insight in schizophrenic patients

OBJECTIVES: It has been reported that matrix metalloproteinase, MMP-3 may play a significant role in the pathophysiology of mental disorders. However, there are no data on the level of MMP-3 in people suffering from schizophrenia, or its influence on the mental state of these people. The aim of this study was to investigate the effect of an antipsychotic treatment on the blood levels of MMP-3, as well as investigating its relationship with insight into schizophrenia. METHODS: Thirty people with schizophrenia were included in the study...

Schizophrenia (SCZ) is associated with several immune dysfunctions, including elevated levels of pro-inflammatory cytokines. Microorganisms and their metabolites have been found to regulate the immune system, and that intestinal microbiota is significantly disturbed in schizophrenic patients. To systematically investigate aberrant gut-metabolome-immune network in schizophrenia, we performed an integrative analysis of intestinal microbiota, serum metabolome, and serum inflammatory cytokines in 63 SCZ patients and 57 healthy controls using a multi-omics strategy...

Schizophrenia patients often suffer from deficit in theory of mind (TOM). Prior neuroimaging studies revealed neuroimaging correlates of TOM deficit in adults with schizophrenia, neuroimaging correlates of TOM in adolescents is less well established. This study aimed to investigate gray matter volume (GMV) abnormalities and TOM deficits in schizophrenic adolescents, and examine the relationship between them. Twenty adolescent schizophrenic patients and 25 age, sex-matched healthy controls underwent T1-weighted magnetic resonance imaging (MRI) scans, and were examined for TOM based on the Reading the Mind in the Eyes test (RMET)...

Accumulating evidence suggests that deficits in perceptual inference account for symptoms of schizophrenia. One manifestation of perceptual inference is the central bias, i.e., the tendency to put emphasis on prior experiences over actual events in perceiving incoming sensory stimuli. Using an interval reproduction task, this study aimed to determine whether patients with schizophrenia show a stronger central bias than participants without schizophrenia. In the interval reproduction task, participants were shown a cross on a screen...

This essay presents two studies of Bertalan Petho's rich and diverse oeuvre. The first one (published in 1967) analyzed a schizophrenic composer-patient's composition created during the acute phase of schizophrenia and consi - dered the hiatus discursivitatis as one of the main characteristics of the pathology of expression in his musical works. The second study is the patients' catamnestic follow-up after 13 years. In that late, chronic, residual phase of schizophrenia with overwhelmingly negative symptoms, the mannieristic catatonia dominated the clinical feature, as well as the pathology of musical expression...

Evidence suggests that complex interactions between the immune system and brain have important etiological and therapeutic implications in schizophrenia. However, the detailed cellular and molecular basis of immune dysfunction in schizophrenia remains poorly characterized. To better understand the immune changes and molecular pathways, we systemically compared the cytokine responses of peripheral blood mononuclear cells (PBMCs) derived from patients with schizophrenia and controls against bacterial, fungal, and purified microbial ligands, and identified aberrant cytokine response patterns to various pathogens, as well as reduced cytokine production after stimulation with muramyl dipeptide (MDP) in schizophrenia...

Classical and contemporary phenomenological approaches in psychiatry describe schizophrenia as a disorder of common sense and self-affection. Although taking into account intersubjectivity, this conceptualization still puts forward an individualistic view of the disorder, that is, the intersubjective deficit resides within the person. To overcome such individualism, in this article, we first propose that schizophrenic experience might be understood as arising from a dialectic relation between the self's loss of openness to the world and the world's loss of openness to the self...

BACKGROUND: Diagnosis of schizophrenia lacks reliable medical diagnostic tests and robust biomarkers applied to clinical practice. Schizophrenic patients undergoing treatment with antipsychotics suffer reduced life expectancy due to metabolic disarrangements that co-exist with their mental illness and predispose them to develop metabolic syndrome, which is also exacerbated by medication. Metabolomics is an emerging and potent technology able to accelerate this biomedical research. AIM: This review focus on a detailed vision of the molecular mechanisms involved both in schizophrenia and antipsychotic-induced metabolic syndrome, based on innovative metabolites that consistently change in nascent metabolic syndrome, drug-naïve, first episode psychosis and/or schizophrenic patients compared to healthy subjects...

An altered sense of self-awareness and agency has been proposed to underlie symptoms of schizophrenia. In this study, we used the enfacement illusion paradigm - in which perception of another person's face leads to changes in perception of one's own peri-personal space - to examine the brain correlates of the sense of agency and its potential disruption in schizophrenia. Thirty-three schizophrenic patients and 27 healthy controls underwent fMRI scanning during performance of a task designed to elicit the enfacement illusion...

Cognitive dysfunction is one of the core symptoms in schizophrenia, and it is predictive of functional outcomes and therefore useful for treatment targets. Rather than improving cognitive deficits, currently available antipsychotics mainly focus on positive symptoms, targeting dopaminergic/serotoninergic neurons and receptors in the brain. Apart from investigating the neural mechanisms underlying schizophrenia, emerging evidence indicates the importance of glial cells in brain structure development and their involvement in cognitive functions...

