Neurocognition in adolescents and young adults at clinical high risk for psychosis: Predictive stability for social and role functioning. Schizophr Res 2024; 271:129-137. [PMID: 39024961 DOI: 10.1016/j.schres.2024.06.054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 06/25/2024] [Accepted: 06/28/2024] [Indexed: 07/20/2024]
Abstract
The prodromal phase of schizophrenia provides an optimal opportunity to mitigate the profound functional disability that is often associated with fully expressed psychosis. Considerable evidence supports the importance of neurocognition in the development of interpersonal (social) and academic (role) skills. Further findings from adolescents and young adults at clinical high risk for developing psychosis (CHRP) suggest that treatment for functioning might be most effective when targeting early and specific neurocognitive deficits. The current study addresses this critical intervention issue by examining the potential of neurocognitive deficits at intake for predicting social and role functioning over time in CHR-P youth. The study included 345 CHR-P participants from the second phase of the North American Prodrome Longitudinal Study (NAPLS2) with baseline neurocognition and 2-year follow-up data on social and role functioning. Slower baseline processing speed consistently predicted poor social functioning over time, while attention deficits predicted poor role functioning at baseline and follow-up. In addition, the impact of processing speed and attention impairments on social and role functioning, respectively, persisted even when adjusting the regression models for attenuated positive, negative, and disorganized symptoms, and transition status. The current study demonstrates for, arguably the first time, that processing speed and attention are strongly predictive of social and role functioning over time, respectively, above and beyond the impact of symptoms and those CHR-P individuals that develop psychosis over the course of the study. These findings imply that early neurocognition is a critical treatment target linked to the developmental trajectory of social and role functioning.

A multivariate cognitive approach to predict social functioning in recent onset psychosis in response to computerized cognitive training. Prog Neuropsychopharmacol Biol Psychiatry 2024; 128:110864. [PMID: 37717645 DOI: 10.1016/j.pnpbp.2023.110864] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 08/01/2023] [Accepted: 09/13/2023] [Indexed: 09/19/2023]
Abstract
Clinical and neuroimaging data has been increasingly used in recent years to disentangle heterogeneity of treatment response to cognitive training (CT) and predict which individuals may achieve the highest benefits. CT has small to medium effects on improving cognitive and social functioning in recent onset psychosis (ROP) patients, who show the most profound cognitive and social functioning deficits among psychiatric patients. We employed multivariate pattern analysis (MVPA) to investigate the potential of cognitive data to predict social functioning improvement in response to 10 h of CT in patients with ROP. A support vector machine (SVM) classifier was trained on the naturalistic data of the Personalized Prognostic Tools for Early Psychosis Management (PRONIA) study sample to predict functioning in an independent sample of 70 ROP patients using baseline cognitive data. PRONIA is a part of a FP7 EU grant program that involved 7 sites across 5 European countries, designed and conducted with the main aim of identifying (bio)markers associated with an enhanced risk of developing psychosis in order to improve early detection and prognosis. Social functioning was predicted with a balanced accuracy (BAC) of 66.4% (Sensitivity 78.8%; Specificity 54.1%; PPV 60.5%; NPV 74.1%; AUC 0.64; P = 0.01). The most frequently selected cognitive features (mean feature weights > ± 0.2) included the (1) correct number of symbol matchings within the Digit Symbol Substitution Test, (2) the number of distracting stimuli leading to an error within 300 and 200 trials in the Continuous Performance Test and (3) the dynamics of verbal fluency between 15 and 30 s within the Verbal Fluency Test, phonetic part. Next, the SVM classifier generated on the PRONIA sample was applied to the intervention sample, that obtained 54 ROP patients who were randomly assigned to a social cognitive training (SCT) or treatment as usual (TAU) group and dichotomized into good (GF-S ≥ 7) and poor (GF-S < 7) functioning patients based on their level of Global Functioning-Social (GF-S) score at follow-up (FU). By applying the initial PRONIA classifier, using out-of-sample cross-validation (OOCV) to the sample of ROP patients who have undergone the CT intervention, a BAC of 59.3% (Sensitivity 70.4%; Specificity 48.1%; PPV 57.6%; NPV 61.9%; AUC 0.63) was achieved at T0 and a BAC of 64.8% (Sensitivity 66.7%; Specificity 63.0%; PPV 64.3%; NPV 65.4%; AUC 0.66) at FU. After SCT intervention, a significant improvement in predicted social functioning values was observed in the SCT compared to TAU group (P ≤0.05; ES[Cohens' d] = 0.18). Due to a small sample size and modest variance of social functioning of the intervention sample it was not feasible to predict individual response to SCT in the current study. Our findings suggest that the use of baseline cognitive data could provide a robust individual estimate of future social functioning, while prediction of individual response to SCT using cognitive data that can be generated in the routine patient care remains to be addressed in large-scale cognitive training trials.

