Associations Between Schizophrenia Polygenic Liability, Symptom Dimensions, and Cognitive Ability in Schizophrenia

Schizophrenia is a clinically heterogeneous disorder. It is currently unclear how variability in symptom dimensions and cognitive ability is associated with genetic liability for schizophrenia. To determine whether phenotypic dimensions within schizophrenia are associated with genetic liability to schizophrenia, other neuropsychiatric disorders, and intelligence. In a genetic association study, 3 cross-sectional samples of 1220 individuals with a diagnosis of schizophrenia were recruited from community, inpatient, and voluntary sector mental health services across the UK. Confirmatory factor analysis was used to create phenotypic dimensions from lifetime ratings of the Scale for the Assessment of Positive Symptoms, Scale for the Assessment of Negative Symptoms, and the MATRICS Consensus Cognitive Battery. Analyses of polygenic risk scores (PRSs) were used to assess whether genetic liability to schizophrenia, other neuropsychiatric disorders, and intelligence were associated with these phenotypic dimensions. Data collection for the cross-sectional studies occurred between 1993 and 2016. Data analysis for this study occurred between January 2019 and March 2021. Outcome measures included phenotypic dimensions defined from confirmatory factor analysis relating to positive symptoms, negative symptoms of diminished expressivity, negative symptoms of motivation and pleasure, disorganized symptoms, and current cognitive ability. Exposure measures included PRSs for schizophrenia, bipolar disorder, major depression, attention-deficit/hyperactivity disorder, autism spectrum disorder, and intelligence. Of the 1220 study participants, 817 were men (67.0%). Participants' mean (SD) age at interview was 43.10 (12.74) years. Schizophrenia PRS was associated with increased disorganized symptom dimension scores in both a 5-factor model (β = 0.14; 95% CI, 0.07-0.22; P = 2.80 × 10-4) and a 3-factor model across all samples (β = 0.10; 95% CI, 0.05-0.15; P = 2.80 × 10-4). Current cognitive ability was associated with genetic liability to schizophrenia (β = -0.11; 95% CI, -0.19 to -0.04; P = 1.63 × 10-3) and intelligence (β = 0.23; 95% CI, 0.16-0.30; P = 1.52 × 10-10). After controlling for estimated premorbid IQ, current cognitive performance was associated with schizophrenia PRS (β = -0.08; 95% CI, -0.14 to -0.02; P = 8.50 × 10-3) but not intelligence PRS. The findings of this study suggest that genetic liability for schizophrenia is associated with higher disorganized dimension scores but not other symptom dimensions. Cognitive performance in schizophrenia appears to reflect distinct contributions from genetic liabilities to both intelligence and schizophrenia.

Enhancing stress reactivity and wellbeing in early schizophrenia: A randomized controlled trial of Integrated Coping Awareness Therapy (I-CAT)

Individuals with schizophrenia spectrum disorders (SSD) are at heightened risk for exposure to stressful life events which can lead to increased sensitivity to stress and a dysregulated stress response, which are in turn associated with poor long-term functioning. Stress reactivity is thus a promising treatment target in the early stages of SSD. Integrated-Coping Awareness Therapy (I-CAT) is a manualized intervention integrating mindfulness and positive psychology to target a dysregulated stress response in SSD. The current study is a preliminary randomized-controlled trial (RCT) comparing I-CAT (n = 18) with treatment as usual (TAU; n = 18) in individuals in the early stages of SSD. I-CAT was hypothesized to be more effective than TAU on primary outcomes: increasing positive emotions, decreasing negative emotions, reducing stress, and improving functioning and quality of life; and secondary outcomes: reducing symptoms, increasing mindfulness, and improving overall well-being. Excellent therapy attendance rates, low study attrition, and positive participant feedback demonstrated that I-CAT was a feasible and well-tolerated psychosocial intervention. Results suggest I-CAT led to greater reduction in symptoms (i.e., overall, negative, and disorganized symptoms), increased observational mindfulness, increased endorsement of a sense of purpose in life, and preservation of work abilities and school social functioning compared with TAU. Future work should replicate and extend these findings in a larger-scale RCT.

