چکیده:
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.

Discussion: Our findings showed that the implementation of Neurofeedback sessions improved Theta, which leads to better social communication.
As shown in Figure 1, the theta wave activity (low fre- quency) after Neurofeedback decreased, which could be a sign of improvement.
Figure 2 shows that the gamma waves’ activity (high frequency) after Neurofeedback did not change.
Figure 3 shows that the average of Theta waves was higher than the control in most channels before Neu- rofeedback treatment but after Neurofeedback, these waves decreased.
In Figure 4, the Gamma activities were mostly similar to that of the nor- mal children, and after Neurofeedback, there seems to be no difference between the groups.
In 2007, another study evalu- ated executive functioning of children with ASD after Neurofeedback training using a questionnaire completed by parents and teachers.
This finding shows that although Neurofeedback does not decrease the Gamma, it improves the ASD activity.
Neurofeedback improves executive functioning in children with autism spectrum disorders.