Abstract
Introduction Processing speed is defined as the ability to quickly process information, which is generally considered as one of the affected cognitive functions of multiple sclerosis and schizophrenia. Paper-pencil type tests are traditionally used in the assessment of processing speed. However, these tests generally need to be conducted under the guidance of clinicians in a specific environment, which limits their application in cognitive assessment or training in daily life. Therefore, this paper proposed an intelligent evaluation method of processing speed to assist clinicians in diagnosis. Methods We created an immersive virtual street embedded with Stroop task (VR-Street). The behavior and performance information was obtained by performing the dual-task of street-crossing and Stroop, and a 50-participant dataset was established with the label of standard scale. Utilizing Pearson correlation coefficient to find the relationship between the dual-task features and the cognitive test results, and an intelligent evaluation model was developed using machine learning. Results Statistical analysis showed that all Stroop task features were correlated with cognitive test results, and some behavior features also showed correlation. The estimated results showed that the proposed method can estimate the processing speed score with an adequate accuracy (mean absolute error of 0.800, relative accuracy of 0.916 and correlation coefficient of 0.804). The combination of Stroop features and behavior features showed better performance than single task features. Discussion The results of this work indicates that the dual-task design in this study better mobilizes participants' attention and cognitive resources, and more fully reflects participants' cognitive processing speed. The proposed method provides a new opportunity for accurate quantitative evaluation of cognitive function through virtual reality.

[PMID: 34522626 PMCID: PMC8427464 DOI: 10.1016/j.scog.2021.100207] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Revised: 07/04/2021] [Accepted: 07/04/2021] [Indexed: 12/01/2022]
Abstract
Objective The primary objective was to evaluate social cognitive complaints in a sample of chronic in-patients with schizophrenia and compare it to healthy controls. The secondary objective was to explore factors related to social cognitive complaints in these patients, such as neurocognition, clinical symptoms, depression, and insight. Methods A cross-sectional study conducted between July 2019 and March 2020 at the Psychiatric Hospital of the Cross (HPC)-Lebanon enrolled 120 chronic in-patients diagnosed with schizophrenia and schizoaffective disorders and 60 healthy controls. The Self-Assessment of Social Cognition Impairments (ACSo) scale was used to assess social cognitive complaints. Results A significant difference was found between schizophrenia patients and healthy controls in all social cognitive complaints: theory of mind complaint, attributional biases complaint, emotional processes complaint, and social perception and knowledge complaint (p < 0.001 for all). All objective cognitive disorders were significantly associated with social cognitive complaints except for attention and speed of information processing. Higher verbal memory and verbal fluency were significantly associated with lower emotional processes complaint scores. The results of the multivariate analysis showed that a higher cognition (Beta = −0.08, p = 0.001) was significantly associated with a lower social cognitive complaint, contrary a higher depression (Beta = 0.38, p = 0.04) was significantly associated with a higher social cognitive complaint, in particular attributional biases complaints. Conclusion This study showed that patients with schizophrenia have complaints about their social cognition. It could also demonstrate that subjective social cognitive complaints are correlated with depressive symptoms and objective cognitive deficits among these patients. Individuals with schizophrenia often have impairments in social cognition Despite low insight, patients report difficulties in their social cognitive skills. A correlation exists between neurocognition and subjective social cognition in schizophrenia Clinical symptoms (positive and negative symptoms) were not associated with social cognitive complaints Social cognitive complaints might help in cognitive remediation and therapy

