Titre : Association between schizophrenia and autism spectrum disorder: A systematic review and meta-analysis Type de document : Texte imprimé et/ou numérique Auteurs : Z. ZHENG, Auteur ; P. ZHENG, Auteur ; X. ZOU, Auteur Article en page(s) : p.1110-1119 Langues : Anglais (eng) Mots-clés : association autism spectrum disorder meta-analysis schizophrenia Index. décimale : PER Périodiques Résumé : Schizophrenia and autism spectrum disorder (ASD) are significant public health problems. Scientists have recently explored the association between schizophrenia and ASD, but the findings are inconsistent. Thus, we conducted a systematic review and meta-analysis of epidemiological studies to examine the association between schizophrenia and ASD. PubMed, Embase, and the Cochrane Library were used for literature searches to identify eligible studies published in English before October 2, 2017. Relevant studies estimating the association between schizophrenia and ASD were included. The meta-analysis of the prevalence of schizophrenia in individuals with ASD encompassed 1,950,113 participants and 14,945 individuals with ASD. A random-effects model was chosen to synthesize the effect sizes of individual studies. The prevalence of schizophrenia was significantly higher in individuals with ASD than in controls (odds ratio = 3.55, 95% confidence interval: 2.08-6.05, P < .001). Both sensitivity analysis and publication bias testing revealed that the findings were robust. The systematic review of the prevalence of ASD in individuals with schizophrenia encompassed 930 participants. The prevalence of ASD in individuals with schizophrenia ranged from 3.4 to 52%. The systematic review and meta-analysis showed a significant association between schizophrenia and ASD. Autism Research 2018, 11: 1110-1119. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: This systematic review and meta-analysis explored the association between schizophrenia and ASD. We found that the prevalence of schizophrenia was significantly higher in individuals with ASD than in controls and the prevalence of ASD in individuals with schizophrenia ranged from 3.4 to 52%. A comprehensive estimation of schizophrenia and ASD has important implications for the diagnosis, treatment, prognosis, and development of a fundamental understanding of these disorders.

The extent to which they share common neural substrates remains unclear. Resting-state fMRI data were collected from 35 drug-naïve adolescent participants with first-episode schizophrenia (15.6?±?1.8 years old) and 31 healthy controls (15.4?±?1.6 years old). Data from 22 participants with ASD (13.1?±?3.1 years old) and 21 healthy controls (12.9?±?2.9 years old) were downloaded from the Autism Brain Imaging Data Exchange. Resting-state functional networks were constructed using predefined regions of interest. Multivariate pattern analysis combined with multi-task regression feature selection methods were conducted in two datasets separately. Classification between individuals with disorders and controls was achieved with high accuracy (schizophrenia dataset: accuracy?=?83%; ASD dataset: accuracy?=?80%). Shared atypical brain connections contributing to classification were mostly present in the default mode network (DMN) and salience network (SN). These functional connections were further related to severity of social deficits in ASD (p?=?0.002). Distinct atypical connections were also more related to the DMN and SN, but showed different atypical connectivity patterns between the two disorders. These results suggest some common neural mechanisms contributing to schizophrenia and ASD, and may aid in understanding the pathology of these two neurodevelopmental disorders.

METHODS: One hundred twenty-eight individuals (33 SzO and 46 BpO, considered jointly as 'Familial High Risk' (FHR), and 49 controls) aged 6-17 years underwent clinical, cognitive and neuroimaging assessment at baseline, 2- and 4-year follow-up. Twenty FHR participants (11 SzO and 9 BpO) developed psychotic spectrum symptoms during follow-up, while 59 FHR participants did not. Magnetic resonance imaging was performed on a 3Tesla scanner; cortical surface reconstruction was applied to measure cortical thickness, surface area and grey matter volume. RESULTS: FHR participants who developed psychotic spectrum symptoms over time showed greater time-related mean cortical thinning than those who did not and than controls. By subgroups, this effect was present in both BpO and SzO in the occipital cortex. At baseline, FHR participants who developed psychotic spectrum symptoms over time had smaller total surface area and grey matter volume than those who did not and than controls. Over time, all FHR participants showed less longitudinal decrease in surface area than controls. In those who developed psychotic spectrum symptoms over time, this effect was driven by BpO, while in those who did not, this was due to SzO, who also showed less grey matter volume reduction. CONCLUSION: The emergence of psychotic spectrum symptoms in FHR was indexed by smaller cross-sectional surface area and progressive cortical thinning. Relative preservation of surface area over time may signal different processes according to familial risk. These findings lay the foundation for future studies aimed at stratification of FHR youth.

