![عکس صفحه اول مقاله: Evidence of a faster posterior dominant EEG rhythm in children with autism Evidence of a faster posterior dominant EEG rhythm in children with autism](/preview/png/370610.png)
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.
► We examined the EEG PDR in children with autism and age-matched controls.
► Children with autism displayed a significantly faster PDR compared with controls.
► This finding may indicate pathology in resting neural networks of the autistic brain.