Clinical and psychological correlates of insight dimensions in patients with early psychosis.

To investigate correlates of insight dimensions in Chinese adult patients with early psychosis. Insight dimensions including awareness of mental disorder (AMD), illness consequences (AIC) and medication effect (AME) were measured. A wide array of variables encompassing demographics, premorbid adjustment, onset profiles, symptomatology, treatment characteristics and psychological factors were comprehensively assessed. Of 130 participants, 53.1%, 47.7% and 56.2% were categorized with good AMD, AIC and AME, respectively. Good AMD was associated with female gender, fewer positive and disorganization symptoms, more severe depression and greater self-stigma. Good AIC was related to female gender, more severe depression and greater self-stigma. Younger age of onset, fewer positive symptoms and greater service satisfaction associated with good AME. Poor insight is prevalent in early psychosis. Differential relationships of insight dimensions with other illness variables underscore the importance of multidimensional approach in insight evaluation, and suggest potential treatment target for insight enhancement.

Detecting formal thought disorder by deep contextualized word representations

Computational linguistics has enabled the introduction of objective tools that measure some of the symptoms of schizophrenia, including the coherence of speech associated with formal thought disorder (FTD). Our goal was to investigate whether neural network based utterance embeddings are more accurate in detecting FTD than models based on individual indicators. The present research used a comprehensive Embeddings from Language Models (ELMo) approach to represent interviews with patients suffering from schizophrenia (N=35) and with healthy people (N=35). We compared its results to the approach described by Bedi et al. (2015), referred to here as the coherence model. Evaluations were also performed by a clinician using the Scale for the Assessment of Thought, Language and Communication (TLC). Using all six TLC questions the ELMo obtained an accuracy of 80% in distinguishing patients from healthy people. Previously used coherence models were less accurate at 70%. The classifying clinician was accurate 74% of the time. Our analysis shows that both ELMo and TLC are sensitive to the symptoms of disorganization in patients. In this study methods using text representations from language models were more accurate than those based solely on the assessment of FTD, and can be used as measures of disordered language that complement human clinical ratings.

Examining disorganization in patients with first episode psychosis: Findings from a 1-year follow-up of the 'Parma early psychosis' program.

Disorganization has been considered as a clinical domain close to the core of psychosis. However, it has received poor attention, especially at the illness onset. Moreover, most of the studies examining disorganized symptoms have been conducted in patients with chronic psychosis and research in the early stages of illness is still relatively scarce. Thus, the aims of this study were (a) to longitudinally monitor the stability of disorganization in patients with first episode psychosis (FEP) across a 1-year follow-up period, and (b) to investigate any relevant association of disorganized symptoms with functioning, psychopathology and the specific treatment components of an 'early intervention in psychosis' (EIP) program along the 1year of follow-up. At baseline, 312 FEP participants (aged 12-35 years) completed the positive and negative syndrome scale (PANSS) and the global assessment of functioning (GAF). Spearman's correlations and multiple linear regression analysis were used. At baseline, disorganization showed significant associations with all PANSS subscores, and a relevant negative correlation with GAF score. Across the follow-up, FEP individuals showed a significant improvement in disorganization severity. This decrease was specifically related to both baseline antipsychotic dosage and the number of individual cognitive-behavioural therapy sessions offered across the 1-year follow-up period. Disorganization is clinically relevant in FEP patients, already ate the enrollment in an EIP program. However, it tends to improve over time together with the delivery of specialized, person-tailored FEP interventions within a specific EIP protocol.

