Many students with Autism Spectrum Disorder (ASD) struggle to appropriately interact and play with their peers at recess. In this pilot feasibility study, we tested the efficacy of practitioner-implemented, peer-mediated Pivotal Response Training (PRT) with 11 elementary and middle school students with ASD. Participants were randomly assigned to a treatment or control group. We measured outcomes at multiple time points, and analyzed data using multi-level modeling with time nested within student. We demonstrated large and statistically significant increases in peer interaction (d = 1.13). Appropriate play with peers also increased substantially (d = 0.89). Practitioners and students provided positive feedback. These findings suggest school staff can feasibly facilitate peer-implemented PRT that improves social outcomes for students with ASD at recess.

BACKGROUND: Children with developmental disabilities (DD) may experience limited participation in school activities. Little is known about whether school participation of children with DD who attend special schools is impacted. This study specifically focused on physical engagement in school-related activities that require hand use for the comparison between this group of children with DD and typically developing children. METHODS: The sample consisted of 97 children with DD who attended special schools (mean age 8.2 +/- 2.9 years; 60 boys and 37 girls) and 105 typically developing children who attended mainstream schools/kindergartens (mean age 8.6 +/- 2.4 years; 48 boys and 57 girls). Parents completed the Children’s Assessment of Participation with Hands, one of the domains of which captures participation in eight school-related activities involving hand use. RESULTS: Parents of children with DD reported that their children participated less, in terms of the number (chi(2) = 8.45-14.97, P Lien vers le texte intégral (Open Access ou abonnement)

Disrupted neural synchrony may be a primary electrophysiological abnormality in autism spectrum disorders (ASD), altering communication between discrete brain regions and contributing to abnormalities in patterns of connectivity within identified neural networks. Studies exploring brain dynamics to comprehensively characterize and link connectivity to large-scale cortical networks and clinical symptoms are lagging considerably. Patterns of neural coherence within the Default Mode Network (DMN) and Salience Network (SN) during resting state were investigated in 12 children with ASD (MAge = 9.2) and 13 age and gender-matched neurotypicals (NT) (MAge = 9.3) with magnetoencephalography. Coherence between 231 brain region pairs within four frequency bands (theta (4-7 Hz), alpha, (8-12 Hz), beta (13-30 Hz), and gamma (30-80 Hz)) was calculated. Relationships between neural coherence and social functioning were examined. ASD was characterized by lower synchronization across all frequencies, reaching clinical significance in the gamma band. Lower gamma synchrony between fronto-temporo-parietal regions was observed, partially consistent with diminished default mode network (DMN) connectivity. Lower gamma coherence in ASD was evident in cross-hemispheric connections between: angular with inferior/middle frontal; middle temporal with middle/inferior frontal; and within right-hemispheric connections between angular, middle temporal, and inferior/middle frontal cortices. Lower gamma coherence between left angular and left superior frontal, right inferior/middle frontal, and right precuneus and between right angular and inferior/middle frontal cortices was related to lower social/social-communication functioning. Results suggest a pattern of lower gamma band coherence in a subset of regions within the DMN in ASD (angular and middle temporal cortical areas) related to lower social/social-communicative functioning. Autism Res 2017. (c) 2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Communication between different areas of the brain was observed in children with ASD and neurotypical children while awake, but not working on a task. Magnetoencephalography was used to measure tiny magnetic fields naturally generated via brain activity. The brains of children with ASD showed less communication between areas that are important for social information processing compared to the brains of neurotypical children. The amount of communication between these areas was associated with social and social communication difficulties.

The thalamus is a key sensorimotor relay area that is implicated in autism spectrum disorder (ASD). However, it is unknown how the thalamus and white-matter structures that contain thalamo-cortical fiber connections (e.g., the internal capsule) develop from childhood into adulthood and whether this microstructure relates to basic motor challenges in ASD. We used diffusion weighted imaging in a cohort-sequential design to assess longitudinal development of the thalamus, and posterior- and anterior-limbs of the internal capsule (PLIC and ALIC, respectively) in 89 males with ASD and 56 males with typical development (3-41 years; all verbal). Our results showed that the group with ASD exhibited different developmental trajectories of microstructure in all regions, demonstrating childhood group differences that appeared to approach and, in some cases, surpass the typically developing group in adolescence and adulthood. The PLIC (but not ALIC nor thalamus) mediated the relation between age and finger-tapping speed in both groups. Yet, the gap in finger-tapping speed appeared to widen at the same time that the between-group gap in the PLIC appeared to narrow. Overall, these results suggest that childhood group differences in microstructure of the thalamus and PLIC become less robust in adolescence and adulthood. Further, finger-tapping speed appears to be mediated by the PLIC in both groups, but group differences in motor speed that widen during adolescence and adulthood suggest that factors beyond the microstructure of the thalamus and internal capsule may contribute to atypical motor profiles in ASD. Autism Res 2017. (c) 2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Microstructure of the thalamus, a key sensory and motor brain area, appears to develop differently in individuals with autism spectrum disorder (ASD). Microstructure is important because it informs us of the density and organization of different brain tissues. During childhood, thalamic microstructure was distinct in the ASD group compared to the typically developing group. However, these group differences appeared to narrow with age, suggesting that the thalamus continues to dynamically change in ASD into adulthood.