Abstract
The main objective of this study was to evaluate the mentalizing performance of patients with schizophrenia who received daily psychosocial rehabilitation treatment compared with healthy controls. Differences in mentalizing performance between men and women, and the relationship between mentalizing deficits, cognitive impairment, symptoms, and global functioning of patients were also examined. A case-control study design was utilized (N = 95). Adults with schizophrenia were recruited from psychosocial rehabilitation clinics (n = 53) and healthy controls were recruited from the community (n = 42). Mentalizing was evaluated with the Movie for the Assessment of Social Cognition, an audiovisual measure with good ecological validity. Measures of cognitive functioning, symptoms, and global functioning were also administered. Patients exhibited significant mentalizing deficits. Specifically, patients made more undermentalizing errors and more no mentalizing errors compared with healthy controls. In patients and healthy controls, no differences were found between men and women in mentalizing abilities. In patients with schizophrenia, lower cognitive functioning (i.e., immediate and delayed verbal learning, verbal fluency, and processing speed) were associated with poorer mentalizing. In patients, processing speed explained 31% of the variance in total mentalizing errors and mentalizing deterioration was associated with poorer overall functioning. Psychosocial rehabilitation interventions in people with schizophrenia should consider mentalizing deficits (especially undermentalizing and no mentalizing difficulties) and their relationship with reduced processing speed in treatment delivery (e.g., direct and organized communication). Integration of treatments targeting mentalizing deficits in a psychosocial rehabilitation setting is recommended to improve functioning in schizophrenia.

Different neurocognitive profiles of risperidone and aripiprazole in the FIRST episode of psychosis: A 3-year follow-up comparison. Prog Neuropsychopharmacol Biol Psychiatry 2021; 110:110309.

Abstract
Cognitive deficits have been recognized as a central feature of schizophrenia spectrum disorders. These deficits are often related to more severe negative symptoms, as well as a poorer adjustment in social functioning. Therefore, it is important to improve cognitive performance from the onset of the disease. In this study, we compared the effects of two atypical antipsychotics, risperidone and aripiprazole, on cognition. The data used in the present investigation were obtained from a large epidemiological cohort of patients with a first episode of psychosis who were treated in a longitudinal intervention programme. The patients included in the program were randomized to treatment with risperidone or aripiprazole and were assessed for cognitive function at baseline and 3 years later. The final sample consisted of 115 patients, 55 of whom were initially assigned to risperidone and 60 to aripiprazole. The groups did not show significant differences in their sociodemographic or clinical characteristics at intake. Longitudinal analyses showed that risperidone-treated patients improved in the processing speed domain at the 3-year follow-up, while the aripiprazole group showed better scores for the executive function domain. Our study shows slight differences between the effects of risperidone and aripiprazole on cognition, suggesting different patterns of efficacy on cognitive function that may warrant more thorough research to determine the beneficial effects of these drugs on cognition. Future studies should evaluate the effects of these treatments over longer follow-up periods using standardized tools for the assessment of cognitive function.

Abstract
INTRODUCTION The present study aimed to obtain a short form of the Spanish version of the WAIS-IV for patients diagnosed with schizophrenia that requires about half an hour to be administered. The reduced test can be very useful in clinical and research settings when an estimation of the intelligence quotient (IQ) is required to decide about intervention programs or to describe the sample. MATERIALS AND METHODS A sample of 143 patients participated in the study, 91 out of them were the test group, and the other 52 were used for a cross-validation analysis. To increase the content validity, the decision was made to create a short form composed of a subtest of each of the four cognitive domains that the scale measures. RESULTS Several analyses showed that the best combination was composed of the Information, Block Design, Arithmetic, and Symbol Search subtests. Nine different criteria were calculated to evaluate the quality of the short form. CONCLUSIONS The data showed very good results for the criteria: correlations, difference of means, and cross-validation. The results were satisfactory for: category agreement, band of error, clinical accuracy, and reliability.

