A Brief Study on EEG Signals of Dysgraphia Children in Relaxing and Writing Moods

Background: Electroencephalography (EEG) is the most important tool to study the brain behavior. Therefore, we have investigated the brain signals function of children with learning disabilities (LD) in order to compare the EEG signals during writing and after relaxing with eyes open. Aims: The aim of this work is comparing the brain electrical activity of Dysgraphia children during writing task with their signal during the rest condition. Materials and Methods: This used method in this work based on power spectral density (PSD) proposed with Welch. Participants in this work were included 6 girls and 10 boys with age of 9.2±0.64 who have Dysgraphia disorder. Results: The results show that a frequency ratio of writhing mode is more than resting mode. It is also indicated that the brain signals during writhing are more complex for Dysgraphia children. Conclusion: Our results reveal that insufficient maturity of the brain increase during writing rather than relaxing mode. Finally, to overcome the LD situation Neurofeedback can be proposed.
