Risk for ASD in Preterm Infants: A Three-Year Follow-Up Study / Ayelet HAREL-GADASSI in Autism Research and Treatment, 2018 (2018)  

Public ISBD [article]  inAutism Research and Treatment > 2018 (2018) . - 9p. Titre : Risk for ASD in Preterm Infants: A Three-Year Follow-Up Study Type de document : Texte imprimé et/ou numérique Auteurs : Ayelet HAREL-GADASSI, Auteur ; Edwa FRIEDLANDER, Auteur ; Maya YAARI, Auteur ; Benjamin BAR-OZ, Auteur ; Smadar EVENTOV-FRIEDMAN, Auteur ; David MANKUTA, Auteur ; Nurit YIRMIYA, Auteur Article en page(s) : 9p. Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : BACKGROUND: The aim of this study was to examine the long-term risk for autism spectrum disorders (ASD) in individuals who are born preterm and full-term using both observational instruments and parental reports. Neonatal risk factors and developmental characteristics associated with ASD risk were also examined. METHOD: Participants included 110 preterm children (born at a gestational age of ? 34 weeks) and 39 full-term children assessed at ages 18, 24, and 36 months. The Autism Diagnostic Observation Schedule, the Modified Checklist for Autism in Toddlers, the Autism Diagnostic Interview-Revised, the Social Communication Questionnaire, and the Mullen Scales of Early Learning were administered. RESULTS AND CONCLUSIONS: The long-term risk for ASD was higher when parental reports were employed compared to observational instruments. At 18 and 24 months, a higher long-term risk for ASD was found for preterm children compared to full-term children. At 36 months, only one preterm child and one full-term child met the cutoff for ASD based on the ADOS, yet clinical judgment and parental reports supported an ASD diagnosis for the preterm child only. Earlier gestational age and lower general developmental abilities were associated with elevated ASD risk among preterm children.

Neuromagnetic Beta-Band Oscillations during Motor Imitation in Youth with Autism / I. BUARD in Autism Research and Treatment, 2018 (2018)  

Public ISBD [article]  inAutism Research and Treatment > 2018 (2018) . - 12p. Titre : Neuromagnetic Beta-Band Oscillations during Motor Imitation in Youth with Autism Type de document : Texte imprimé et/ou numérique Auteurs : I. BUARD, Auteur ; E. KRONBERG, Auteur ; S. STEINMETZ, Auteur ; S. HEPBURN, Auteur ; D. C. ROJAS, Auteur Article en page(s) : 12p. Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Children with ASD often exhibit early difficulties with action imitation, possibly due to low-level sensory or motor impairments. Impaired cortical rhythms have been demonstrated in adults with ASD during motor imitation. While those oscillations reflect an age-dependent process, they have not been fully investigated in youth with ASD. We collected magnetoencephalography data to examine patterns of oscillatory activity in the mu (8-13 Hz) and beta frequency (15-30 Hz) range in 14 adolescents with and 14 adolescents without ASD during a fine motor imitation task. Typically developing adolescents exhibited adult-like patterns of motor signals, e.g., event-related beta and mu desynchronization (ERD) before and during the movement and a postmovement beta rebound (PMBR) after the movement. In contrast, those with ASD exhibited stronger beta and mu-ERD and reduced PMBR. Behavioral performance was similar between groups despite differences in motor cortical oscillations. Finally, we observed age-related increases in PBMR and beta-ERD in the typically developing children, but this correlation was not present in the autism group. These results suggest reduced inhibitory drive in cortical rhythms in youth with autism during intact motor imitation. Furthermore, impairments in motor brain signals in autism may not be due to delayed brain development. In the context of the excitation-inhibition imbalance perspectives of autism, we offer new insights into altered organization of neurophysiological networks.

Role of Inner Speech on Serial Recall in Children with ASD: A Pilot Study Using the Luria Hand Test / Shota MITSUHASHI in Autism Research and Treatment, 2018 (2018)  

Public ISBD [article]  inAutism Research and Treatment > 2018 (2018) . - 7p. Titre : Role of Inner Speech on Serial Recall in Children with ASD: A Pilot Study Using the Luria Hand Test Type de document : Texte imprimé et/ou numérique Auteurs : Shota MITSUHASHI, Auteur ; Shogo HIRATA, Auteur ; Hideyuki OKUZUMI, Auteur Article en page(s) : 7p. Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This study was conducted to investigate the relation between the effect of articulatory suppression on the serial recall and severity of social impairments among children with autism spectrum disorders (ASD). The Luria hand test (LHT) was administered to evaluate the capacity for serial recall in 13 children with ASD. The LHT was administered under three conditions: control, under articulatory suppression, and under spatial suppression. Performance on the LHT of children with ASD was significantly lower in terms of both articulatory suppression and the spatial suppression condition. Moreover, the severity of social impairment in children with ASD was related to individual differences of effects of articulatory suppression on the LHT, but not with effects of spatial suppression. These results support the notion that dialogic inner speech which mediates complex cognitive abilities has inherently social origins.

A Study of the Correlation between VEP and Clinical Severity in Children with Autism Spectrum Disorder / Winai SAYORWAN in Autism Research and Treatment, 2018 (2018)  

Public ISBD [article]  inAutism Research and Treatment > 2018 (2018) . - 8p. Titre : A Study of the Correlation between VEP and Clinical Severity in Children with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Winai SAYORWAN, Auteur ; Nutthida PHIANCHANA, Auteur ; Kannika PERMPOONPUTTANA, Auteur ; Vorasith SIRIPORNPANICH, Auteur Article en page(s) : 8p. Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Visual evoked potential (VEP) is a technique used to assess the brain's electrical response to visual stimuli. The aims of this study were to examine neural transmission within the visual pathway through VEP testing in preschool children with autism spectrum disorder (ASD) and compare it to age-matched controls, as well as search for a correlation between the VEP parameters and the symptoms of ASD. Participants were composed of ASD children (9 males) and typically developing children (8 males and 4 females), aged between 3 and 5 years. Checkerboards were chosen as the pattern-reversal VEP. The clinical severity of ASD was assessed using the Autism Treatment Evaluation Checklist (ATEC) and the Vineland Adaptive Behavior Scales 2nd edition (VABS-II). Our findings demonstrated that children with ASD had significantly longer N145 latency compared to the controls. A longer N145 latency correlated with a higher score of ATEC within the sensory/cognitive awareness subdomain. In addition, a slower N145 response was also associated with a lower VABS-II score within the socialization domain. The correlation between longer VEP latency and abnormal behaviors in children with ASD suggests a delayed neural communication within other neural circuits, apart from the visual pathway. These lines of evidence support the possibility of using VEP, along with clinical parameters, for the assessment of ASD severity.