Disorganization in first episode schizophrenia: Treatment response and psychopathological findings from the 2-year follow-up of the “Parma Early Psychosis” program

ObjectiveDisorganization is a core dimension of schizophrenia, yet it is relatively under-investigated compared to positive and negative ones, especially at the illness onset. Indeed, most of the empirical studies investigating the disorganized domain included patients with prolonged schizophrenia. Therefore, the aims of this research were (1) to monitor the longitudinal stability of disorganized symptoms in young patients with First Episode Schizophrenia (FES) along a 2-year follow-up period, and (2) to examine any significant association of disorganization with functioning, psychopathology and the specific treatment components of an “Early Intervention in Psychosis” (EIP) program across the 2 years of follow-up. MethodsAt baseline, 159 FES individuals (aged 12–35 years) completed the Positive And Negative Syndrome Scale (PANSS) and the Global Assessment of Functioning (GAF). Spearman's correlation coefficients and multiple linear regression analysis were carried out. ResultsDuring the follow-up period, disorganization had relevant enduring positive associations with PANSS negative symptoms, lack of judgment/insight and positive symptoms representing delusional thought contents, as well as significant enduring negative correlation with GAF scores. Along the 2 years of follow-up, FES patients also showed a relevant improvement in disorganization symptoms. This reduction was specifically associated with the number of individual psychotherapy sessions provided during the first year of treatment. ConclusionDisorganization is a prominent clinical feature in FES at the recruitment in specialized EIP services, but its temporal trajectory reveals a decrease over time, together with the delivery of specific, patient-tailored EIP interventions.

Executive dysfunction in schizophrenia: Predictors of the discrepancy between subjective and objective measures

This study aimed to investigate what characterizes individuals with schizophrenia who experience more or less subjective executive dysfunction in everyday life compared to objective executive performance on neuropsychological tests.Sixty-six participants with broad schizophrenia spectrum disorders completed a comprehensive assessment of executive function. Discrepancies between performance on neuropsychological tests (objective) and an extensive self-report questionnaire (subjective) of central executive functions (inhibition, shifting and working memory) were calculated. Higher level of self-efficacy was the best predictor of experiencing fewer subjective cognitive complaints compared to objective performance, followed by higher levels of disorganized symptoms. Depressive symptoms did not predict discrepancy between subjective and objective executive function. Higher estimated IQ predicted greater subjective working memory difficulties in everyday life despite better objective performance.Results may aid clinicians in the assessment and remediation of cognitive impairment. Low self-efficacy may identify individuals who are not able to utilize their potential executive functions in daily life. Interventions aimed at fostering self-efficacy ought to be included in cognitive remediation for these individuals. Disorganized symptoms could prove useful in identifying individuals who are in need of cognitive remediation for executive dysfunction, despite that they overestimate their skills. These individuals may benefit from efforts to increase insight into cognitive dysfunction.

Beta-frequency electrophysiological bursts: BOLD correlates and relationships with psychotic illness

AimsTo identify the BOLD (blood oxygenation level dependent) correlates of bursts of beta frequency band electrophysiological activity, and to compare BOLD responses between healthy controls and patients with psychotic illness.The post movement beta rebound (PMBR) is a transient increase in power in the beta frequency band (13-30 Hz), recorded with methods such as electroencephalography (EEG), following the completion of a movement. PMBR size is reduced in patients with schizophrenia and inversely correlated with severity of illness. PMBR size is inversely correlated with measures of schizotypy in non-clinical groups. Therefore, beta-band activity may reflect a fundamental neural process whose disruption plays an important role in the pathophysiology of schizophrenia. Recent work has found that changes in beta power reflect changes in the probability-of-occurrence of transient bursts of beta-frequency activity. Understanding the generators of beta bursts could help unravel the pathophysiology of psychotic illness and thus identify novel treatment targets.MethodEEG data were recorded simultaneously with BOLD data measured with 3T functional magnetic resonance imaging (fMRI), whilst participants performed an n-back working memory task. We included seventy-eight participants – 32 patients with schizophrenia, 16 with bipolar disorder and 30 healthy controls. Beta bursts were identified in the EEG data using a thresholding method and burst timings were used as markers in an event-related fMRI design convolved with a conventional haemodynamic response function. A region of interest analysis compared beta-event-related BOLD activity between patients and controls.ResultBeta bursts phasically activated brain regions implicated in coding task-relevant content (specifically, regions involved in the phonological representation of letter stimuli, as well as areas representing motor responses). Further, bursts were associated with suppression of tonically-active regions. In the EEG, PMBR was greater in controls than patients, and, in patients, PMBR size was positively correlated with Global Assessment of Functioning scores, and negatively correlated with persisting symptoms of disorganisation and performance on a digit symbol substition test. Despite this, patients showed greater, more extensive, burst-related BOLD activation than controls.ConclusionOur findings are consistent with a recent model in which beta bursts serve to reactivate latently-maintained, task-relevant, sensorimotor information. The increased BOLD response associated with bursts in patients, despite reduced PMBR, could reflect inefficiency of burst-mediated cortical synchrony, or it may suggest that the sensorimotor information reactivated by beta bursts is less precisely specified in psychosis. We propose that dysfunction of the mechanisms by which beta bursts reactivate task-relevant content can manifest as disorganisation and working memory deficits, and may contribute to persisting symptoms and impairment in psychosis.