Rates of autism spectrum disorder (ASD) and age at first diagnosis vary considerably across the United States and are moderated by children’s sex, race, ethnicity, and availability of services. We additionally suggest that degree of caregiver-clinician agreement on ASD symptoms may play a role in ASD assessment. Since gold standard ASD assessment integrates caregiver-reported developmental history with clinician observations, differential agreement between reporters across demographic groups may contribute to a host of detrimental outcomes. Here, we investigate whether caregiver-clinician agreement on ASD symptoms varies according to child and family characteristics. Comprehensive data from 2,759 families in the Simons Simplex Collection were analyzed. Linear models were created with caregiver reports predicting clinician reports, and moderating effects of child characteristics and family factors were examined. Poorer reporter correspondence was observed when children had higher IQ scores, stronger adaptive behavior, and more behavioral difficulties. Greater disagreement was also associated with African American racial status (for younger children), lower household income, and paternal social difficulties (for older children). Children’s biological sex did not moderate caregiver-clinician agreement. Marked disagreement between caregivers and clinicians could lead to suboptimal or insufficient intervention services and negative experiences for families throughout development. Such families may also be less likely to qualify for research studies, and therefore be underrepresented in the ASD literature. Modified assessment procedures may be required to improve assessment accuracy and family experiences. Autism Res 2017. (c) 2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Evaluation of autism spectrum disorder (ASD) incorporates both caregiver and clinician perspectives of symptoms, and disagreement between these perspectives could lead to poorer outcomes for families. Using data from 2,759 families, we show that caregiver-clinician agreement on ASD symptoms is poorer for children with higher cognitive and adaptive skills, more behavioral difficulties, lower household income, and African American racial status. These children may be at higher risk for misdiagnosis, poorer family experiences during evaluations, and poorer representation in ASD research.

Autism spectrum disorder (ASD) is a life-long heterogeneous psychiatric disorder, characterized by impaired social interaction and communication, and the presence of repetitive and stereotyped behaviors as well as restricted interests. These features have an impact on the oral health of these individuals: high risk of dental caries, poorer periodontal status, and bruxism are often described. Children with ASD often provide limited collaboration with medical procedures, particularly those considered invasive such as dental care. Children with ASD are prone to agitation, self-injury, and emotional dysregulation; they can also present hypersensitivity to sensory input. These features make it difficult for professionals to examine and treat children with ASD; they interfere with dental care and constitute a barrier to it. Most of them are treated under general anesthesia or sedation. Therefore, children with ASD present a challenge for the dental community. Adapted and specific strategies are required to allow individuals with ASD to go beyond the barriers of dental care. Different tools and techniques of evidence-based practice can be considered: visual pedagogy, behavioral approaches, and numeric devices can be used. Pediatricians have a key role in the oral care of children with autism. The aim of this article is to present the oral health associated with ASD, to set out the possible ways to improve oral health, to enable the practitioner to detect problems, to raise awareness, and to help patients and their families in their care pathway.

It has long been proposed that individuals with autism exhibit a superior processing of details at the expense of an impaired global processing. This theory has received some empirical support, but results are mixed. In this research we have studied local and global processing in ASD and Typically Developing children, with an adaptation of the Navon task, designed to measure congruency effects between local and global stimuli and switching cost between local and global tasks. ASD children showed preserved global processing; however, compared to Typically Developing children, they exhibited more facilitation from congruent local stimuli when they performed the global task. In addition, children with ASD had more switching cost than Typically Developing children only when they switched from the local to the global task, reflecting a specific difficulty to disengage from local stimuli. Together, results suggest that ASD is characterized by a tendency to process local details, they benefit from the processing of local stimuli at the expense of increasing cost to disengage from local stimuli when global processing is needed. Thus, this work demonstrates experimentally the advantages and disadvantages of the increased local processing in children with ASD.

