Psychotic disorders are associated with neurobehavioral impairments in mental state attribution (mentalizing). These impairments are most severe in psychotic patients with elevated symptom levels, particularly negative and cognitive symptoms. There have been few studies of functional connectivity related to mentalizing in psychotic disorders and associations with symptoms. We conducted a functional MRI study of affective mentalizing in individuals with psychotic disorders and varying symptom levels (positive, negative, cognitive)...

OBJECTIVE: Social impairment is a long-recognized core feature of schizophrenia and is common in other psychotic disorders. Still, to date the long-term trajectories of social impairment in psychotic disorders have rarely been studied systematically. METHODS: Data came from the Suffolk County Mental Health Project, a 20-year prospective study of first-admission patients with psychotic disorders. A never-psychotic comparison group was also assessed. Latent class growth analysis was applied to longitudinal data on social functioning from 485 respondents with schizophrenia spectrum disorders and psychotic mood disorders, and associations of the empirically derived trajectories with premorbid social adjustment, diagnosis, and 20-year outcomes were examined...

Aims: To evaluate the effectiveness of evidence based treatments for alcohol-induced psychotic disorder (AIPD) as described by ICD-10 and DSM-5, a condition that is distinct from schizophrenia and has a close relationship with alcohol withdrawal states. Method: Systematic review using PRISMA guidelines. Results: Of 6205 abstracts found, fifteen studies and ten case reports met criteria and were examined. Larger studies examined the use of first-generation antipsychotic drugs, reporting full or partial remission in most patients...

Reported childhood abuse has been linked to the severity of clinical symptoms and social dysfunction in non-affective psychotic disorder. Impaired mentalizing ability may be one of the mechanisms accounting for this effect. This study examined whether impaired mentalizing mediates the effect of reported childhood abuse on positive symptoms, negative symptoms, and social dysfunction. Eighty-seven patients with non-affective psychotic disorder were examined. Reported childhood abuse was measured using the Childhood Experience of Care and Abuse interview...

BACKGROUND: Oral zuclopenthixol dihydrochloride (Clopixol) is an anti-psychotic treatment for people with psychotic symptoms, especially those with schizophrenia. It is associated with neuroleptic malignant syndrome, a prolongation of the QTc interval, extra-pyramidal reactions, venous thromboembolism and may modify insulin and glucose responses. OBJECTIVES: To determine the effects of zuclopenthixol dihydrochloride for treatment of schizophrenia. SEARCH METHODS: We searched the Cochrane Schizophrenia Group's Trials Register (latest search 09 June 2015)...

BACKGROUND: Decline in cognitive functioning precedes the first psychotic episode in the course of schizophrenia and is considered a hallmark symptom of the disorder. Given the low incidence of schizophrenia, it remains a challenge to investigate whether cognitive decline coincides with disease-related changes in brain structure, such as white matter abnormalities. The 22q11.2 deletion syndrome (22q11DS) is an appealing model in this context, as 25% of patients develop psychosis. Furthermore, we recently showed that cognitive decline also precedes the onset of psychosis in individuals with 22q11DS...

AIM: Early intervention in psychosis (EIP) is a well-established approach with the intention of early detection and treatment of psychotic disorders. Its clinical and economic benefits are well documented. This paper presents basic aspects of EIP services, discusses challenges to their implementation and presents ideas and strategies to overcome some of these obstacles. METHODS: This paper is a narrative review about the evidence supporting EIP, with examples of successful implementation of EIP and of cases where major obstacles still need to be overcome...

INTRODUCTION: Forms of habitual substance use including cigarette smoking and alcohol consumption have been documented as risk factors of common mental disorders (CMDs). The effects of areca nut chewing on biophysiological tests, metabolic syndromes, and liver function have been reported previously; however, the relationship between areca nut chewing and CMDs remains unclear. This study examined the association between areca nut chewing and CMDs and explored the relationships between areca nut chewing and biophysiological indicators...

BACKGROUND: Trauma and adverse childhood experiences (ACE) occur more often in mental illness, including psychosis, than in the general population. Individuals with psychosis (cases) report a higher number and severity (dose) of adversities than healthy controls. While a dose-dependent increase of adversities has been related to more severe psychopathology, the role of type and timing is still insufficiently understood on the exacerbation of positive and negative psychotic symptoms. Moreover, dissociative symptoms were examined as potential mediator between adversities and severity of psychotic symptoms...