SASSON, Auteur Article en page(s) : p.1522-1534 Langues : Anglais (eng) Mots-clés : Adult Autism Spectrum Disorder/psychology Autistic Disorder/psychology Cognition Humans Intellectual Disability Male Schizophrenia/complications Social Behavior Social Cognition Young Adult autism spectrum disorders cluster heterogeneity schizophrenia Index. décimale : PER Périodiques Résumé : Autistic adults and those with schizophrenia (SCZ) demonstrate similar levels of reduced social cognitive performance at the group level, but it is unclear whether these patterns are relatively consistent or highly variable within and between the two conditions. Seventy-two adults with SCZ (52 male, M(age) Â =Â 28.2years) and 94 with diagnoses on the autism spectrum (83 male, M(age) Â =Â 24.2years) without intellectual disability completed a comprehensive social cognitive battery. Latent profile analysis identified four homogeneous subgroups that were compared on their diagnosis, independent living skills, neurocognition, and symptomatology. Two groups showed normative performance across most social cognitive tasks but were differentiated by one having significantly higher hostility and blaming biases. Autistic participants were more likely to demonstrate fully normative performance (46.8%) than participants with SCZ, whereas normative performance in SCZ was more likely to co-occur with increased hostility and blaming biases (36.1%). Approximately 43% of participants in the full sample were classified into the remaining two groups showing low or very low performance. These participants tended to perform worse on neurocognitive tests and have lower IQ and fewer independent living skills. The prevalence of low performance on social cognitive tasks was comparable across clinical groups. However, nearly half of autistic participants demonstrated normative social cognitive performance, challenging assumptions that reduced social cognitive performance is inherent to the condition. Subgrouping also revealed a meaningful distinction between the clinical groups: participants with SCZ were more likely to demonstrate hostility biases than autistic participants, even when social cognitive performance was otherwise in the typical range. LAY SUMMARY: Social cognition refers to the perception and interpretation of social information. Previous research has shown that both autistic people and those with schizophrenia demonstrate reduced performance on traditional social cognitive tasks, which we replicate here at the group level. However, we also found that almost half of autistic participants performed in the normal range. Over a third of participants with schizophrenia did as well, but for them this performance was accompanied by a hostility bias not commonly found in the autistic sample. Taken together, findings challenge assumptions that difficulties in social cognition are a uniform characteristic of these clinical conditions in those without intellectual disability.

Knowledge on their mental health is important for prevention and early intervention. METHODS: The authors examined mental disorders and global functioning in children at familial high-risk of schizophrenia (FHR-SZ) and bipolar disorder (FHR-BP) compared with population-based controls. In a longitudinal cohort study, 450 children (FHR-SZ, n=171; FHR-BP, n=104; controls, n=175), were assessed for Axis I disorders at baseline and four-year follow-up (mean age 11.9, SD 0.2) with the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children and for global functioning with Children's Global Assessment Scale. RESULTS: Cumulative incidence of Any Axis I disorder was elevated by age 11 in children at FHR-SZ (54.4%, OR 3.0, 95% CI 1.9-4.7, p<.001) and children at FHR-BP (52.9%, OR 2.8, 95% CI 1.7-4.7, p<.001) compared with controls (28.6%). Children at FHR-SZ and FHR-BP had higher rates of affective disorders (OR 4.4, 95% CI 1.4-13.5, p=.009; OR 5.1, 95% CI 1.6-16.4, p=.007), anxiety disorders (OR 2.1, 95% CI 1.1-4.0, p=.02; OR 3.0, 95% CI 1.5-6.1, p=.002), and stress and adjustment disorders (OR 3.3, 95% CI 1.4-7.5, p=.006; OR 5.3, 95% CI 2.2-12.4, p<.001). Disruptive behavior disorders (OR 2.8, 95% CI 1.0-7.3, p=.04) and ADHD (OR 2.9, 95% CI 1.6-5.3, p<.001) were elevated in children at FHR-SZ. Both FHR groups had lower global functioning than controls. Cumulative incidence of disorders increased equally across the three groups from early childhood to preadolescence and level of functioning did not change differentially. CONCLUSIONS: Children at FHR-SZ and FHR-BP have an elevated prevalence of mental disorders and poorer functioning than controls. Vulnerability in children at FHR manifests early and remains stable throughout childhood. Early attention toward their mental health and identification of those in need of intervention is warranted.
