Quantitative EEG Features For Characterizing Autistic Spectrum Disorder

1. BackgroundAutism or autistic spectrum disorders (ASD) is a complex neurodevelopmental disorder, which described by impairments in social interactions, insufficiencies in verbal and nonverbal communication and stereotyped, repetitive behaviors and interests. The aim of the present study was investigating quantitative electroencephalographic (QEEG) profile for children with autistic spectrum disorder (ASD). 2. MethodFive-minute QEEG data were obtained from 10 normal controls (NCs) and 10 children with ASD. 3. Results Outcomes for Q-EEG displays increased delta-theta activity in frontal lobe of brain. results revealed that ASD children showed significantly less relative alpha than NC , and also children with ASD show over focused/ over aroused pattern in high Beta. these investigation revealed that ASD have troubles of neural connectivity. 4. ConclusionsChildren with neurological and developmental disorders such as ASD shows generally increased delta-theta activity and over focused pattern in high Beta but less Alpha power which is linked to poor cognitive abilities. Prognosis of ASD depends on the intellectual capacities.
