Public ISBD [article]  inResearch in Autism Spectrum Disorders > 6-3 (July-September 2012) . - p.1000-1003 Titre : Evidence of a faster posterior dominant EEG rhythm in children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Michael D. GREGORY, Auteur ; David E. MANDELBAUM, Auteur Année de publication : 2012 Article en page(s) : p.1000-1003 Langues : Anglais (eng) Mots-clés : Autism  EEG  PDR  Alpha  Posterior dominant rhythm  Autistic disorder  ASD Index. décimale : PER Périodiques Résumé : Multiple electroencephalography (EEG) abnormalities have been associated with autism. In the course of clinical work, we have observed a posterior dominant EEG rhythm at higher frequency in children with autism. To test this observation, 56 EEG tracings of children with autism were compared to the EEGs of age-matched controls. Children with autism showed a posterior dominant EEG rhythm (PDR) of 9.00 Hz versus 8.60 Hz for controls (p = 0.014). This difference was greater at younger ages. Neural correlates of an increased alpha frequency are unclear. This may represent pathology in cortical-thalamic circuits, default mode network, dorsal attention network and/or occipital visual networks. Examination of changes in these circuits in autism may be a worthwhile area for future research.
