Children 6-9 years old were enrolled at Time 1 (T1), with follow-up data obtained?~?18 months later at Time 2 (T2), and?~?36 months later at Time 3 (T3). Findings suggested an initial period of rapid auditory cortex maturation in autism, earlier than TD (prior to and surrounding the T1 exam), followed by a period of faster maturation in TD than autism (T1-T3). As a result of group maturation differences, post-stimulus group differences were observed at T1 but not T3. In contrast, stronger pre-stimulus activity in autism than TD was found at all time points, indicating this brain measure is stable across time.

Research suggests atypical maturation of the peak frequency of resting-state alpha activity (=?PAF) in autism spectrum disorder (ASD). The present study examined resting-state alpha activity in young school-aged children, obtaining magnetoencephalographic (MEG) eyes-closed resting-state data from 47 typically developing (TD) males and 45 ASD males 6.0 to 9.3 years old. Results confirmed a higher PAF in ASD versus TD, and demonstrated that alpha power differences between groups were linked to the shift of PAF in ASD. Additionally, a higher PAF was associated with better cognitive performance in TD but not ASD. Finding thus suggested functional consequences of group differences in resting-state alpha activity.

Social Skills Assessments for Children with Autism Spectrum Disorders / Erin ROTHERAM-FULLER in Autism - Open Access, 3-3 (December 2013)

Langues : Anglais (eng) Mots-clés : Social skills intervention  Autism  Assessment Index. décimale : PER Périodiques Résumé : Several interventions have been developed to address social functioning impairments among children with autism spectrum disorders (ASD). This review evaluated the variety of interventions and outcomes from 59 studies published between 1990 and 2010. Over 80 discrete outcomes were used across the 59 studies, and varied from informal self-report measures to standardized test scores. The types of interventions used were similarly diverse, with the majority (74.6%) using a combination of multiple interventions. Although there is not a standard assessment or intervention that can be recommended to improve social skills, key domains have been identified, which can inform the development of appropriate assessments and interventions to improve the social behaviors of children with ASD.

Parents gave written informed consent and the  children gave verbal and written assent. Index. décimale : PER Périodiques Résumé : We and others have demonstrated the resting-state (RS) peak alpha frequency (PAF) as a potential clinical marker for young children with autism spectrum disorder (ASD), with previous studies observing a higher PAF in school-age children with ASD versus typically developing (TD) children, as well as an association between the RS PAF and measures of processing speed in TD but not ASD. The brain mechanisms associated with these findings are unknown. A few studies have found that in children more mature optic radiation white matter is associated with a higher PAF. Other studies have reported white matter and neural activity associations in TD but not ASD. The present study hypothesized that group differences in the RS PAF are due, in part, to group differences in optic radiation white matter and PAF associations. The maturation of the RS PAF (measured using magnetoencephalography(MEG)), optic radiation white matter (measured using diffusion tensor imaging(DTI)), and associations with processing speed were assessed in a longitudinal cohort of TD and ASD children. Time 1 MEG and DTI measures were obtained at 6-8 years old (59TD and 56ASD) with follow-up brain measures collected?~?1.5 and ~?3 years later. The parietal-occipital PAF increased with age in both groups by 0.13 Hz/year, with a main effect of group showing the expected higher PAF in ASD than TD (an average of 0.26 Hz across the 3 time points). Across age, the RS PAF predicted processing speed in TD but not ASD. Finally, more mature optic radiation white matter measures (FA, RD, MD, AD) were associated with a higher PAF in both groups. Present findings provide additional evidence supporting the use of the RS PAF as a brain marker in children with ASD 6-10 years old, and replicate findings of an association between the RS PAF and processing speed in TD but not ASD. The hypothesis that the RS PAF group differences (with ASD leading TD by about 2 years) would be explained by group differences in optic radiation white matter was not supported, with brain structure-function associations indicating that more mature optic radiation white matter is associated with a higher RS PAF in both groups.