PURPOSE OF REVIEW: Self-injurious behaviour (SIB) is a devastating condition frequently encountered in autism spectrum disorders (ASDs) that can lead to dangerous tissue injury and profound psychosocial difficulty. An increasing number of reports over the past decade have demonstrated the swift and well tolerated resolution of intractable SIB with electroconvulsive therapy (ECT) when psychopharmacological and behavioural interventions are ineffective. The current article provides a review of the salient literature, including the conceptualization of repetitive self-injury along the catatonia spectrum, and further clarifies the critical distinction between ECT and contingent electric shock. RECENT FINDINGS: We searched electronically for literature regarding ECT for self-injurious behaviour from 1982 to present, as the first known report was published in 1982. Eleven reports were identified that presented ECT in the resolution of self-injury in autistic or intellectually disabled patients, and another five reports discussed such in typically developing individuals. These reports and related literature present such self-injury along the spectrum of agitated catatonia, with subsequent implications for ECT. SUMMARY: Intractable self-injury remains a significant challenge in ASDs, especially when patients do not respond adequately to behavioural and psychopharmacological interventions. ECT is well tolerated and efficacious treatment for catatonia, and can confer marked reduction in SIB along the agitated catatonia spectrum.

OBJECTIVE: To develop, implement, and verify the impact of a training program for health care providers working with children with autism spectrum disorder (ASD) in psychosocial care centers for children and adolescents (Centro de Atencao Psicossocial a Infancia e a Adolescencia – CAPSi) in Sao Paulo, Brazil. METHODS: This quasi-experimental study was conducted with 14 professionals from four CAPSi units. The training program consisted of six phases: 1) pre-intervention observation; 2) meeting with staff to assess the main needs of the training program; 3) developing materials for training and evaluation; 4) meetings to discuss program implementation; 5) a final meeting for case discussion and evaluation; and 6) distance supervision. Three measures were used to evaluate the training program: i) the Knowledge, Attitudes, and Practices (KAP) questionnaire; ii) videos containing questions designed to assess program comprehension; and iii) a satisfaction survey. RESULTS: Thirteen videos were produced to as visual aids for use during the training program, and a further 26 videos were developed to evaluate it. The program was well evaluated by the participants. The video responses and KAP questionnaire scores suggest that staff knowledge and attitudes improved after training. CONCLUSION: The positive findings of this study suggest that the tested training program is feasible for use with multidisciplinary teams working in the CAPSi environment.

People with intellectual and developmental disabilities (IDD) vote less frequently than nondisabled people and people with other disabilities. This study explores what factors facilitate and hinder people with IDD’s voting participation. To do so, 1,341 people with IDD were surveyed using the Personal Outcome Measures(R). Binary logistic regressions revealed significant relationships between voting participation, and support needs, residence types, guardianship statuses, and organizational supports. Along with the right supports, attention to barriers that might exist can ensure people with IDD are able to make use of their civil rights and participate in this crucial form of civic engagement.

The number of interventions available for children with autism spectrum disorder (ASD) has expanded greatly in recent years, although relatively little is known about the factors that influence family caregivers as they make treatment decisions for their children. This study involved a statewide survey of parents of young children with ASD to examine the relative weights of the factors that influenced their treatment decisions. Results suggested that caregivers rely on their own intuition for much decision making, although selected professionals are also influential. Implications for professionals working with children with ASD and their families are discussed.

Autism Spectrum Disorders (ASD) are heterogeneous neurodevelopmental disorders with a complex genetic architecture. They are characterized by impaired social communication, stereotyped behaviors and restricted interests and are frequently associated with comorbidities such as intellectual disability, epilepsy and severe sleep disorders. Hyperserotonemia and low melatonin levels are among the most replicated endophenotypes reported in ASD, but their genetic causes remain largely unknown. Based on the biochemical profile of 717 individuals including 213 children with ASD, 128 unaffected siblings and 376 parents and other relatives, we estimated the heritability of whole-blood serotonin, platelet N-acetylserotonin (NAS) and plasma melatonin levels, as well as the two enzymes arylalkylamine N-acetyltransferase (AANAT) and acetylserotonin O-methyltransferase (ASMT) activities measured in platelets. Overall, heritability was higher for NAS (0.72 +/- 0.091) and ASMT (0.59 +/- 0.097) compared with serotonin (0.31 +/- 0.078), AANAT (0.34 +/- 0.077) and melatonin (0.22 +/- 0.071). Bivariate analyses showed high phenotypic and genetic correlations between traits of the second step of the metabolic pathway (NAS, ASMT and melatonin) indicating the contribution of shared genetic factors. A better knowledge of the heritability of the melatonin synthesis variability constitutes an important step to identify the factors that perturb this pathway in individuals with ASD.
