Physical Anhedonia

Anhedonia, a central dimension within the schizotypy construct, has been considered to be a promising vulnerability marker for schizophrenia-spectrum disorders. The Revised Physical Anhedonia Scale (RPhA) and Revised Social Anhedonia Scale (RSAS) are two self-reports widely used in the assessment of anhedonia; however, they psychometric characteristics have been scarcely investigated in Spanish population. The objective of the current work was to study the psychometric properties of the Revised Physical and Social Anhedonia Scales in non-clinical young adults. The sample was composed of 728 college students with a mean age of 20.1 years (SD=2.5. The data indicated that the scales showed adequate psychometric characteristics. The Cronbach alpha was 0.95 (RSAS) and 0.92 (RPhA) respectively. The confirmatory factor analysis carried out on the matrix of tetrachoric correlations showed that both scales presented an essentially unidimensional solution. The Revised Physical and Social Anhedonia Scales seem to be adequate for psychosis-risk assessment in non-clinical populations. Future research should further investigate the construct validity in other populations and cultures as well as study its relation to emotional aspects and cognitive endophenotypes.

Anhedonia (or hypohedonia) reflects a missing or reduced ability to experience pleasure. Interest in the concept of clinical psychology and psychopathology is due to the high significance of violations of ability to experience pleasure as a predictor of serious mental disorders, such as schizophrenia, depression, chemical dependency. For under- standing the psychological deficits of patients with schizophrenia spectrum disorders is of particular importance to social anhedonia, reflecting the reduced ability to experience interest and pleasure from interactions with socially relevant stimuli and partners, and is implicated in disorders of social cognition, to social exclusion of patients. Revised Social Anhedonia Scale (RSAS) was designed to assess the severity of social anhedonia, tested in many countries, widely used in studies of schizophrenia. The problem of estimating the psychometric characteristics of the test RSAS, including the validity of the technique has become part of the project for the study of social cognition in mental disorders (grant funds of the Russian Science Foundation, Project № 14-18-03461). This article presents the results of the evaluation of the psychometric characteristics of RSAS and the applicability of the methodology for the Russian sample. The study was performed by a grant from the Russian Science Foundation (grant № 14- 18-03461) at the Federal Medical Research Centre of Psychiatry and Narcology under the Ministry of Public Health of the Russian Federation.

Reward And Punishment

Decreased social functioning and high levels of loneliness and social isolation are common in schizophrenia spectrum disorders (SSD), contributing to reduced quality of life. One key contributor to social impairment is low social motivation, which may stem from aberrant neural processing of socially rewarding or punishing stimuli. To summarize research on the neurobiology of social motivation in SSD, we performed a systematic literature review of neuroimaging studies involving the presentation of social stimuli intended to elicit feelings of reward and/or punishment. Across 11 studies meeting criteria, people with SSD demonstrated weaker modulation of brain activity in regions within a proposed social interaction network, including prefrontal, cingulate, and striatal regions, as well as the amygdala and insula. Firm conclusions regarding neural differences in SSD in these regions, as well as connections within networks, are limited due to conceptual and methodological inconsistencies across the available studies. We conclude by making recommendations for the study of social reward and punishment processing in SSD in future research.

Background.Dysregulation of the striatum and altered corticostriatal connectivity have been associated with psychotic disorders. Social anhedonia has been identified as a predictor for the development of schizophrenia spectrum disorders. The aim of the present study was to examine corticostriatal functional connectivity in individuals with high social anhedonia.Method.Twenty-one participants with high social anhedonia score and 30 with low social anhedonia score measured by the Chinese version of the Revised Social Anhedonia Scale were recruited from university undergraduates (age 17–21 years) to undergo resting-state functional MRI scans. Six subdivisions of the striatum in each hemisphere were defined as seeds. Voxel-wise functional connectivity analyses were conducted between each seed and the whole brain voxels, followed by repeated-measures ANOVA for the group effect.Results.Participants with high social anhedonia showed hyper-connectivity between the ventral striatum and the anterior cingulate cortex and the insula, and between the dorsal striatum and the motor cortex. Hypo-connectivity in participants with high social anhedonia was also observed between the ventral striatum and the posterior cingulate cortex. Partial correlation analyses further showed that the functional connectivity between the ventral striatum and the prefrontal cortex was associated with pleasure experience and emotional suppression.Conclusions.Our findings suggest that altered corticostriatal connectivity can be found in participants with high levels of social anhedonia. Since social anhedonia has been considered a predictor for schizophrenia spectrum disorders, our results may provide novel evidence on the early changes in brain functional connectivity in at-risk individuals.

