Benign External Hydrocephalus in a Subgroup of Autistic Children Prior to Autism Diagnosis / Gal BEN-ARIE in Autism Research, 18-9 (September 2025)  

Public ISBD [article]  inAutism Research > 18-9 (September 2025) . - p.1796-1804 Titre : Benign External Hydrocephalus in a Subgroup of Autistic Children Prior to Autism Diagnosis Type de document : texte imprimé Auteurs : Gal BEN-ARIE, Auteur ; Ilan SHELEF, Auteur ; Gal MEIRI, Auteur ; Idan MENASHE, Auteur ; Ilan DINSTEIN, Auteur ; Ayelet ARAZI, Auteur Article en page(s) : p.1796-1804 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  benign external hydrocephalus  CSF  extra-axial cerebrospinal fluid  MRI Index. décimale : PER Périodiques Résumé : ABSTRACT Benign external hydrocephalus (BEH) is evident in < 0.6% of births. It is defined by abnormally large cerebrospinal fluid (CSF) volumes in the subarachnoid space (SAS) and otherwise normal neuroimaging findings before 2 years of age. BEH has not been associated with specific developmental disorders and is not treated because it usually resolves spontaneously. However, quantitative MRI studies have reported that some toddlers with autism exhibit enlarged extra-axial CSF (EA-CSF) volumes. Our objective was to determine whether a subgroup of children with autism exhibits both qualitative BEH and quantitative EA-CSF volume enlargements. We analyzed clinical brain MRI scans in a retrospective sample of 136 children, 5 99 months old, 83 with autism, who were assessed for BEH by neuroradiologists. EA-CSF volume and total cerebral volume (TCV) were quantified in T2-weighted scans by manual labeling. Measures were compared across groups while stratifying participants by age. Neuroradiologists reported BEH findings in 33% of autistic children scanned before the age of 2 years old (i.e., before autism diagnosis). Quantitative MRI analyses demonstrated that autistic children in this age group exhibited significantly larger EA-CSF volumes relative to controls (t (49)=2.89, p=0.006, Cohen's d=0.82) with 30% of autistic children and 9.5% of the controls exhibiting EA-CSF/TCV ratios > 0.14, a previously suggested threshold of potential clinical relevance. EA-CSF differences were not apparent in older children. The prevalence of BEH associated with quantifiable EA-CSF enlargements was remarkably high in toddlers who later developed autism, suggesting a specific autism etiology involving early transient CSF circulation problems with potentially long-lasting neurodevelopmental impact.

Children with autism exhibit similar longitudinal changes in core symptoms when placed in special or mainstream education settings / Michal ILAN in Autism, 27-6 (August 2023)  

Public ISBD [article]  inAutism > 27-6 (August 2023) . - p.1628-1640 Titre : Children with autism exhibit similar longitudinal changes in core symptoms when placed in special or mainstream education settings Type de document : texte imprimé Auteurs : Michal ILAN, Auteur ; Michal FAROY, Auteur ; Ditza ZACHOR, Auteur ; Liora MANELIS, Auteur ; Danel WAISSENGREEN, Auteur ; Analya MICHAELOVSKI, Auteur ; Inbar AVNI, Auteur ; Idan MENASHE, Auteur ; Judah KOLLER, Auteur ; Ilan DINSTEIN, Auteur ; Gal MEIRI, Auteur Article en page(s) : p.1628-1640 Langues : Anglais (eng) Mots-clés : autism spectrum disorders;core symptoms;education services;inclusion;mainstream education;preschool children;special education Index. décimale : PER Périodiques Résumé : Children with autism spectrum disorder (ASD) are often placed in inclusive mainstream education (ME) or exclusive special education (SE) settings. While ME settings usually offer less-intensive and structured intervention programs than SE settings, they offer more exposure to typically developing peers. A total of 121 children (2-5 years old) with ASD, 85 in SE and 36 in ME, completed two Autism Diagnostic Observation Schedule, 2nd edition (ADOS-2) assessments. Repeated-measures analysis of covariance (ANCOVA) analyses were used to assess longitudinal changes in ADOS-2 calibrated severity scores (CSS) and language production (estimated from the ADOS-2), while accounting for baseline cognitive scores, age of diagnosis, and parent-reported intensity of intervention. Longitudinal changes in ADOS CSS did not differ significantly across educational settings but were strongly associated with the age of diagnosis, demonstrating that children diagnosed earlier improved more regardless of educational settings. These findings suggest that children with ASD placed in SE and ME exhibit similar longitudinal changes in core ASD symptoms. Further studies comparing additional outcome measures such as cognitive abilities and adaptive behaviors are highly warranted for establishing placement recommendations and public health policies.Lay abstractToday, children with autism spectrum disorder (ASD) are placed in mainstream or special education settings somewhat arbitrarily with no clear clinical recommendations. Here, we compared changes in core ASD symptoms, as measured by the Autism Diagnostic Observation Schedule, 2nd edition (ADOS-2) clinical assessment, across ASD preschool children placed in special or mainstream education. Longitudinal changes in ADOS-2 scores did not differ significantly across settings over a 1- to 2-year period. While some children improved in core ASD symptoms, others deteriorated in both settings. This highlights the need to identify specific criteria for establishing meaningful placement recommendations.