Narcolepsy and psychosis: A systematic review.

ObjectiveNarcolepsy is a rare sleep disorder in which psychotic‐like symptoms can present diagnostic and therapeutic challenges. We aimed to review the association between, and medical management of, narcolepsy and psychosis in children and adults.MethodsWe reviewed the full text of 100 papers from 187 identified by a PubMed search on narcolepsy plus any of these keywords: psychosis, schizophrenia, delusion, side effects, safety, and bipolar disorder.ResultsThree relevant groups are described. (i) In typical narcolepsy, psychotic‐like symptoms include predominantly visual hallucinations at the sleep‐wake transition (experienced as “not real”) and dissociation because of intrusion of rapid eye movement (REM) sleep phenomena into wakefulness. (ii) Atypical patients (“the psychotic form of narcolepsy”) experience more severe and vivid, apparently REM‐related hallucinations or dream/reality confusions, which patients may rationalize in a delusion‐like way. (iii) Some patients have a comorbid schizophrenia spectrum disorder with psychotic symptoms unrelated to sleep. Psychostimulants used to treat narcolepsy may trigger psychotic symptoms in all three groups. We analyzed 58 published cases from groups 2 and 3 (n = 17 and 41). Features that were reported significantly more frequently in atypical patients include visual and multimodal hallucinations, sexual and mystical delusions, and false memories. Dual diagnosis patients had more disorganized symptoms and earlier onset of narcolepsy.ConclusionEpidemiological studies tentatively suggest a possible association between narcolepsy and schizophrenia only for very early‐onset cases, which could be related to the partially overlapping neurodevelopmental changes observed in these disorders. We propose a clinical algorithm for the management of cases with psychotic‐like or psychotic features.

Frequency-Domain Error Processing Activity in Individuals at Clinically High Risk for Psychosis

Deficits in error processing are a cognitive component of schizophrenia-spectrum disorders, a finding supported by evidence from event-related potentials (ERPs). The error-related negativity (ERN), specifically, has been linked most closely to the intensity of negative symptoms (e.g., anhedonia or avolition), compared to positive and disorganized symptoms, in both schizophrenia patients and persons at clinical high risk (CHR) for the disorder. This literature, however, is limited to the time domain, while time-frequency decomposition may yield a more robust measure of such activity.

Basic self-disturbance in subjects at clinical high risk for psychosis: Relationship with clinical and functional outcomes at one year follow-up