Abstract
People with schizophrenia have difficulty recognizing the emotions in the facial expressions of others, which affects their social interaction and functioning in the community. Static stimuli such as photographs have been used traditionally to examine deficiencies in the recognition of emotions in patients with schizophrenia, which has been criticized by some authors for lacking the dynamism that real facial stimuli have. With the aim of overcoming these drawbacks, in recent years, the creation and validation of virtual humans has been developed. This work presents the results of a study that evaluated facial recognition of emotions through a new set of dynamic virtual humans previously designed by the research team, in patients diagnosed of schizophrenia. The study included 56 stable patients, compared with 56 healthy controls. Our results showed that patients with schizophrenia present a deficit in facial affect recognition, compared to healthy controls (average hit rate 71.6% for patients vs 90.0% for controls). Facial expressions with greater dynamism (compared to less dynamic ones), as well as those presented from frontal view (compared to profile view) were better recognized in both groups. Regarding clinical and sociodemographic variables, the number of hospitalizations throughout life did not correlate with recognition rates. There was also no correlation between functioning or quality of life and recognition. A trend showed a reduction in the emotional recognition rate as a result of increases in Positive and Negative Syndrome Scale (PANSS), being statistically significant for negative PANSS. Patients presented a learning effect during the progression of the task, slightly greater in comparison to the control group. This finding is relevant when designing training interventions for people with schizophrenia. Maintaining the attention of patients and getting them to improve in the proposed tasks is a challenge for today’s psychiatry.

[PMID: 33643211 PMCID: PMC7905222 DOI: 10.3389/fneur.2021.637895] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Accepted: 01/06/2021] [Indexed: 11/25/2022] Open
Abstract
Background: Cognitive impairment is a common feature of multiple sclerosis (MS). A semi-structured interview, including informant input, can characterize the experience of individuals living with MS and cognitive involvement. Objective: We administered the Cognitive Assessment Interview (CAI), a patient- and informant-based semi-structured interview, to characterize the experience of cognitive impairments in those living with MS. Methods: Trained raters administered the CAI to a sample of MS participants and their informants enrolled for a trial of cognitive remediation. Cognitive impairments on the CAI were characterized and compared to those captured by neuropsychological and self-report measures. Results: A total of n = 109 MS participants (mean age = 50.3 ± 12.2) and their available informants (n = 71) were interviewed. Participants reported experiencing processing speed (90/106, 85%), working memory (87/109, 80%), and learning and memory (79/109, 72%) problems most commonly. CAI-based ratings were moderately correlated with a self-report measure (Multiple Sclerosis Neuropsychological Screening Questionnaire, rs = 0.52, p < 0.001) and only mildly correlated with objective neuropsychological measures specific to executive functions (rs = 0.21, p = 0.029). For those with informant interviews, ratings were overall consistent, suggesting that the CAI is valid even in cases in which an informant is unavailable and the interview is conducted with the patient alone (as is often the case in clinical and research settings). Conclusions: The CAI provides a semi-structured interview to characterize the experience of cognitive impairment in MS, with findings representing real-world functioning, adding valuable information to both self-report measures and neuropsychological assessment.

[PMID: 33434726 PMCID: PMC7988290 DOI: 10.1016/j.schres.2020.11.053] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Revised: 11/16/2020] [Accepted: 11/30/2020] [Indexed: 11/26/2022]
Abstract
Imaging and postmortem studies indicate that schizophrenia subjects exhibit abnormal connectivity in several white matter tracts, including the cingulum bundle. Copper chelators given to experimental animals damage myelin and myelin-producing oligodendrocytes, and the substantia nigra of schizophrenia subjects shows lower levels of copper, copper transporters, and copper-utilizing enzymes. This study aimed to elucidate the potential role of copper homeostasis in white matter pathology in schizophrenia. Protein levels of the copper transporters ATP7A and CTR1, and dysbindin-1, an upstream modulator of copper metabolism and schizophrenia susceptibility factor, were measured using Western blot analyses of the postmortem cingulum bundle of schizophrenia subjects (n=16) and matched controls (n=13). Additionally, the patient group was subdivided by treatment status: off- (n=8) or on-medication (n=8). Relationships between proteins from the current study were correlated among themselves and markers of axonal integrity previously measured in the same cohort. Schizophrenia subjects exhibited similar protein levels to controls, with no effect of antipsychotic treatment. The dysbindin-1A/1BC relationship was positive in controls and schizophrenia subjects; however, antipsychotic treatment appeared to reverse this relationship in a statistically different manner from that of controls and unmedicated subjects. The relationships between dysbindin-1A/neurofilament heavy and ATP7A/α-tubulin were positively correlated in the schizophrenia group that was significantly different from the lack of correlation in controls. Copper transporters and dysbindin-1 appear to be more significantly affected in the grey matter of schizophrenia subjects. However, the relationships among proteins in white matter may be more substantial and dependent on treatment status.