The chapter discusses schizophrenia spectrum disorders (SSDs), including schizophrenia and schizotypal personality disorder (SPD). Schizophrenia and related disorders are part of the broader spectrum of psychosis, a cluster of genetically and phenotypically related conditions marked by loss of contact with external reality. After an overview of these disorders, their developmental features, and the main risk factors identified in the epidemiological literature, the chapter critically reviews existing evolutionary models and suggests new directions for research. The final section applies the criteria developed earlier in the book to classify the disorders within the fast-slow-defense (FSD) model and identify functionally distinct subtypes. The author concludes that most instances of SSDs can be classified as fast spectrum (F-type) conditions; however, there are indications of heterogeneity within these conditions, and future research is likely to identify exceptions to the general pattern.

Abstract The recent renaissance of psychedelic science has reignited interest in the similarity of drug-induced experiences to those more commonly observed in psychiatric contexts such as the schizophrenia-spectrum. This report from a multidisciplinary working group of the International Consortium on Hallucinations Research (ICHR) addresses this issue, putting special emphasis on hallucinatory experiences. We review evidence collected at different scales of understanding, from pharmacology to brain-imaging, phenomenology and anthropology, highlighting similarities and differences between hallucinations under psychedelics and in the schizophrenia-spectrum disorders. Finally, we attempt to integrate these findings using computational approaches and conclude with recommendations for future research.

The Relationship

AbstractSchizophrenia and schizotypal personality disorder share common clinical profiles, neurobiological and genetic substrates along with Prepulse Inhibition and cognitive deficits; among those, executive, attention, and memory dysfunctions are more consistent. Schizotypy is considered to be a non-specific “psychosis-proneness,” and understanding the relationship between schizotypal traits and cognitive function in the general population is a promising approach for endophenotypic research in schizophrenia spectrum disorders. In this review, findings for executive function, attention, memory, and Prepulse Inhibition impairments in psychometrically defined schizotypal subjects have been summarized and compared to schizophrenia patients and their unaffected first-degree relatives. Cognitive flexibility, sustained attention, working memory, and Prepulse Inhibition impairments were consistently reported in high schizotypal subjects in accordance to schizophrenia patients. Genetic studies assessing the effects of various candidate gene polymorphisms in schizotypal traits and cognitive function are promising, further supporting a polygenic mode of inheritance. The implications of the findings, methodological issues, and suggestions for future research are discussed. (JINS, 2012, 18, 1–14)

AbstractBackground:The Bern Psychopathology Scale (BPS) is based on a system-specific approach to classifying the psychopathological symptom pattern of schizophrenia. It consists of subscales for three domains (language, affect and motor behaviour) that are hypothesized to be related to specific brain circuits. The aim of the study was to examine the factor structure of the BPS in patients with schizophrenia spectrum disorders.Methods:One hundred and forty-nine inpatients with schizophrenia spectrum disorders were recruited at the Department of Psychiatry II, Ulm University, Germany (n = 100) and at the University Hospital of Psychiatry, Bern, Switzerland (n = 49). Psychopathology was assessed with the BPS. The VARCLUS procedure of SAS® (a type of oblique component analysis) was used for statistical analysis.Results:Six clusters were identified (inhibited language, inhibited motor behaviour, inhibited affect, disinhibited affect, disinhibited language/motor behaviour, inhibited language/motor behaviour) which explained 40.13% of the total variance of the data. A binary division of attributes into an inhibited and disinhibited cluster was appropriate, although an overlap was found between the language and motor behaviour domains. There was a clear distinction between qualitative and quantitative symptoms.Conclusions:The results argue for the validity of the BPS in identifying subsyndromes of schizophrenia spectrum disorders according to a dimensional approach. Future research should address the longitudinal assessment of dimensional psychopathological symptoms and elucidate the underlying neurobiological processes.

Depressive symptoms commonly occur in individuals with schizophrenia-spectrum disorders. Empirical investigation of this comorbidity has revealed a number of interesting and potentially confusing findings. The purpose of this review is to summarize this literature, focusing on clinical, cognitive, behavioral, phenomenological, and neurobiological processes that are common and potentially disparate to these disorders. Additionally, the review will discuss four depression-related paradoxes that have emerged within the schizophrenia literature. It concludes with a brief summary of treatment considerations for patients with schizophrenia with co-morbid depressive symptoms. It is hoped that this chapter can serve as an organizing framework for future research and can help focus efforts on designing new treatments for ameliorating depression-related symptoms in patients with schizophrenia.