Basic self-disturbance (BSD) is assumed to drive symptom development in schizophrenia spectrum disorders and in clinical high-risk (CHR) for psychosis. We investigated the relationship between BSD at baseline, assessed with the Examination of Anomalous Self-Experience (EASE), and symptoms and functional outcome after one year in 32 patients, including 26 CHR and six with non-progressive attenuated psychotic symptoms. Correlations between baseline BSD levels and positive, negative and disorganization symptoms, and global functioning level at follow-up were significant. Hierarchical regression analyses revealed that higher levels of baseline BSD predicted more severe positive symptoms and lower global functioning at follow-up, after adjusting for baseline positive symptoms and functioning. Subjects who were not in symptomatic and functional remission after one year had higher levels of BSD and negative symptoms, and lower functioning level, at baseline. Baseline BSD in participants with schizophrenia spectrum diagnoses at follow-up (9 of 12 were schizotypal personality disorder) were at the levels seen in schizotypal disorders in previous studies, but not significantly different from the other participants. Early identification and assessment of BSD may constitute a useful prognostic tool and a signal for therapeutic targets in CHR conditions. Further CHR studies investigating these relationships with larger samples are recommended.

Psychopathological Impact and Resilient Scenarios in Inpatient with Schizophrenia Spectrum Disorders Related to Covid Physical Distancing Policies: A Systematic Review.

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). Between November 2020 and January 2021, 5353 articles were collected and analyzed from the databases of the ResearchGate, Pubmed, and Psycnet websites, subjected to PRISMA methodology. Of these, 11 were evaluated for eligibility, but only three were included in the study because they met all inclusion criteria. The research did not confirm the expected results, showing that any kind of worsening of schizophrenic symptomatology involved the study samples. However, interesting outcomes were highlighted, such as a significant increase in general well-being during the early period of the pandemic, especially by women, or an increase in CPR (C-reactive Protein) levels in the blood, signaling an inflammatory state. Although the systematic review refuted the initial hypothesis, this must be a starting point: the topic is recent and these findings leave ample room for further investigation, particularly in long-term longitudinal research. It is possible that the true response to this disruption of daily life that occurred only during the past year may manifest itself later in time. On the other hand, interesting outcomes have been brought to light that may provide further interesting research insights.

The Clinical Course and Prognostic Problems of Youth Depressions with Attenuated Schizophrenic Symptoms

Objective Clinical and follow-up verification of Attenuated Schizophrenic Symptoms (ASS) in the first youth depressive episode as early markers of the schizophrenic process, establishing further variants of the course of the disorder and its outcomes.Materials and methods. 124 young inpatients (averaged age 19,6±2,3 years) with the first depressive episode with ASS were examined. The control group consisted of 27 patients with youth depression without ASS. All patients have been tracked for at least five years. The average follow-up period was 7,1±1,6 years. The HDRS, SOPS, SANS and PSP scales were used to assess the symptomatic and functional outcomes. Statistical analysis was carried out using STATISTICA 12.Results. The typological classification of youth depressions (ASD) with ASS has been developed with the identification of three main types: (1) with attenuated positive symptoms (APS), (2) with attenuated negative symptoms (ANS), and (3) with attenuated symptoms of disorganization. Youth depression with ASS, compared to the control group, is more likely to move into chronic forms, has reliably worse functional and symptomatic outcomes, and is more associated with the diagnosis of schizophrenic spectrum disorders at five years follow-up.Conclusion. Attenuated schizophrenic symptoms in the structure of youth depressions have high affinity to each other, indicating a common pathogenic mechanism of their formation, and also have predicate value as risk factors for schizophrenia.

The Relationship Between Different Aspects of Theory of Mind and Symptom Clusters in Psychotic Disorders: Deconstructing Theory of Mind Into Cognitive, Affective, and Hyper Theory of Mind.

