FREITAG, Auteur Année de publication : 2012 Article en page(s) : p.651–659 Langues : Anglais (eng) Mots-clés : Empathy  autism spectrum disorder  conduct disorder  callous-unemotional traits  development Index. décimale : PER Périodiques Résumé : Background:  A deficit in empathy is discussed to underlie difficulties in social interaction of children with autism spectrum disorder (ASD) and conduct disorder (CD). To date, no study has compared children with ASD and different subtypes of CD to describe disorder-specific empathy profiles in clinical samples. Furthermore, little is known about age influences on the development of empathic skills. The aim of the current study was to compare cognitive and emotional empathy in different age groups of children with ASD, CD with elevated or low callous-unemotional-traits (CU+ vs. CU−) and a matched control group (CG). Methods:  Fifty-five boys with ASD, 36 boys with CD-CU+, 34 boys with CD-CU− and 67 controls were included. The study implemented three tasks on emotion recognition, perspective taking and emotional affection induced by another person’s situation. Multivariate Analysis of variance with the factors group and age (median split) including their interaction term was performed to describe disorder-specific profiles. Results:  Empathy profiles showed differential impairment in children with ASD and CD-CU+. Boys with ASD were impaired in cognitive empathy while participants with CD-CU+ were impaired in emotional empathy. Children with CD-CU− did not differ from the CG. However, boys with CD-CU− were less emotionally reactive in response to film stimuli than children with ASD. Furthermore, we found strong age effects indicating an increase in cognitive and affective empathic skills beyond early infancy in all groups. Conclusions:  In this study, distinct empathic profiles in children with ASD and CD-CU+ were found. Furthermore, the work demonstrates improvement of empathic skills throughout childhood and adolescence, which is comparable for individuals with psychiatric disorders and control children. These results yield implications for further research as well as for therapeutic interventions.

SLC2A3 single-nucleotide polymorphism and duplication influence cognitive processing and population-specific risk for attention-deficit/hyperactivity disorder / Sören MERKER in Journal of Child Psychology and Psychiatry, 58-7 (July 2017)

Our initial genome-wide screening approach for copy number variants (CNVs) in ADHD implicated a duplication of SLC2A3, encoding glucose transporter-3 (GLUT3). GLUT3 plays a critical role in cerebral glucose metabolism, providing energy for the activity of neurons, which, in turn, moderates the excitatory–inhibitory balance impacting both brain development and activity-dependent neural plasticity. We therefore aimed to provide additional genetic and functional evidence for GLUT3 dysfunction in ADHD. Methods Case–control association analyses of SLC2A3 single-nucleotide polymorphisms (SNPs) and CNVs were conducted in several European cohorts of patients with childhood and adult ADHD (SNP, n = 1,886 vs. 1,988; CNV, n = 1,692 vs. 1,721). These studies were complemented by SLC2A3 expression analyses in peripheral cells, functional EEG recordings during neurocognitive tasks, and ratings of food energy content. Results Meta-analysis of all cohorts detected an association of SNP rs12842 with ADHD. While CNV analysis detected a population-specific enrichment of SLC2A3 duplications only in German ADHD patients, the CNV + rs12842 haplotype influenced ADHD risk in both the German and Spanish cohorts. Duplication carriers displayed elevated SLC2A3 mRNA expression in peripheral blood cells and altered event-related potentials reflecting deficits in working memory and cognitive response control, both endophenotypic traits of ADHD, and an underestimation of energy units of high-caloric food. Conclusions Taken together, our results indicate that both common and rare SLC2A3 variation impacting regulation of neuronal glucose utilization and energy homeostasis may result in neurocognitive deficits known to contribute to ADHD risk.