BACKGROUND: Depressive disorders, despite being classified as mood or affective disorders, are known to include disturbances in the experience of body, space, time, and intersubjectivity. However, current diagnostic manuals largely ignore these aspects of depressive experience. In this article, we use phenomenological accounts of embodiment as a theoretical foundation for a qualitative study of abnormal body phenomena (ABP) in depressive disorders. METHODS: 550 patients affected by schizophrenic and affective disorders were interviewed in a clinical setting...

The lack of translation from basic research into new medicines is a major challenge in CNS drug development. The need to use novel approaches relying on (i) patient clustering based on neurobiology irrespective to symptomatology and (ii) quantitative biomarkers focusing on evolutionarily preserved neurobiological systems allowing back-translation from clinical to nonclinical research has been highlighted. Here we sought to evaluate the mismatch negativity (MMN) response in schizophrenic (SZ) patients, Alzheimer's disease (AD) patients, and age-matched healthy controls...

The COVID-19 epidemic posed great challenges to the healthcare community. To contain the epidemiological emergency, confinement measures were instituted, affecting the entire population. The lack of social contact, as well as the disruption of daily life, caused the exacerbation of anxiety and depressive symptoms. The present review of the literature aims to investigate what the effects of the pandemic have been on patients with schizophrenia, hypothesizing, an exacerbation of psychotic symptomatology (positive, negative, disorganized symptoms)...

INTRODUCTION: Toxoplasma gondii (T. gondii), a parasitic protozoa that is associated with various psychiatric disorders. Both T. gondii infection and disturbed host's lipid profile are common in schizophrenia patients. However, the underlying pathophysiological mechanisms remain speculative. Also, the characteristics of serum lipid levels in schizophrenia patients comorbid with T. gondii infection are not clear. Therefore, it is necessary to explore the influence of chronic T. gondii infection on the characteristic physiological indexes of schizophrenia patients so as to provide some insights into finding target therapeutic drugs...

Recent psychoneuroimmunology research has provided new insight into the etiology and pathogenesis of severe mental disorders (SMDs). The mild encephalitis (ME) hypothesis was developed with the example of human Borna disease virus infection years ago and proposed, that a subgroup SMD patients, mainly from the broad schizophrenic and affective spectrum, could suffer from mild neuroinflammation, which remained undetected because hard to diagnose with available diagnostic methods. Recently, in neurology an emerging new subgroup of autoimmune encephalitis (AE) cases suffering from various neurological syndromes was described in context with the discovery of an emerging list of Central Nervous System (CNS) autoantibodies...

BACKGROUND: Functional connections (FCs) methodology based on functional MRI data is an effective lever to investigate macroscopic neural activity patterns underlying critical aspects of cognition and behavior in schizophrenia (SZs). Dysconnectivity hypothesis are important features of SZs. However, region properties of brain network have been less investigated by special markers of graph indexes in general mental disorders. SUBJECTS AND METHODS: Region efficiency index are introduced to explore the information integration capacity among different regions and subsystems...

PURPOSE: There is a lack of research on predictors of criminal recidivism of offender patients diagnosed with schizophrenia. METHODS: 653 potential predictor variables were anlyzed in a set of 344 offender patients with a diagnosis of schizophrenia (209 reconvicted) using machine learning algorithms. As a novel methodological approach, null hypothesis significance testing (NHST), backward selection, logistic regression, trees, support vector machines (SVM), and naive bayes were used for preselecting variables...

PURPOSE: The aim of this study is to determine the relationship between sociodemographic characteristics and mindfulness-based psychoeducation given to schizophrenic patients for increasing insight. DESIGN AND METHODS: This study was conducted as pre-experimental single group pretest-posttest model in a Community Mental Health Center (CMHC) located in the city center of Balıkesir, Turkey, with 55 patients. FINDINGS: In patients graduating from university, posttest mean score of overall Beck Cognitive Insight Scale was higher than its pretest mean score and the difference between the mean scores was statistically significant (P < ...

BACKGROUND: Schizophrenia is a multifactorial neurodevelopmental disorder associated with cognitive dysfunction and changes in primary sensory processing. This article aims to explore the current insights into the relationship between schizophrenia and different visual disturbances. METHODS: To provide a literature review of visual impairments in schizophrenia, we performed a PubMed/MEDLINE and Scopus search to identify all articles in English on the topic up to the end of 2018...

BACKGROUND: In the last decade, there has been growing evidence that an interaction exists between inflammation and the kynurenine pathway in schizophrenia. Additionally, many authors found microglial activation in cases of schizophrenia due to inflammatory mechanisms related mostly to an increase of pro-inflammatory cytokines. In order to gain new insights into the pathophysiology of schizophrenia, it is important to incorporate the latest published evidence concerning inflammatory mechanisms and kynurenine metabolism...