Background: Several meta-analyses highlight pronounced problems in general Theory of Mind (ToM), the ability to infer other persons' mental states, in patients with psychosis in comparison to non-clinical controls. In addition, first studies suggest associations between Hyper-ToM, an exaggerated inference of mental states to others, and delusions. Research on different ToM subtypes (Cognitive ToM, Affective ToM, and Hyper-ToM) and symptom clusters of psychosis (positive, negative, and disorganized symptoms) have gathered conflicting findings. Thus, the present study examined group differences between patients with psychosis and non-clinical controls concerning Cognitive ToM/Affective ToM and Hyper-ToM. Further, the association between ToM subtypes and symptom clusters (positive, negative, and disorganized symptoms) were examined.Methods: Patients with psychotic disorders (n = 64, 1/3 with present delusions indicated by a minimum score of four in the PANSS P1 item) and non-clinical controls (n = 21) were examined with assessments of Cognitive ToM and Affective ToM abilities and Hyper-ToM errors using the Frith-Happé animations. Psychopathology was assessed using the Positive and Negative Syndrome Scale.Results: Patients with psychosis presented more pronounced problems in Cognitive and Affective ToM in comparison to non-clinical controls, whereas there were no group differences with regard to Hyper-ToM errors. Furthermore, deficits in Cognitive ToM were associated with general delusions, whereas problems in Affective ToM were associated with negative and disorganized symptoms. In addition, there was no association between Hyper-ToM errors and any symptoms when controlling for years of education.Conclusions: Our findings suggest that deficits in ToM subtypes might not be directly related to delusions and positive symptoms and are in line with more recently developed cognitive models of delusions. In addition, our results support the well-established finding of associations between ToM alterations and negative or disorganized symptoms. Our results shed light on the role of different dimensions of ToM in specific symptoms of psychosis.

What is important for doctor’s drug decision-making for the patient with acute schizophrenia?

IntroductionIn spite of the long history of antipsychotic treatment there are still no clear criteria, which can be robust support for drug decision-making.ObjectivesTo determine the important hallmarks of patient’s current state, life span and history of illness defining the doctor’s decision about the type of antipsychotic to be chosen.MethodsThe data from the case charts of 275 patients with episodic schizophrenia and rather benign course of the disease were analyzed.ResultsThe group included: male 62%, mean age 33 (SD 11), education 10 years 23%, 13 years 27%, 16 years 29%, disability - 51%, number of hospitalizations due to psychotic episodes in the past 7 (SD 6). The symptoms of the current episode varied from patient to patient: delusions and hallucinations, symptoms of disorganization, negative symptoms of different severity were registered Atypical antipsychotics were more often than typical prescribed to the patients with developmental problems: traumatic obstetric complications (p=0,009), poor somatic health in the childhood (p= 0,02), cognitive dysfunction during school years (p=0,04), and quality of first remission – presence of residual symptoms in the first remission (p=0.005). Good compliance in the past was one more important factor for choosing a atypical antipsychotic for a patient (p=0.05). It appeared that the most important for the decision-making was the specific features of the patient’s development and early period of the disease, but not the specific signs of current psychotic state.ConclusionsDoctor’s decision upon the type of antipsychotics in this category of patients is most probably based on other than current clinical symptoms signs.

Effectiveness of cognitive remediation in schizophrenia: What works and what does not work?

Introduction: Cognitive function in schizophrenia is one of the main elements related to functional outcomes. Although there is enough evidence that cognitive remediation (CR) is beneficial, there is still a limited understanding of how the active therapy ingredients contribute to brain changes and translate into improved real-world functioning. Objectives: Identify neurobiological, psychopathological, cognitive, and functional CR response or resistance predictors in schizophrenia, considering both cognitive and functional outcomes. Results: We still lack a precise understanding of how CR produce its effects with different programs, different numbers of sessions, with and without a therapist. CR exerts its maximal benefit when delivered in the context of psychiatric rehabilitation, but it is not yet clear what are the mechanisms of integrated treatment effectiveness. Only a few studies have looked for the relationship between CR response or resistance and the biological, socio-demographic, clinical and cognitive features in schizophrenia. The current knowledge on efficacy predictors of CR is sparse and include: age, illness duration, premorbid adjustment, baseline cognitive performance, intrinsic motivation, hostility, disorganized symptoms, neurobiological reserve, genetic polymorphisms, antipsychotics amount, the type of CR, etc. All of these limitations may have contributed to the poor implementation of CR in national and international guidelines, as well as in clinical practice. Conclusions: It is important that future research shift from studies of group efficacy to individual efficacy of treatments, in the perspective of precision medicine. Issues related to individual effectiveness predictors and interactions between specific pharmacologic, specific CR technique and individual patients’ characteristics should be further addressed.DisclosureNo significant relationships.