Abstract
Introduction: Interest in the idea of recovery for certain patients with schizophrenia has been growing over the last decade. Improving symptomatology and functioning is crucial for achieving this. Our study aims to identify those factors that substantially contribute to real-world functioning in these patients. Methods: We carried out a cross-sectional study in stable outpatients with schizophrenia on maintenance antipsychotic monotherapy. Patients: We studied 144 outpatients with schizophrenia (DSM-IV-TR criteria) meeting the following criteria: (1) 18-65 years of age; (2) being clinically stable for at least the previous three months; (3) on maintenance antipsychotic monotherapy (prescriptions ≤ 10 mg olanzapine, ≤200 mg quetiapine, or ≤100 mg levomepromazine as hypnotics were also allowed); and (4) written informed consent. Assessment: We collected information on demographic and clinical variables by using an ad hoc questionnaire. For psychopathology, we employed the Spanish versions of the following psychometric instruments: the Positive and Negative Syndrome Scale (PANSS), the Brief Negative Symptom Scale (BNSS-Sp), and the Calgary Depression Scale (CDS). In addition, cognitive domains were assessed using the Verbal Fluency Test (VFT), the Digit Symbol Substitution Test (DSST), and the Trail Making Test, parts A and B (TMT-A and TMT-B). Finally, we employed the Spanish versions of the University of California San Diego Performance-based Skills Assessment (Sp-UPSA) and the Personal and Social Performance (PSP) for assessing functional capacity and real-world functioning, respectively. Statistical analysis: A forward stepwise regression was conducted by entering those variables significantly associated with PSP total score into the univariate analyses (Student's t-test, ANOVA with Duncan's post-hoc test, or bivariate Pearson correlation). Results: A total of 144 patients; mean age 40 years, 64% males, mean length of illness 12.4 years, PSP total score 54.3. The final model was a significant predictor of real-world functioning [F (7, 131) = 36.371, p < 0.001] and explained 66.0% of the variance. Variables retained in the model: BNSS-Sp abulia, asociality, and blunted affect, PANSS general psychopathology, Sp-UPSA transportation, TMT-B, and heart rate. Conclusion: Our model will contribute to a more efficient and personalized daily clinical practice by assigning specific interventions to each patient based on specific impaired factors in order to improve functioning.

Abstract
BACKGROUND Schizophrenia (SC), bipolar disorder (BD), and major depressive disorder (MDD) are associated with various cognitive and executive dysfunctions. The aim of the present study was to evaluate and compare cognitive and executive dysfunctions in schizophrenia, bipolar disorder, and major depressive disorder. MATERIALS AND METHODS Sixty-four schizophrenia patients, 68 bipolar patients, 62 patients with major depressive disorder, and 75 healthy individuals participated in the present study. All participants were assessed with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), Young Mania Rating Scale (YMRS), Positive and Negative Syndrome Scale (PANSS), Beck Depression Inventory (BDI-II), Trial Making Test (TMT), Four-Choice Reaction Time Task, Ruler Drop Method (RDM), Tower of London (TOL) task, and the Wisconsin Card Sorting Task (WCST). Data were analyzed by chi-square, Kolmogorov-Smirnov, and independent t-tests; ANOVA; and MANOVA. RESULTS In the cognitive function, the scores of SC, BD, and MDD patients were lower than those of healthy individuals. Also, the scores of MDD patients were lower than those of other patients, and the scores of BD patients were lower than those of SC patients. In the executive function, the scores of SC, BD, and MDD patients were lower than those of healthy individuals. Moreover, the scores of the MDD group were higher than those of the BD and SC groups, and the scores of the SC group were higher than those of the BD group. CONCLUSION Patients with SC, BD, and MDD have poorer cognitive and executive functions than healthy individuals, even when these patients are in a stable state. Assessment of cognitive and executive functions in SC, BD, and MDD patients can help in understanding the pathology of these disorders.

