Abstract:  
The aim of this study was to compare the brain wave pattern of two groups of dyslexic students with perceptual and linguistic type with normal students in reading. Method: In this study, 27 students (24 boys and 3 girls) from first to fifth grade with an average age of 8.16 and a standard deviation of 10.09 years participated. 8 students with perceptual type dyslexia, 10 students with linguistic type dyslexia and 9 normal students with reading were selected by purposive sampling method. Results: After removing noise and artifacts, the data were converted into quantitative digits using Neuroguide software and analyzed using multivariate analysis of variance (MANOVA) and univariate analysis of variance (ANOVA). Based on the results, the linguistic group and the normal group differ in the relative power of the alpha wave in the two channels Fp1 and Fp2, but there is no difference between the three linguistic, perceptual and normal groups in the absolute power of the four waves delta, theta, alpha and beta. Conclusion: The relative power spectrum of alpha band in the forehead can be significantly related to dyslexia problems as seen in the linguistic type.
