Autism spectrum disorder and schizophrenia: An updated conceptual review / Amandeep JUTLA in Autism Research, 15-3 (March 2022)  

Public ISBD [article]  inAutism Research > 15-3 (March 2022) . - p.384-412 Titre : Autism spectrum disorder and schizophrenia: An updated conceptual review Type de document : texte imprimé Auteurs : Amandeep JUTLA, Auteur ; Jennifer H. FOSS-FEIG, Auteur ; Jeremy VEENSTRA-VANDERWEELE, Auteur Article en page(s) : p.384-412 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Autism spectrum disorder (ASD) and schizophrenia (SCZ) are separate disorders, with distinct clinical profiles and natural histories. ASD, typically diagnosed in childhood, is characterized by restricted or repetitive interests or behaviors and impaired social communication, and it tends to have a stable course. SCZ, typically diagnosed in adolescence or adulthood, is characterized by hallucinations and delusions, and tends to be associated with declining function. However, youth with ASD are three to six times more likely to develop SCZ than their neurotypical counterparts, and increasingly, research has shown that ASD and SCZ converge at several levels. We conducted a systematic review of studies since 2013 relevant to understanding this convergence, and present here a narrative synthesis of key findings, which we have organized into four broad categories: symptoms and behavior, perception and cognition, biomarkers, and genetic and environmental risk. We then discuss opportunities for future research into the phenomenology and neurobiology of overlap between ASD and SCZ. Understanding this overlap will allow for researchers, and eventually clinicians, to understand the factors that may make a child with ASD vulnerable to developing SCZ. Lay Summary Autism spectrum disorder and schizophrenia are distinct diagnoses, but people with autism and people with schizophrena share several characteristics. We review recent studies that have examined these areas of overlap, and discuss the kinds of studies we will need to better understand how these disorders are related. Understanding this will be important to help us identify which autistic children are at risk of developing schizophrenia.

Psychotic symptoms in 16p11.2 copy-number variant carriers / Amandeep JUTLA in Autism Research, 13-2 (February 2020)  

Public ISBD [article]  inAutism Research > 13-2 (February 2020) . - p.187-198 Titre : Psychotic symptoms in 16p11.2 copy-number variant carriers Type de document : texte imprimé Auteurs : Amandeep JUTLA, Auteur ; J. Blake TURNER, Auteur ; LeeAnne GREEN SNYDER, Auteur ; Wendy K. CHUNG, Auteur ; Jeremy VEENSTRA-VANDERWEELE, Auteur Article en page(s) : p.187-198 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  chromosome deletion  chromosome duplication  chromosomes  human  obsessive-compulsive disorder  pair 16  phenotype  schizophrenia spectrum and other psychotic disorders Index. décimale : PER Périodiques Résumé : 16p11.2 copy-number variation (CNV) is implicated in neurodevelopmental disorders, with the duplication and deletion associated with autism spectrum disorder (ASD) and the duplication associated with schizophrenia (SCZ). The 16p11.2 CNV may therefore provide insight into the relationship between ASD and SCZ, distinct disorders that co-occur at an elevated rate, and are difficult to distinguish from each other and from common co-occurring diagnoses such as obsessive compulsive disorder (OCD), itself a potential risk factor for SCZ. As psychotic symptoms are core to SCZ but distinct from ASD, we sought to examine their predictors in a population (n = 546) of 16p11.2 CNV carriers and their noncarrier siblings recruited by the Simons Variation in Individuals Project. We hypothesized that psychotic symptoms would be most common in duplication carriers followed by deletion carriers and noncarriers, that an ASD diagnosis would predict psychotic symptoms among CNV carriers, and that OCD symptoms would predict psychotic symptoms among all participants. Using data collected across multiple measures, we identified 19 participants with psychotic symptoms. Logistic regression models adjusting for biological sex, age, and IQ found that 16p11.2 duplication and ASD diagnosis predicted psychotic symptom presence. Our findings suggest that the association between 16p11.2 duplication and psychotic symptoms is independent of ASD diagnosis and that ASD diagnosis and psychotic symptoms may be associated in 16p11.2 CNV carriers. Autism Res 2020, 13: 187-198. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Either deletion or duplication at chromosome 16p11.2 raises the risk of autism spectrum disorder, and duplication, but not deletion, has been reported in schizophrenia (SCZ). In a sample of 16p11.2 deletion and duplication carriers, we found that having the duplication or having an autism diagnosis may increase the risk of psychosis, a key feature of SCZ.

Transgender and gender-diverse autistic adolescents are at elevated risk of depression / Joseph PEREIRA in Autism, 30-2 (February 2026)  

Public ISBD [article]  inAutism > 30-2 (February 2026) . - p.316-328 Titre : Transgender and gender-diverse autistic adolescents are at elevated risk of depression Type de document : texte imprimé Auteurs : Joseph PEREIRA, Auteur ; Natalia RAMOS, Auteur ; LeeAnne Green SNYDER, Auteur ; Jeremy VEENSTRA-VANDERWEELE, Auteur ; Amandeep JUTLA, Auteur Article en page(s) : p.316-328 Langues : Anglais (eng) Mots-clés : autism  clinical  diagnoses  gender  topics Index. décimale : PER Périodiques Résumé : Autistic people are more likely to be transgender and gender diverse than the general population. Furthermore, co-occurring trait-level autism and transgender and gender-diverse identity are associated with symptoms of depression and anxiety, and autistic adolescents who identify as transgender and gender diverse have more internalizing behaviors than both non-transgender and gender-diverse autistic adolescents and non-autistic transgender and gender-diverse adolescents. However, no study has yet examined the extent to which transgender and gender-diverse identity predicts specific co-occurring mental health diagnoses in autistic adolescents. In a sample of 9027 autistic adolescents aged 13 to 17 drawn from the Simons Powering Autism Research for Knowledge cohort, 36 of whom we identified as transgender and gender diverse, we estimated univariate models of transgender and gender-diverse identity as a predictor of individual diagnoses. Depression, but no other diagnosis, remained statistically significant after adjustment for multiple comparisons. In a multiple regression model that incorporated known risk factors for adolescent depression (e.g. language impairment and disturbed sleep), transgender and gender-diverse identity remained a significant predictor (odds ratio: 4.01, 95% confidence interval: 1.87–8.67, p = 5.94 × 10−4) with an effect size at least as strong as that of a depression family history. This suggests transgender and gender-diverse autistic adolescents, who often face stigma and discrimination, are particularly vulnerable to depression.Lay abstract “Transgender and gender diverse” (TGD) people have gender identities that differ from the sex they were assigned at birth. Many autistic people have a TGD identity. Autistic adolescents who are TGD have more “internalizing symptoms,” which include symptoms of depression and anxiety, than autistic adolescents who are not TGD. In this study, we examined a group of 9027 autistic adolescents, 36 of whom had a TGD identity, to determine which, if any, mental health diagnoses would be associated with TGD identity, and whether those associations would remain even after accounting for known risk factors for a diagnosis. We found that depression, but no other diagnosis, was associated with TGD identity. This association remained even when accounting for known risk factors for depression, and in fact, TGD identity was associated with depression at least as strongly as a family history of that diagnosis. This strong association is perhaps not surprising. TGD adolescents often face stigma, social rejection, and discrimination, which can lead to depression. Autistic adolescents can face similar difficulties. Autistic youth who also have a TGD identity may therefore be at particular risk of developing depression. Our study highlights that providers who work with autistic youth in the community should be aware of this risk so they can identify and treat depression when it is present. Future studies should investigate the relationship between depression and TGD identity in autism further, to determine how providers and caregivers can support these youth.
