An intranasal herbal medicine improves executive functions and activates the underlying neural network in children with autism / Agnes S. CHAN in Research in Autism Spectrum Disorders, 8-6 (June 2014)
[article]
Titre : An intranasal herbal medicine improves executive functions and activates the underlying neural network in children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Agnes S. CHAN, Auteur ; Sophia L. SZE, Auteur ; Yvonne M.Y. HAN, Auteur Article en page(s) : p.681-691 Langues : Anglais (eng) Mots-clés : Autism Herbal medicine Executive functions EEG Prefrontal Anterior cingulate Index. décimale : PER Périodiques Résumé : Our animal and human studies have provided empirical evidence that a patented intranasal herbal medicine alters brain functions and neurophysiology. In particular, it reduces clinical symptoms and immunological anomalies in children with autism spectrum disorders (ASD). The present study explored whether the herbal formula can improve executive functions and the associated neuroelectrophysiological activity in ASD. Thirty children with ASD were evenly assigned to receive a daily intranasal administration of the herbal formula or no treatment. Their executive functions, behavioral problems, and electroencephalographic activity during an executive control task were measured before and after six months of treatment with the herbal formula. After treatment, the experimental group showed significantly improved inhibitory control, mental flexibility, and planning, which coincided with an event-related elevation in the activity of their prefrontal and anterior cingulate cortices (regions that are critical for executive control of behaviors) as well as reduced daily dysexecutive behaviors. In contrast, the control group showed no significant changes in executive functions or neural system activity. These findings support the administration of the intranasal herbal medicine as a possible intervention for improving executive functions in ASD.

Titre : Adolescent daytime sleepiness as a risk factor for adult crime Type de document : Texte imprimé et/ou numérique Auteurs : Adrian RAINE, Auteur ; Peter H. VENABLES, Auteur Article en page(s) : p.728-735 Langues : Anglais (eng) Mots-clés : Sleepiness sleep antisocial crime attention electroencephalogram prefrontal adolescence adversity intervention Index. décimale : PER Périodiques Résumé : Background While recent cross-sectional research has documented a relationship between sleep problems and antisocial behavior, the longitudinal nature of this relationship is unknown. This study tests both the hypothesis that adolescent daytime sleepiness is associated with later adult criminal offending, and also tests a biopsychosocial mediation model in which social adversity predisposes to sleepiness, which in turn predisposes to attentional impairment, and to adult crime. Methods Schoolboys aged 15 years rated themselves on self-report sleepiness. Age 15 antisocial behavior was assessed by teacher ratings and self-reports, while convictions for crime were assessed at age 29. Attentional capacity at age 15 was assessed by autonomic orienting, with arousal assessed by the electroencephalogram (EEG). Results Sleepy adolescents were more likely to be antisocial during adolescence, and were 4.5 times more likely to commit crime by age 29. The sleepiness–adult crime relationship withstood control for adolescent antisocial behavior. Self-report sleepiness predicted to adult crime over and above objective measures of daytime sleepiness (EEG theta activity) and age 15 antisocial behavior. Poor daytime attention partly mediated the sleep–crime relationship. Mediation analyses also showed that social adversity predisposed to daytime sleepiness which was associated with reduced attention which in turn predisposed to adult crime. Conclusions Findings are the first to document a longitudinal association between sleepiness in adolescence and crime in adulthood. The longitudinal nature of this relationship, controlling for age 15 antisocial behavior, is consistent with the hypothesis that adolescent sleepiness predisposes to later antisociality. Findings are also consistent with the notion that the well-established link between social adversity and adult crime is partly explained by sleepiness. Results suggest that a very brief and simple assessment of subjective daytime sleepiness may have prognostic clinical value, and that interventions to reduced sleepiness could be a useful avenue for future crime prevention.

HAAK, Auteur Article en page(s) : p.572-582 Langues : Anglais (eng) Mots-clés : Amygdala Autism spectrum disorder Functional connectivity Parcellation Prefrontal Index. décimale : PER Périodiques Résumé : Amygdala dysfunction plays a role in the social impairments in autism spectrum disorders (ASD), but it is unclear which of its subregions are abnormal in ASD. This study compared the volume and functional connectivity (FC) strength of three FC-defined amygdala subregions between ASD and controls, and assessed their relation to social skills in ASD. A subregion associated with the social perception network was enlarged in ASD (F1 = 7.842, p = .008) and its volume correlated significantly with symptom severity (social skills: r = .548, p = .009). Posthoc analysis revealed that the enlargement was driven by the vmPFC amygdala network. These findings refine our understanding of abnormal amygdala connectivity in ASD and may inform future strategies for therapeutic interventions targeting the amygdalofrontal pathway.
