of findings from studies of migration and psychotic disorders. This contribution reviews recent meta-analytic findings which confirm higher incidence rates of schizophrenia and related disorders among first- and second-generation immigrants than in nonimmigrant population Read More

Stress plays a role in most conceptualizations of the etiology of psychotic disorders. This is based on extensive research showing an association between the incidence of psychosis and psychosocial stress exposure (e.g., stressful life events and trauma) both in childhood and the weeks preceding a psychotic episode. There is also evidence of increased sensitivity to stressful events and dysregulation of biological stress sy Read More

Background: The aim of cognitive remediation is to target the cognitive impairments of patients with psychosis, including attentional deficits, memory problems, and limitations in planning and problem solving. It is hoped that by addressing these deficits, patients will be more able to take advantage of other interventions and will be more able to function in social and other domains. Many results in controlled trials of cognit Read More

Cannabis is the most widely used illicit substance in the world and due to the high levels of use observed among young people with psychosis, most research has focused on the causal relationship between cannabis use and mental health problems. Despite a large interest in developing intervention models to target this group, there are as yet no established and effective methods of prevention and intervention focusing Read More

Over the last couple of decades, the treatment of psychoses has much advanced; yet, despite all progress, the individual and societal burden associated with psychosis and particularly schizophrenia has largely remained unchanged. Therefore, much hope is currently placed on indicated prevention as a mean to fight these burdens before they set in. Though the number of studies investigating pharmacological interventio Read More

There is a strong impetus in the psychosis research field to develop interventions that aim to prevent the onset of psychotic disorders. Over the past 15 years there has been a tremendous development in the work aimed at understanding the pre-psychotic period. More recently there has been a focus on developing and testing treatments both pharmacological and psychological that could potentially prevent or delay the o Read More

Pychoeducation is a useful and required intervention in subjects with elevated-risk state of psychosis. Psychoeducation is, however, an under-investigated area in the field of early identification and prevention. Psychoeducation with this particular patient group needs to adapt to several unique features, e.g. the diagnostic uncertainty (“say it only in subjunctive”) and problems of stigmatization. More research regarding th Read More

Objectives: To investigate if low-dose lithium may counteract the microstructural and metabolic brain changes proposed to occur in individuals at ultra-high risk (UHR) for psychosis. Methods: Hippocampal T2 relaxation time (HT2RT) and proton magnetic resonance spectroscopy (1H-MRS) measurements were performed prior to initiation and following three months of treatment in 11 UHR patients receiving low-dose lithium Read More

The role of polyunsaturated fatty acids and their metabolites for the cause and treatment of psychotic disorders are widely discussed. The efficacy as an augmenting agent in chronic schizophrenia seems to be small or not present, however epidemiological data, as well as some recent controlled studies in emerging psychosis point towards possible preventive effects of long-chain polyunsaturated fatty acids in early and Read More

Background: Whilst there is a growing body of evidence relating to the effectiveness of early detection and early intervention services there have been relatively few studies which have provided information on whether they are cost-effective. Aim: The aim of this paper is to review the cost-effectiveness evidence for early detection and early intervention in psychosis. Methods: Full economic evaluations, cost studies, and stud Read More

In this paper we try to examine some of the philosophical issues that arise from the clinical and scientific study of the prodromal phase of psychotic illness. These issues can be broadly grouped in to ethical concerns and those relating to the philosophy of psychology and science. Specifically, we discuss the notion of the prodrome as a discrete disorder as opposed to being a segment of the continuum of psychosis, and whether w Read More

The last 15 years have witnessed a shift in schizophrenia research with increasing interest in earlier stages of illness with the hope of early intervention and ultimately prevention of psychotic illness. Large-scale longitudinal studies have identified clinical and biological risk factors associated with increased risk of psychotic conversion, which together with symptomatic and demographic risk factors may improve the Read More