Purpose of the article: There are indications of altered immune activity in depressed and psychotic patients compared to healthy controls in several studies. To explore the clinical importance of this phenomenon we examined the relation between different disorders affecting the immune system and psychoses and depression, respectively. MATERIALS AND METHODS: A total of 276 patients consecutively admitted to a psychiatric acute ward were included in the study. Of these 41 patients fulfilled the criteria for ICD-10 F20-29 (psychotic) diagnosis and 157 patients a F30-39 (affective) diagnosis...

OBJECTIVE: 22q11.2 deletion syndrome (22q11.2DS) is a neurogenetic disorder whose phenotype includes high rates of a schizophrenia-like psychotic disorder and immune system abnormalities. Thus, 22q11.2DS is an ideal model for studying the relationship between psychosis and inflammation. The aim of the present study was to identify inflammatory markers that may play a role in the pathophysiologic pathways associated with psychosis and cognitive deficits in 22q11.2DS. METHODS: Forty-nine individuals with 22q11...

Sexual offending is a public health concern and societal risk requiring a multi-disciplinary approach. While current data give an indication of the frequency of sexual victimization, these figures likely underestimate the severity of the concern as many of these incidents go unreported. And while sex offender research has increased over the past several decades, particular attention to those offenders with severe mental illness remains limited. In this descriptive review, literature describing sex offenders with psychotic disorders is explored with a focus on recent research...

REVIEW

Despite a growing body of evidence on motor dysfunction in schizophrenia spectrum disorders, the neuronal correlates of genuine motor abnormalities (GMA) are not fully elucidated at present. Moreover, the clinical relevance of a potential "motor intermediate phenotype" remains controversial. This systematic review aims at characterizing a "motor intermediate phenotype" in schizophrenia spectrum disorders. The second goal of this systematic review is to discuss GMA-associated brain alterations as potential biomarkers of psychosis risk syndrome and manifest motor symptoms against the background of current neuroimaging evidence...

BACKGROUND: There is evidence to suggest that people with established psychotic disorders show impairments in the mismatch negativity induced by a frequency-deviant sound (fMMN), and that these impairments worsen with the deterioration of psychotic symptoms. This study aimed to test whether individuals at ultra-high risk (UHR) for psychosis show pre-morbid impairments in fMMN, and if so, whether fMMN continues to deteriorate with transition to psychosis. METHOD: fMMN was recorded in a cohort of UHR individuals (n=42) and compared to healthy controls (n=29)...

There is strong evidence of ethnic disparities in chronic medical conditions, such as diabetes and cardiovascular diseases; however, less is known about ethnic differences in mental illness and health service utilization. Previous studies have shown that Asians are more likely to avoid or delay seeking help for their mental illness. We conducted a population-based study using Ontario health administrative data to examine ethnic differences in mental illness severity at hospital presentation. We found that Chinese and South Asian psychiatric patients were significantly more likely to be involuntarily admitted and exhibited more aggressive behaviours and psychotic symptoms compared to the general population...

Psychosis is common in Parkinson's disease (PD), especially in advanced disease, and can lead to a number of psychotic symptoms, including delusions. One uncommon delusion is Capgras syndrome (CS). The authors report on three PD patients with a history of deep brain stimulation (DBS) who developed this delusion. The anatomic targets in these three patients were the subthalamic nuclei in two patients and the globus pallidus interna in one patient. The length of time between surgery and development of CS varied but was greater than 6 months...

According to a widely held view, psychotic disorders such as schizophrenia are characterized by a vague boundary between the perception of the external world and the inner imagery of persons, objects, and events. In this study, we addressed the perception-imagery debate in schizotypal personality disorder (SPD). Thirty individuals with SPD and 30 matched healthy subjects completed a lateral masking task. Participants were asked to detect a low-contrast Gabor patch flanked by two collinear Gabor masks. In the perceptual task, the masks were physically present, whereas in the imagery task, participants only imagined the masks...

The motility psychoses are a group of acute psychiatric conditions characterized by salient disorders of movement (increased, decreased and disorganized), psychotic experiences, confusion and good prognosis. The debate on whether they are just atypical forms of schizophrenia or manic-depressive insanity or constitute an independent group of psychoses has not yet been settled. Erik Strömgren's classical chapter deals with the history and clinical aspects of the motility psychoses. Based on a historical analysis and an empirical study of a patient cohort, the author draws conclusions on the nature of this clinical group that has stood the test of time well...
