With this in mind, we have established a hospital-university-based (HUB) database of autism which incorporates prospective and retrospective data from a large and ethnically diverse population. The collected data includes social-demographic characteristics, standardized behavioral testing, detailed clinical history from electronic patient records, genetic samples, and various neurological measures. We describe the initial cohort characteristics following the first 18 months of data collection (188 children with autism). We believe that the Negev HUB autism database offers a unique and valuable resource for studying the heterogeneity of autism etiologies across different ethnic populations.

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.

Sleep disturbances are associated with specific sensory sensitivities in children with autism / Orna TZISCHINSKY in Molecular Autism, 9 (2018)  

Public ISBD [article]  inMolecular Autism > 9 (2018) . - 22p. Titre : Sleep disturbances are associated with specific sensory sensitivities in children with autism Type de document : texte imprimé Auteurs : Orna TZISCHINSKY, Auteur ; Gal MEIRI, Auteur ; Liora MANELIS, Auteur ; Asif BAR-SINAI, Auteur ; Hagit FLUSSER, Auteur ; Analya MICHAELOVSKI, Auteur ; Orit ZIVAN, Auteur ; Michal ILAN, Auteur ; Michal FAROY, Auteur ; Idan MENASHE, Auteur ; Ilan DINSTEIN, Auteur Article en page(s) : 22p. Langues : Anglais (eng) Mots-clés : Autism  Children  Hypersensitivity towards touch  Sensory abnormalities  Sleep disturbances Index. décimale : PER Périodiques Résumé : Background: Sensory abnormalities and sleep disturbances are highly prevalent in children with autism, but the potential relationship between these two domains has rarely been explored. Understanding such relationships is important for identifying children with autism who exhibit more homogeneous symptoms. Methods: Here, we examined this relationship using the Caregiver Sensory Profile and the Children's Sleep Habits Questionnaire, which were completed by parents of 69 children with autism and 62 age-matched controls. Results: In line with previous studies, children with autism exhibited more severe sensory abnormalities and sleep disturbances than age-matched controls. The sleep disturbance scores were moderately associated with touch and oral sensitivities in the autism group and with touch and vestibular sensitivities in the control group. Hypersensitivity towards touch, in particular, exhibited the strongest relationship with sleep disturbances in the autism group and single-handedly explained 24% of the variance in total sleep disturbance scores. In contrast, sensitivity in other sensory domains such as vision and audition was not associated with sleep quality in either group. Conclusions: While it is often assumed that sensitivities in all sensory domains are similarly associated with sleep problems, our results suggest that hypersensitivity towards touch exhibits the strongest relationship with sleep disturbances when examining children autism. We speculate that hypersensitivity towards touch interferes with sleep onset and maintenance in a considerable number of children with autism who exhibit severe sleep disturbances. This may indicate the existence of a specific sleep disturbance mechanism that is associated with sensitivity to touch, which may be important to consider in future scientific and clinical studies.
