Disentangling Cognitive Heterogeneity in Psychotic Spectrum Disorders.

Neuropsychological impairments represent a central feature of psychosis-spectrum disorders. It is characterized by a great both within- and between-subjects variability (i.e. cognitive heterogeneity), which needs to be better disentangled. The present study aimed to describe the distribution of performance on the Brief Assessment of Cognition in Schizophrenia (BACS) by using the Equivalent Scores, in order to balance statistical methodological problems. To do so, cognitive performance groups were branded, identifying the main factors contributing to cognitive heterogeneity. A sample of 583 patients with a diagnosis of Schizophrenia or Psychotic Disorder Not Otherwise Specified was enrolled and assessed for neurocognition and intellectual level. K-means cluster analysis was performed based on BACS Equivalent Scores. Differences among clusters were analyzed throughout Analysis of Variance and Discriminant Function Analysis in order to identify the most significant predictors of cluster membership. For each cognitive task, roughly 40% of patients displayed poor performance, while up to 63% displayed a symbol-coding deficit. K-means cluster analysis depicted three profiles characterized by "near-normal" cognition, widespread impairment, and "borderline" profile. Discriminant analysis selected Verbal IQ and diagnosis as predictors of cluster membership. Our findings support the usefulness of Equivalent Scores and cluster analysis to explain cognitive heterogeneity, and tailor better interventions.

A leopard cannot change its spots: A novel pragmatic account of concretism in schizophrenia.

Concretism is a well-known feature of schizophrenia, tracing back to the early descriptions of the disease and commonly associated with the literal interpretation of figurative expressions such as proverbs, metaphors, and idioms. However, figurative expressions are not all alike in terms of linguistic and pragmatic processes. Determining if some figurative types are more impaired than others and if the type of task affects the performance constitutes an open issue with implications for the description of the clinical profile and for treatment. We run a fine-grained assessment of figurative language comprehension by comparing 47 patients with schizophrenia and 39 controls in three figurative types (idioms, metaphors, proverbs) presented in two response formats (multiple-choice, verbal-explanation), considering also the role of cognitive and clinical variables and the impact on quality of life. Mixed-effects models analysis revealed that: i) patients performed worse than controls across figurative types and response formats, indicating a diffuse impairment; ii) there is an interplay of figurative type and response format, which makes verbal-explanation of proverbs especially challenging; iii) in patients, problems in figurative language are largely connected with formal thought disorder and global IQ. Moreover, multiple-choice of metaphors was associated with patients' quality of life. This study offers a novel account of concretism, framed in pragmatics and figurative language processing. Adopting this perspective allowed us to describe the nuances of concretism, which areas in the figurative domain are especially challenging for patients and which ones capture differences in functioning, in order to guide intervention programs and integration in society.

The Influence of Premorbid Adjustment and Autistic Traits on Social Cognitive Dysfunction in Schizophrenia.

OBJECTIVES: Premorbid dysfunction during childhood and adolescence is well documented in patients with schizophrenia. Literature pointed out multiple premorbid trajectories leading to different patients' cognitive status, symptomatology, and global functioning after disease onset. This study aimed at identifying groups of premorbid trajectories and disentangling between group differences in clinical and cognitive measures, focusing on theory of mind (ToM) and autistic traits (ATs). METHODS: Ninety-seven patients with schizophrenia were recruited and assessed for cognitive and ToM abilities, psychopathology, and ATs. A two-step cluster analysis identified three different groups of patients based on premorbid adjustment during childhood, adolescence, and late adolescence (i.e., stable-good, stable-poor, and "deteriorating"). RESULTS: Compared to 66 healthy controls, results showed a widespread impairment in cognitive and ToM abilities among all groups of patients, except for affective ToM and executive functions in the stable-good group. Moreover, the stable-poor group exhibited more pronounced ATs and a more severe ToM impairment, compared to the other two groups of patients. CONCLUSIONS: Our findings highlight the existence of a group of patients with poor premorbid adjustment since childhood, more pronounced ATs and a severe ToM impairment affecting those basic mentalizing skills that are usually preserved in schizophrenia. Results might have intriguing implications in identifying underpinning endophenotypes and implementing cutting-edge rehabilitation programs.

