Associations between social cognition, skills, and function and subclinical negative and positive symptoms in 22q11.2 deletion syndrome / A. VANGKILDE in Journal of Neurodevelopmental Disorders, 8-1 (December 2016)
[article]
Titre : Associations between social cognition, skills, and function and subclinical negative and positive symptoms in 22q11.2 deletion syndrome Type de document : Texte imprimé et/ou numérique Auteurs : A. VANGKILDE, Auteur ; Jens Richardt MØLLEGAARD JEPSEN, Auteur ; H. SCHMOCK, Auteur ; C. OLESEN, Auteur ; S. ARNARSDOTTIR, Auteur ; W. F. BAARE, Auteur ; K. J. PLESSEN, Auteur ; M. DIDRIKSEN, Auteur ; H. R. SIEBNER, Auteur ; T. WERGE, Auteur ; L. OLSEN, Auteur Article en page(s) : p.42 Langues : Anglais (eng) Mots-clés : 22q11 deletion syndrome Emotional recognition task Negative symptoms Positive symptoms Schizophrenia Social cognition Social function Social skills Theory of mind Index. décimale : PER Périodiques Résumé : BACKGROUND: Identification of the early signs of schizophrenia would be a major achievement for the early intervention and prevention strategies in psychiatry. Social impairments are defining features of schizophrenia. Impairments of individual layers of social competencies are frequently described in individuals with 22q11.2 deletion syndrome (22q11.2DS), who have high risk of schizophrenia. It is unclear whether and to what extent social impairments associate with subclinical negative and positive symptoms in 22q11.2DS, and which layer of social impairments are more correlated with schizophrenia-related symptoms. The aims of this study were to conduct a comprehensive investigation of social impairments at three different levels (function, skill, and cognition) and their interrelationship and to determine to what degree the social impairments correlate to subclinical levels of negative and positive symptoms, respectively, in a young cohort of 22q11.2DS not diagnosed with schizophrenia. METHODS: The level of social impairment was addressed using questionnaires and objective measures of social functioning (The Adaptive Behavior Assessment System), skills (Social Responsiveness Scale), and cognition (The Awareness of Social Inference Test and CANTAB Emotional Recognition Task), and the presence of subclinical symptoms of schizophrenia were evaluated using the Structured Interview for Prodromal Syndromes in a cross-sectional case-control study of 29 cases and 29 controls, aged 12 to 25 years. Association between social impairment and negative and positive symptoms levels was examined in cases only. RESULTS: Subjects with 22q11.2DS were highly impaired in social function, social skills, and social cognition (p = 6.2 x 10(-9)) relative to control peers and presented with more negative (p = 5.8 x 10(-11)) and positive (p = 7.5 x 10(-4)) symptoms. In particular, social functional and skill levels were highly associated with notably subclinical negative symptoms levels. CONCLUSIONS: This study shows strong correlations between levels of social impairments and subclinical negative and positive symptoms. However, longitudinal studies are required to show if social impairments represent early disease manifestations. If parental or self-reporting suggests severe social impairment, it should advocate for clinical awareness not only to social deficits per se but also of potential subclinical psychosis symptoms.

To identify characteristics of children whose autism spectrum disorder might not be diagnosed during toddlerhood, this study used archived Autism Diagnostic Interview-Revised records to examine the historical presentation of autism spectrum disorder symptoms in 48 school-age children with autism spectrum disorder. Children diagnosed after starting school (Late-Diagnosed; n = 24) were compared to age-matched children diagnosed before school age (Early-Diagnosed; n = 24). Symptom presentation was similar between groups, with the Late-Diagnosed group exhibiting only marginally fewer symptoms historically. The most commonly reported historical symptoms were negative symptoms, namely, deficits in social behaviors. Positive symptoms, such as unusual preoccupations, rituals, and mannerisms, were less commonly reported. These findings may aid earlier identification of autism spectrum disorder in children who would likely be diagnosed at school age.

SCHAER, Auteur ; E. SCARIATI, Auteur ; M. SCHNEIDER, Auteur ; D. VAN DE VILLE, Auteur ; M. DEBBANE, Auteur ; S. ELIEZ, Auteur Article en page(s) : p.23 Langues : Anglais (eng) Mots-clés : Dti Maturation Positive symptoms Resting-state fMRI Schizophrenia Tractography Index. décimale : PER Périodiques Résumé : BACKGROUND: The neural endophenotype associated with 22q11.2 deletion syndrome (22q11DS) includes deviant cortical development and alterations in brain connectivity. Resting-state functional magnetic resonance imaging (fMRI) findings also reported disconnectivity within the default mode network (DMN). In this study, we explored the relationship between functional and structural DMN connectivity and their changes with age in patients with 22q11DS in comparison to control participants. Given previous evidence of an association between DMN disconnectivity and the manifestation of psychotic symptoms, we further investigated this relationship in our group of patients with 22q11DS. METHODS: T1-weighted, diffusion, and resting-state fMRI scans were acquired from 41 patients with 22q11DS and 43 control participants aged 6 to 28 years. A data-driven approach based on independent component analysis (ICA) was used to identify the DMN and to define regions of interest for the structural and functional connectivity analysis. Prodromal psychotic symptoms were assessed in adolescents and adults using the positive symptom scores of the Structured Interview of Prodromal Syndromes (SIPS). Connectivity measures were compared between groups and correlated with age. Repeating the between-group analysis in three different age bins further assessed the presence of age-related alterations in DMN connectivity. Structural and functional connectivity measures were then correlated with the SIPS scores. RESULTS: A simultaneous reduction of functional and structural connectivity between core medial nodes of the DMN was observed. Furthermore, structural connectivity measures significantly increased with age in the control group but not in patients with 22q11DS, suggesting the presence of an age-related alteration of the DMN structural connections. No correlations were found between the DMN disconnectivity and expression of prodromal symptoms in 22q11DS. CONCLUSIONS: These findings indicate the presence of functional and structural DMN disconnectivity in 22q11DS and that patients with 22q11DS fail to develop normal structural connections between medial DMN nodes. This suggests the presence of altered neurodevelopmental trajectories in 22q11DS.
