Quality of clinical management of cardiometabolic risk factors in patients with severe mental illness in a specialist mental health care setting.

Purpose: Cardiometabolic disease in patients with severe mental illness is a major cause of shortened life expectancy. There is sparse evidence of real-world clinical risk prevention practice. We investigated levels of assessments of cardiometabolic risk factors and risk management interventions in patients with severe mental illness in the Norwegian mental health service according to an acknowledged international standard.

[The specialist health service for geriatric psychiatry during the COVID-19 pandemic].

Background: Older patients with mental disorders are particularly likely to be affected by negative consequences of the infection control measures that have been implemented as a result of the COVID-19 pandemic.

Material And Method: A questionnaire survey was sent to 18 departments of geriatric psychiatry from all four health regions in Norway.

Results: Altogether 83 therapists from various occupational groups responded, with representatives from all the health regions.

Psychodynamic case formulations without technical language: a reliability study.

Background: To bridge the gap between symptoms and treatment, constructing case formulations is essential for clinicians. Limited scientific value has been attributed to case formulations because of problems with quality, reliability, and validity. For understanding, communication, and treatment planning beyond each specific clinician-patient dyad, a case formulation must convey valid information concerning the patient, as well as being a reliable source of information regardless of the clinician's theoretical orientation.

Anxiety symptom levels are persistent in older adults with a mental disorder: A 33-month follow-up study.

Objective: Anxiety symptoms are common in old age and have been suggested as risk factors for development of cognitive impairment and mortality. The objective of the present study was to investigate whether anxiety symptoms among older adults with a mental health diagnosis are persistent, and severity of anxiety predicts cognitive decline and mortality.

Methods: We collected data from 201 patients referred to specialist mental health service in a department of geriatric psychiatry.

Cortical Brain Abnormalities in 4474 Individuals With Schizophrenia and 5098 Control Subjects via the Enhancing Neuro Imaging Genetics Through Meta Analysis (ENIGMA) Consortium.

Background: The profile of cortical neuroanatomical abnormalities in schizophrenia is not fully understood, despite hundreds of published structural brain imaging studies. This study presents the first meta-analysis of cortical thickness and surface area abnormalities in schizophrenia conducted by the ENIGMA (Enhancing Neuro Imaging Genetics through Meta Analysis) Schizophrenia Working Group.

Methods: The study included data from 4474 individuals with schizophrenia (mean age, 32.

Cortical thickness abnormalities in bipolar disorder patients with a lifetime history of auditory hallucinations.

Objectives: We aimed to investigate morphometric correlates of auditory hallucinations in bipolar disorder (BD) by comparing cortical thickness and cortical surface area in bipolar disorder patients with (BD+) and without (BD-) a lifetime history of auditory hallucinations. Based on previous findings in schizophrenia patients, we hypothesized that the cortex would be thinner in the auditory cortex in BD+ compared to BD-.

Methods: Bipolar disorder spectrum (n = 157) patients and healthy controls (n = 279) underwent 1.

Cortical thickness, cortical surface area and subcortical volumes in schizophrenia and bipolar disorder patients with cannabis use.

Cannabis is associated with increased risk for severe mental illness and is commonly used among individuals with schizophrenia or bipolar disorder. In this study we investigated associations between cannabis use and brain structures among patients with schizophrenia or bipolar disorders. Magnetic resonance imaging scans were obtained for 77 schizophrenia and 55 bipolar patients with a history of cannabis use (defined as lifetime use >10 times during one month or abuse/dependence), and 97 schizophrenia, 85 bipolar disorder patients and 277 healthy controls without any previous cannabis use.

Symptoms of Anxiety in Older Adults with Depression, Dementia, or Psychosis: A Principal Component Analysis of the Geriatric Anxiety Inventory.

Aims: The primary aim of this study was to examine anxiety symptoms as measured by the Geriatric Anxiety Inventory (GAI) in older patients with depression, dementia, or psychotic disorders. The secondary aim was to conduct a principal component analysis (PCA) of the GAI and to examine whether its subscales differ between the 3 disorders.

Methods: We included data from 428 patients who were admitted to a department of geriatric psychiatry and examined according to a standardized protocol.

Auditory Cortex Characteristics in Schizophrenia: Associations With Auditory Hallucinations.

Background: Neuroimaging studies have demonstrated associations between smaller auditory cortex volume and auditory hallucinations (AH) in schizophrenia. Reduced cortical volume can result from a reduction of either cortical thickness or cortical surface area, which may reflect different neuropathology. We investigate for the first time how thickness and surface area of the auditory cortex relate to AH in a large sample of schizophrenia spectrum patients.

Impaired Verbal Learning Is Associated with Larger Caudate Volumes in Early Onset Schizophrenia Spectrum Disorders.

Background: Both brain structural abnormalities and neurocognitive impairments are core features of schizophrenia. We have previously reported enlargements in subcortical brain structure volumes and impairment of neurocognitive functioning as measured by the MATRICS Cognitive Consensus Battery (MCCB) in early onset schizophrenia spectrum disorders (EOS). To our knowledge, no previous study has investigated whether neurocognitive performance and volumetric abnormalities in subcortical brain structures are related in EOS.

Lithium treatment and hippocampal subfields and amygdala volumes in bipolar disorder.

Objectives: Results from magnetic resonance imaging (MRI) studies are heterogeneous with regard to hippocampal and amygdala volume alterations in bipolar disorder (BD). Lithium treatment may influence both structures. It is unknown if lithium treatment has distinct effects on hippocampal subfield volumes and if subfield volumes change over the course of illness in BD.

Brain structure characteristics in intellectually superior schizophrenia.