Stability and generalization of combined theory of mind and cognitive remediation interventions in schizophrenia: Follow-up results.

OBJECTIVE: Daily functional impairment is a main target of treatment in schizophrenia. Multiple rehabilitation treatments have been developed to improve patients' sociocognitive and neurocognitive abilities and to generalize the benefits to functioning. However, whether the effects of these treatments can be generalized and maintained remains equivocal. Our study aims to evaluate the stability and generalization of benefits, following combined Theory of Mind (ToM) and cognitive remediation (CR) trainings, compared with an active control group + CR, at a 3-year follow-up. METHOD: Sixty-seven outpatients with schizophrenia who had completed an earlier study of ToM and CR were recruited for a 3-year follow-up assessment. We examined changes in ToM and functioning, at baseline, after treatment, and at follow-up. RESULTS: ANOVAs showed significant Time × Group interactions on ToM and functioning. ANOVAs showed significant differences between groups in effect sizes of ToM and functioning from before treatment to follow-up. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Posttraining ToM improvement was maintained at follow-up, and ToM + CR participants experienced greater functional improvement than participants in the control condition. This study represents the first attempt to report the stability and generalization of treatment effects obtained by combining CR and ToM interventions after 3 years. Combined sociocognitive and neurocognitive treatments can enhance rehabilitation practice for people with schizophrenia to achieve good results on both cognitive and functional outcomes and to maintain positive outcomes.

Daily Functioning in Schizophrenia: Is There Room for Anxiety?

The present study aims at evaluating the impact of anxiety on functional outcome in patients with schizophrenia, also taking into account the other main predictors of functioning identified by literature, to disentangle specific subcomponents which contribute to functional outcome. One hundred five patients with DSM-IV-TR schizophrenia were recruited and underwent a broad functional, psychopathological, and clinical-neuropsychological battery. A forward stepwise regression model was used to assess the predictive effect of anxiety and other factors on daily functioning, showing significant results only for global neurocognitive status and anxiety. These results confirm the role of neurocognition and are also in line with the hypothesis that trait anxiety has a direct impact on functional outcome. Overall, the findings support the role of anxiety as a core feature of schizophrenia pathology, with important implications for both research and clinical settings.

Intellectual and cognitive profiles in patients affected by schizophrenia.

Intellectual abilities display high heterogeneity in patients with schizophrenia that might depend on the interaction among neurodevelopmental processes, environmental factors and neurocognitive decline. This study aimed to disentangle the interplay between intellectual level, cognitive status and each cognitive domain, with a focus on speed-related abilities, also including pre-morbid factors. In details, by means of cluster analysis, we identified both in global sample of 452 patients affected by schizophrenia and in a subsample with high pre-morbid functioning, different profiles based on current intellectual level and global cognitive status, analysing the distribution of deficits in each cognitive domains between groups. Then, through regression models, we analysed the contribution of speed-related domains and global cognitive profile to each other cognitive function. Considering the whole sample, results highlight three groups (high, medium and low cognitive level), while among patients with high pre-morbid level, the heterogeneity was best captured by two groups (high and medium level). Still, within each group, a small to high percentage of patients achieved normal score in neurocognitive abilities depending on the cluster they belong to. Speed of processing and psychomotor coordination resulted impaired in all clusters, even in patients with high pre-morbid functioning. The regression analyses revealed significant effects of both cognitive profile and speed-dependent domains on the other cognitive abilities. This study confirms, in a large sample, previous data about the heterogeneity of intellectual and neurocognitive functioning in schizophrenia and highlights the main role of speed-dependent neurocognitive functioning, also as an important target of rehabilitation.

The role of premorbid adjustment in schizophrenia: Focus on cognitive remediation outcome.

