the effect of neurofeedback on brain waves in children with autism spectrum disorders

objectives: autism spectrum disorder (asd) is a group of neurodevelopment syndromes with impairments in social communications and restrictive or repetitive behaviors. neurofeedback is a new method that may regulate neuro and metabolic function in brain. this study is semi-experimental, with pre and post test.  methods: in 26 children with asd, 40 sessions of neurofeedback were done. brain waves were recorded before and after intervention by eeg/erp 19 channels.  results: the average of theta (low frequency) power decreased, but there was no difference in the gamma of gamma waves (high frequency).  discussion: our findings showed that the implementation of neurofeedback sessions improved theta, which leads to better social communication.