The current study aims to fill a gap in the knowledge base by investigating the structural brain characteristics of individuals with schizophrenia and superior intellectual abilities. Subcortical volumes, cortical thickness and cortical surface area were examined in intellectually normal and intellectually superior participants with schizophrenia and their IQ-matched healthy controls, as well as in intellectually low schizophrenia participants. We replicated significant diagnostic group effects on hippocampal and ventricular size after correction for multiple comparisons.

Common genetic variants influence human subcortical brain structures.

The highly complex structure of the human brain is strongly shaped by genetic influences. Subcortical brain regions form circuits with cortical areas to coordinate movement, learning, memory and motivation, and altered circuits can lead to abnormal behaviour and disease. To investigate how common genetic variants affect the structure of these brain regions, here we conduct genome-wide association studies of the volumes of seven subcortical regions and the intracranial volume derived from magnetic resonance images of 30,717 individuals from 50 cohorts.

Reduced brain cortical folding in schizophrenia revealed in two independent samples.

The cerebral cortex is highly convoluted, and principal folding patterns are determined early in life. Degree of cortical folding in adult life may index aberrations in brain development. Results from previous studies of cortical folding in schizophrenia are inconsistent.

One year follow-up of alcohol and illicit substance use in first-episode psychosis: does gender matter?

Longitudinal studies on first-episode psychosis (FEP) patients have shown a decrease of substance use disorders (SUDs) over the first years of illness, but there has been less focus on the gender aspect. The present study examines stability of alcohol and illicit substance use, with specific focus on gender, in a one year follow-up investigation of 154 FEP patients (91 men, 63 women) in Oslo, Norway, using criteria for DSM-IV substance use disorder diagnosis, the Alcohol Use Disorders Identification Test (AUDIT) and the Drug Use Disorders Identification Test (DUDIT). The results show that cannabis was the most frequently used illicit substance at both times.

Schizophrenia--what does structural MRI show?

Background: Schizophrenia is a serious mental disorder that affects several brain functions. MRI technology has enabled in vivo studies of brain anatomy in patients with schizophrenia aimed at understanding more about the disorder.

Method: This article is based on a search in PubMed on «schizophrenia MRI» and on the authors' own research and experience.

ZNF804A and cortical thickness in schizophrenia and bipolar disorder.

ZNF804A SNP rs1344706 confers genome-wide risk for schizophrenia and bipolar disorder. Both disorders affect cortical thickness. To determine if single nucleotide polymorphisms (SNPs) across ZNF804A are associated with cortical thinning, we investigated 63 SNPs (including rs1344706) in 365 psychosis patients and healthy controls.

Normal birth weight variation is related to cortical morphology across the psychosis spectrum.

Background: Normal birth weight variation affects schizophrenia risk and cognitive performance in schizophrenia patients and healthy controls. Brain cortical anatomy is altered in psychotic disorders and in low birth weight subjects, but if birth weight variation relates to cortical morphology across the psychosis spectrum is not known.

Methods: Magnetic Resonance Imaging brain scans and clinical-, neurocognitive-, and medical birth registry data were collected from 359 adults including patients with a DSM-IV diagnosis of schizophrenia (n = 90, mean age 29.

A 5-year follow-up study of brain cortical and subcortical abnormalities in a schizophrenia cohort.

Background: Magnetic resonance imaging studies have demonstrated that patients with schizophrenia have thinner cortex in prefrontal and temporal brain regions, and enlarged lateral ventricles, compared to healthy subjects. Longitudinal studies have shown progressive brain tissue loss and ventricular dilatation among patients, predominantly in the early phase of the illness. Evidence for progression in more chronic phases of schizophrenia is less established.

Effect of DISC1 SNPs on brain structure in healthy controls and patients with a history of psychosis.

Disrupted-in-Schizophrenia-1 (DISC1) has been suggested as a susceptibility locus for a broad spectrum of psychiatric disorders. Risk variants have been associated with brain structural changes, which overlap alterations reported in schizophrenia and bipolar disorder patients. We used genome-wide genotyping data for a Norwegian sample of healthy controls (n = 171) and patients with a history of psychosis (n = 184), to investigate 61 SNPs in the DISC1 region for putative association with structural magnetic resonance imaging (sMRI) measures (hippocampal volume; mean cortical thickness; and total surface area, as well as cortical thickness and area divided into four lobar measures).

Cortical volume, surface area, and thickness in schizophrenia and bipolar disorder.

Background: Magnetic resonance imaging studies have shown that structural brain abnormalities are present in both schizophrenia and bipolar disorder. Most previous studies have focused on brain tissue volumes, but advances in neuroimaging data processing have made it possible to separate cortical area and cortical thickness. The purpose of the present study was to provide a more complete picture of cortical morphometric differences in schizophrenia and bipolar disorder, decomposing cortical volume into its constituent parts, cortical thickness and cortical area.

Common sequence variants in the major histocompatibility complex region associate with cerebral ventricular size in schizophrenia.

Background: Because of evidence from genetic linkage and genome-wide association studies, as well as suggested involvement of infection, the major histocompatibility complex (MHC) region on chromosome 6p21.3-22.1 has been implicated in the development of schizophrenia.

Subcortical brain volumes relate to neurocognition in schizophrenia and bipolar disorder and healthy controls.

Background: Similar patterns of subcortical brain abnormalities and neurocognitive dysfunction have been demonstrated in schizophrenia and bipolar disorder, with more extensive findings in schizophrenia. It is unknown whether relationships between subcortical volumes and neurocognitive performance are similar or different between schizophrenia and bipolar disorder.

Methods: MRI scans and neuropsychological test performance were obtained from 117 schizophrenia or 121 bipolar spectrum disorder patients and 192 healthy control subjects.