Children with autism observe social interactions in an idiosyncratic manner / Inbar AVNI in Autism Research, 13-6 (June 2020)  

Public ISBD [article]  inAutism Research > 13-6 (June 2020) . - p.935-946 Titre : Children with autism observe social interactions in an idiosyncratic manner Type de document : texte imprimé Auteurs : Inbar AVNI, Auteur ; Gal MEIRI, Auteur ; Asif BAR-SINAI, Auteur ; Doron REBOH, Auteur ; Liora MANELIS, Auteur ; Hagit FLUSSER, Auteur ; Analya MICHAELOVSKI, Auteur ; Idan MENASHE, Auteur ; Ilan DINSTEIN, Auteur Article en page(s) : p.935-946 Langues : Anglais (eng) Mots-clés : ecological  eye position  eye tracking  gaze  idiosyncrasy  movies  naturalistic  outcome measure  social  symptom severity  variability Index. décimale : PER Périodiques Résumé : Previous eye-tracking studies have reported that children with autism spectrum disorders (ASD) fixate less on faces in comparison to controls. To properly understand social interactions, however, children must gaze not only at faces but also at actions, gestures, body movements, contextual details, and objects, thereby creating specific gaze patterns when observing specific social interactions. We presented three different movies with social interactions to 111 children (71 with ASD) who watched each of the movies twice. Typically developing children viewed the movies in a remarkably predictable and reproducible manner, exhibiting gaze patterns that were similar to the mean gaze pattern of other controls, with strong correlations across individuals (intersubject correlations) and across movie presentations (intra-subject correlations). In contrast, children with ASD exhibited significantly more variable/idiosyncratic gaze patterns that differed from the mean gaze pattern of controls and were weakly correlated across individuals and presentations. Most importantly, quantification of gaze idiosyncrasy in individual children enabled separation of ASD and control children with higher sensitivity and specificity than traditional measures such as time gazing at faces. Individual magnitudes of gaze idiosyncrasy were also significantly correlated with ASD severity and cognitive scores and were significantly correlated across movies and movie presentations, demonstrating clinical sensitivity and reliability. These results suggest that gaze idiosyncrasy is a potent behavioral abnormality that characterizes a considerable number of children with ASD and may contribute to their impaired development. Quantification of gaze idiosyncrasy in individual children may aid in assessing symptom severity and their change in response to treatments.

LAY SUMMARY: Typically, developing children watch movies of social interactions in a reliable and predictable manner, attending faces, gestures, actions, body movements, and objects that are relevant to the social interaction and its narrative. Here, we demonstrate that children with ASD watch such movies with significantly more variable/idiosyncratic gaze patterns that differ across individuals and across movie presentations. We demonstrate that quantifying this gaze variability may aid in identifying children with ASD and in determining the severity of their symptoms.

We explore the robustness of this finding with a new sample of high-functioning adults with autism. Participants were presented with visual, somatosensory and auditory stimuli in the scanner whilst they completed a one-back task. While ASD and control participants were statistically indistinguishable with respect to behavioral responses, the new ASD group exhibited greater IIV relative to controls. We also show that the IIV was equivalent across hemispheres and remained stable over the duration of the experiment. This suggests that greater cortical IIV may be a replicable characteristic of sensory systems in autism.