Premorbid adjustment has been associated with several outcomes in schizophrenia and has been proposed as an index of cognitive reserve. This study aims to comprehensively analyse the relation between premorbid adjustment and clinical, neurocognitive, socio-cognitive and functional assessments, as well as to investigate the effect of premorbid adjustment on cognitive improvements after a cognitive remediation therapy protocol. Seventy-nine clinically stabilised outpatients with schizophrenia underwent a combined intervention consisting of cognitive remediation therapy added to standard rehabilitation therapy. All patients were assessed at baseline for psychopathology, premorbid adjustment, intellectual level, cognition and functioning. Cognitive evaluations were also repeated after the intervention. At baseline, significant correlations were observed between premorbid adjustment and working memory. The global cognitive improvement after treatment was significantly predicted by age and premorbid adjustment. This study confirms the association between premorbid adjustment and cognitive impairment and is the first to highlight the possible role of premorbid adjustment on the capacity to recover from cognitive deficits through a cognitive remediation therapy protocol. The data suggest that cognitive remediation may be particularly effective for people in the early course and that the assessment of premorbid adjustment could be of value to design individualised interventions.

From cognitive and clinical substrates to functional profiles: Disentangling heterogeneity in schizophrenia.

The relationship between neurocognition and functioning among patients with schizophrenia is well documented. However, integrating neuropsychological, clinical and psychopathological data to better investigate functional outcome still constitutes a challenge. Artificial neural network-based modeling might help to better capture clinical heterogeneity by analyzing the non-linear relationships among multiple variables. Two hundred and fourteen clinically stabilized patients with schizophrenia were recruited and assessed for neurocognition, psychopathology and functioning. Artificial neural network analyses were conducted to yield significant predictors of functional outcome among clinical and cognitive variables and to build distinct functional Profiles, each characterized by a different medley of cognitive and clinical features. Twenty-two key predictors of daily functioning emerged, encompassing neurocognitive and clinical domains, with major roles for processing speed and attention. Four Profiles were constructed based on specific levels of functioning, each characterized by a distinct distribution of key clinical and neurocognitve measures. This study highlights the importance of a more in-depth investigation of cognitive and clinical heterogeneity. A better understanding of the building blocks of these Profiles would lead to more individualized rehabilitation treatments.

Improving Cognition to Increase Treatment Efficacy in Schizophrenia: Effects of Metabolic Syndrome on Cognitive Remediation's Outcome.

Cognitive impairment, typically more severe in treatment resistant patients, is considered a hallmark of schizophrenia and the prime driver of functional disability. Recent evidence suggests that metabolic syndrome may contribute to cognitive deficits in schizophrenia, possibly through shared underlying mechanisms. However, results are still contradictory and no study has so far examined the influence of metabolic syndrome on cognitive outcome after cognitive remediation therapy (CRT). Based on these premises, this study aims to investigate the relationship between metabolic syndrome and cognition, specifically considering cognitive outcome after treatment. Secondary objectives include the analysis of the association between cognitive impairment and psychopathological status and, in a subgroup of patients, the evaluation of the effect of Sterol Regulatory Element Binding Transcription Factor 1 (SREBF-1) rs11868035 genetic polymorphism, previously associated with metabolic alterations, on both cognition and metabolic syndrome. One-hundred seventy-two outpatients with schizophrenia were assessed for metabolic parameters and neurocognitive measures and 138 patients, who completed CRT, were re-evaluated for cognition. A subsample of 51 patients was also genotyped for rs11868035 from peripheral blood sample. Results show a negative impact of metabolic syndrome on executive functions and global cognitive outcome after CRT. Data also revealed a significant effect of SREBF-1 polymorphism, with a higher prevalence of metabolic syndrome and worse processing speed performance among G/G homozygous subjects, compared the A allele carriers. Overall these findings support the hypothesis that metabolic alterations may hamper the capacity to restore cognitive deficits, as well as they highlight the need to further explore possible converging mechanisms underlying both cognitive and metabolic dysfunction. At the clinical level, results point to the importance of a comprehensive assessment including the metabolic status of patients and of individualized strategies addressing metabolic dysfunction in order to potentiate treatment outcome in schizophrenia.