Clinical Features of Youth Depression with Attenuated Symptoms of the Schizophrenic Spectrum

Objective: establishment of clinical and psychometric features of youth depression with attenuated symptoms of the schizophrenic spectrum (ASSS) for early differential diagnosis and nosological assessment.Patients and methods: clinical and psychometric examination of young 219 inpatients (average age 19.6 ± 2.4 years), first admitted to the clinic “Mental Health Research Centre” from 2011 to 2020 with the first depressive episode with ASSS. Control group of inpatients (52 patients) with “classical” youth depressions without ASSS (average age 19.6 ± 2.4 years). Diagnosis according ICD-10: F32.1, F32.2, F32.28, F32.8.Results: the psychopathological structure of youth depression with ASSS is characterized by the following types: (1) depression with attenuated psychotic symptoms (APS), which were divided into the subtype (1a) depression with APS and (1b) depression with brief limited intermittent psychotic symptoms (BLIPS); (2) depression with attenuated negative symptoms (ANS), comprising two subtypes (2a) with most emotional damage and (2b) with volitional impairment, and type (3) with attenuated symptoms of disorganization (ASD) in the structure of depressive episode. Clinical and reliable psychometric differences have been established between depressions with ASSS and «classical» youth depressions without ASSS. Conclusions: youth depression with ASSS is definitely different from “classical” youth depression without ASSS. Differences have been found in the psychopathological structure of youth depression with ASSS, resulting in a typological differentiation.

Théorie de l’esprit : un médiateur entre symptômes et fonctionnement dans la schizophrénie ?

This literature review aimed to summarize the scientific knowledge concerning the links between psychosocial functioning and social cognition. Social cognition, and particularly Theory of Mind, is strongly disturbed in patients with schizophrenia. There were strong arguments that psychosocial functioning was more strongly associated with Theory of Mind than with neurocognition (defined as nonsocial information processing in contrast to social cognition). The functional capacity mediated this influence. Moreover, longitudinal studies suggested a unidirectional causal pathway with primary neurocognitive disorders leading to secondary deficits in social cognition, which in turn led to disturbances in psychosocial functioning. Studies using structural equation modelling showed that positive, negative and disorganization symptoms were associated with disturbances in psychosocial functioning. Regarding negative symptoms and disorganization, the influences were mediated by social cognition. The influence of positive symptoms on psychosocial functioning was independent of social cognition. This literature review suggests that social cognitive remediation in patients with should improve the psychosocial functioning in patients with schizophrenia.

The Association Between Psychopathology and Clinical Insight in Patients With Schizophrenia

In Taiwan, few studies have explored the associations between insight and psychopathological dimensions in people with schizophrenia. We aimed to investigate the relationships of clinical insight with different dimensional symptoms in patients with schizophrenia, in addition to clinical variables. This cross-sectional study recruited 90 patients from an acute psychiatric ward from December 2017 to May 2019. We assessed the insight of participants using the Schedule for Assessment of Insight in Psychosis (SIP) and psychopathology using the Positive and Negative Syndrome Scale and its five-factor model. A higher SIP score indicates a poorer insight. In regression analyses, patients' age (t = 3.277, p = 0.002), family history (t = -2.773, p = 0.007), Clinical Global Impressions Scale- Improvement (t = 2.268, p = 0.026), and negative (t = 2.667, p = 0.009), disorganized (t = 2.021, p = 0.047), excited (t = 3.087, p = 0.003), and depressed symptoms (t = -3.950, p ＜ 0.001) were significantly associated with the SIP score. In conclusion, patients with greater insight in the acute phase were associated with younger age, a positive family history, greater improvement of symptoms, less-severe negative symptoms, less-severe disorganized symptoms, less-severe excited symptoms, and more-severe depressed symptoms, but not with cognitive or executive function.