Abstract
INTRODUCTION The present study aimed to obtain a short form of the Spanish version of the WAIS-IV for patients diagnosed with schizophrenia that requires about half an hour to be administered. The reduced test can be very useful in clinical and research settings when an estimation of the intelligence quotient is required to decide about intervention programmes or to describe the sample. MATERIALS AND METHODS A sample of 143 patients participated in the study, 91 out of them were the test group, and the other 52 were used for a cross-validation analysis. To increase the content validity, the decision was made to create a short form composed of a subtest of each of the four cognitive domains that the scale measures. RESULTS Several analyses showed that the best combination was composed of the Information, Block Design, Arithmetic, and Symbol Search subtests. Nine different criteria were calculated to evaluate the quality of the short form. CONCLUSIONS The data showed very good results for the criteria: correlations, difference of means, and cross-validation. The results were satisfactory for: category agreement, band of error, clinical accuracy, and reliability.

Abstract
Introduction: Because of the importance of the assessment of social cognitive impairments in schizophrenia in clinical settings, a new computer application called SCAN (Social Cognition Analyzer applicatioN) was developed. Our first aim was to examine if patients diagnosed with schizophrenia could be differentiated from healthy individuals based on the results of SCAN, taking into consideration both response rates and response times. Our second aim was to create Scanalizer, as part of SCAN, to produce social cognitive profiles of individual patients. Materials and Methods: 86 patients (SG) and 101 healthy participants (CG) were examined with SCAN. The domains were: ToM, irony, metaphor, emotion perception from prosody and social perception. SCAN displayed the tasks, recorded the answers and the response times. For the differentiation of the two groups a two-dimensional scatter plot was used. For the graphical presentation of the social cognitive profile of patients, the calculation of the distributions of CG's results was made with Kolmogorov-Smirnov Goodness-of-fit Test and with the sum of squared residuals (SSR). Results: We found that the SG's response rates were significantly lower and the SG's response times were significantly slower compared to the CG in every condition. With the two-dimensional comparison of the summary response rates and the summary response times of the participants, the SG could be differentiated from the CG and this differentiation worked irrespective of age and education. For the graphical representation of social cognitive functions of patients, distributions of the results of the CG were calculated. We found normal distributions in the response times of all conditions and in the response rates of the ToM condition. In the low-end tail of the irony condition, and in the metaphor, social perception and emotional prosody conditions, power-law distributions were found. We also found that the summary response rates of the lowest performing 10% of the CG was in the same range as the summary response rates of all examined patients. Discussion: Scanalizer enables clinicians to measure and analyse social cognitive profiles of patients diagnosed with schizophrenia. Moreover, SCAN could also be used to detect social cognitive disabilities of vulnerable individuals.

Predicting real-world functioning in outpatients with schizophrenia: Role of inflammation and psychopathology. Psychiatry Res 2019; 280:112509.

Abstract
Several studies indicate that negative and cognitive symptoms are determining factors of functioning in patients with schizophrenia. However, they do not usually include biological aspects, such as inflammatory markers. The current prospective study aims to identify clinical and biological factors predicting real-world functioning, at baseline and at one-year follow-up, of outpatients in an early stage of schizophrenia. Sample consist of 73 clinically stable patients with schizophrenia, of which 57 completed the one-year follow-up. Accurate psychopathology, functioning, and cognitive assessments were performed at baseline and follow-up (Positive and Negative Syndrome, Brief Negative Symptom, Calgary Depression, Personal and Social Performance Scales, and MATRICS Cognitive Consensus Battery). Biological biomarkers including anthropometric data and blood parameters were collected. Pearson correlation and multiple regression analyses including potential confounding factors were performed. Negative symptoms (especially asociality and avolition), along with the inflammatory biomarker interleukin-2, are the most important determining factors of poor real-world functioning in early-stage schizophrenia. The previous functioning, along with baseline cognitive performance in attention and vigilance, predicts functioning at one-year follow-up in these patients. Strategies aimed at improving negative and cognitive symptoms, as well as modifying certain inflammatory pathways, should be the targets to achieve functional recovery in the first years of schizophrenia.

