The study compared SCIT-A participants (n?=?20) to participants with ASD who received treatment as usual (TAU; n?=?21). Overall, increased visual attention to faces and background objects and decreased attention to hands playing with toys at baseline were associated with improved social functioning immediately following intervention, suggesting this eye tracking task may reliably predict ASD social intervention outcomes.

We examined the prevalence of youth meeting ADHD criteria on the ADHD rating scale fourth edition (ADHD-RS-IV), the relationship of ADHD-RS-IV ratings with participant characteristics and behaviors, and its underlying factor structure in 386, 7–17 year olds with ASD without intellectual disability. Expected parent prevalence rates, relationships with age and externalizing behaviors were observed, but confirmatory factor analyses revealed unsatisfactory fits for one-, two-, three-factor models. Exploratory analyses revealed several items cross-loading on multiple factors. Implications of screening ADHD in youth with ASD using current diagnostic criteria are discussed.

Titre : Evidence against the "normalization" prediction of the early brain overgrowth hypothesis of autism Type de document : Texte imprimé et/ou numérique Auteurs : Lisa D. YANKOWITZ, Auteur ; John D. HERRINGTON, Auteur ; Benjamin E YERYS, Auteur ; Joseph A. PEREIRA, Auteur ; Juhi PANDEY, Auteur ; Robert T. SCHULTZ, Auteur Année de publication : 2020 Article en page(s) : 51 p. Langues : Anglais (eng) Mots-clés : Adolescent Autism Brain volume Iq Mri Structural imaging Index. décimale : PER Périodiques Résumé : BACKGROUND: The frequently cited Early Overgrowth Hypothesis of autism spectrum disorder (ASD) postulates that there is overgrowth of the brain in the first 2 years of life, which is followed by a period of arrested growth leading to normalized brain volume in late childhood and beyond. While there is consistent evidence for early brain overgrowth, there is mixed evidence for normalization of brain volume by middle childhood. The outcome of this debate is important to understanding the etiology and neurodevelopmental trajectories of ASD. METHODS: Brain volume was examined in two very large single-site samples of children, adolescents, and adults. The primary sample comprised 456 6-25-year-olds (ASD n = 240, typically developing controls (TDC) n = 216), including a large number of females (n = 102) and spanning a wide IQ range (47-158). The replication sample included 175 males. High-resolution T1-weighted anatomical MRI images were examined for group differences in total brain, cerebellar, ventricular, gray, and white matter volumes. RESULTS: The ASD group had significantly larger total brain, cerebellar, gray matter, white matter, and lateral ventricular volumes in both samples, indicating that brain volume remains enlarged through young adulthood, rather than normalizing. There were no significant age or sex interactions with diagnosis in these measures. However, a significant diagnosis-by-IQ interaction was detected in the larger sample, such that increased brain volume was related to higher IQ in the TDCs, but not in the ASD group. Regions-of-significance analysis indicated that total brain volume was larger in ASD than TDC for individuals with IQ less than 115, providing a potential explanation for prior inconsistent brain size results. No relationships were found between brain volume and measures of autism symptom severity within the ASD group. LIMITATIONS: Our cross-sectional sample may not reflect individual changes over time in brain volume and cannot quantify potential changes in volume prior to age 6. CONCLUSIONS: These findings challenge the "normalization" prediction of the brain overgrowth hypothesis by demonstrating that brain enlargement persists across childhood into early adulthood. The findings raise questions about the clinical implications of brain enlargement, since we find that it neither confers cognitive benefits nor predicts increased symptom severity in ASD.

[article]
Titre : Fine-motor skill deficits in childhood predict adulthood tic severity and global psychosocial functioning in Tourette's syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Michael H. BLOCH, Auteur ; James F. LECKMAN, Auteur ; Denis G. SUKHODOLSKY, Auteur ; Robert T. SCHULTZ, Auteur Année de publication : 2006 Article en page(s) : p.551–559 Langues : Anglais (eng) Mots-clés : Tourette's-syndrome obsessive-compulsive-disorder motor-skills neuropsychology Index. décimale : PER Périodiques Résumé : Background: Most children with Tourette's syndrome (TS) experience a significant decline in tic symptoms during adolescence. Currently no clinical measures have been identified that can predict whose tic symptoms will persist into adulthood. Patients with TS have deficits on neuropsychological tests involving fine-motor coordination and visual-motor integration. We seek to determine if these neuropsychological tests are useful in predicting future symptom severity.
Methods: Thirty-two children, aged 8–14, with TS underwent clinical evaluation and a focused neuropsychological testing battery consisting of the Purdue Pegboard, Beery Visual-Motor Integration (VMI) Test and the Rey-Osterreith Complex Figure Task (RCFT). A follow-up clinical assessment was performed on these children an average of 7.5 years later. Ordinal logistic regression analysis was used to correlate neuropsychological testing at Time 1 with tic severity, OCD severity and global psychosocial functioning at Time 2.
Results: Poor performance with the dominant hand on the Purdue Pegboard test predicted worse adulthood tic severity and correlated with tic severity at the time of childhood assessment. Poor performance on the VMI and Purdue Pegboard tests (both dominant and non-dominant hand) also predicted worse adulthood global psychosocial functioning. None of the neuropsychological tests were useful in predicting the future course of OCD symptoms in TS patients.
Conclusion: Fine motor skill deficits may be a predictor of future tic severity and global psychosocial function in children with TS. We hypothesize that performance on the Purdue Pegboard test may serve as a useful endophenotype in the study of TS and provide a rough measure of the degree of basal ganglia dysfunction present in TS patients.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2005.01561.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=739