Abstract
Ageing seems to present a bias towards positive stimuli that might be reflected in response times. However, this process is more complex for middle-aged adults, and even more in schizophrenia. In order to examine this issue, an experimental study was carried out in which 48 participants were divided into two groups: an experimental group of 24 participants diagnosed with schizophrenia and a control group of 24 subjects with no disorders. The main objective of the study was to evaluate response time components according to the emotional valence of the stimulus, to test recognition and discrimination in both groups. A battery of 120 images from the International Affective Picture System (IAPS), representing positive, negative and neutral emotional valences, was employed. Response times were evaluated in terms of analysis of variance, as well as its inherent response times components. The results showed slower responses in the group with schizophrenia than in the control one. Moreover, a poorer performance was depicted in the latency components this group. Finally, a differential deficit pattern for emotion between groups was not found.

Abstract
BACKGROUND AND PURPOSE Imaging studies have shown that people with schizophrenia exhibit abnormal connectivity termed "dysconnectivity" in several white matter tracts, including the cingulum bundle (CB), corpus callosum (CC), and arcuate fasciculus (AF). This study aimed to elucidate potential contributors to schizophrenia "dysconnectivity." EXPERIMENTAL APPROACH Western blot analysis was used to compare protein levels of myelin basic protein, neurofilament heavy, autophagosome marker LC3, and microtubule marker α-tubulin in post-mortem human CB, CC, and AF in schizophrenia subjects (SZ) and matched normal controls (NC). Additionally, SZ cases were subdivided by treatment status: off-medication (OFF) or on-medication (ON). KEY RESULTS In the CC, the combined SZ group exhibited less neurofilament heavy protein than the NCs. In the CB, the combined SZ group had similar levels of α-tubulin protein versus NC, but OFF subjects had increased α-tubulin protein versus ON and NCs. There were significant correlations between α-tubulin and all other proteins but only in the CB. The strong negative relationship between α-tubulin versus myelin basic protein and α-tubulin versus LC3 in NCs was absent in SZs; coefficients comparison showed significant differences. Preliminary race analyses revealed that African American SZ had less AF α-tubulin than Caucasian SZ and African American normal controls. CONCLUSIONS AND IMPLICATIONS The results show a relationship between tract- and protein-specific abnormalities and diagnosis, treatment, and race. These data suggest there is a dysregulation of the relationship between α-tubulin and the other markers of white matter integrity observed in the CB in schizophrenia.

Abstract
OBJECTIVE Reduced performance in several cognitive domains has been repeatedly related to hepatitis C virus (HCV). Nevertheless, there is no consensus about the severity or cognitive profile. Moreover, other possible influential variables are scarcely controlled. The aim of this study is to define the specific cognitive profile in HCV after controlling for confounding variables. METHODS Forty-two HCV patients were distributed in 2groups according to the presence of co-infection with human immunodeficiency virus; a third group with 22 healthy controls was also included. The neuropsychological assessment included tests that assess processing speed, executive functioning, verbal memory, visual memory and working memory. Measures of depression (BDI), anxiety (HAM-A), fatigue (MAF), anhedonia (PAS), insomnia (ISI), quality of life (SF-36) and history of drug abuse (DAST-20) were taken in order to explore differences among groups and to control for their possible influence on cognitive performance. RESULTS HCV patients (including human immunodeficiency virus-coinfection) performed significantly worse in all cognitive measures. However, when the effect of BDI, HAM-A, MAF, ISI, SF-36 & DAST-20 was controlled, only verbal memory of HCV patients differed among groups. Coinfected patients performed worse in verbal memory. CONCLUSIONS According to previous studies verbal memory is the unique cognitive domain related to the effect of HCV. The present study does not support that the neurovirulence effect of HCV is decreasing cognitive performance in HCV patients. Nevertheless, the present study cannot relate the fronto-striatal disruption with the cognitive performance in HCV patients.
