Spectral Analysis of EEG Differences Between Children With and Without Learning Disabilities

Abstract

Power Spectral Fast Fourier analysis of the scalp EEG was obtained from six locations, three left hemisphere and three right hemisphere, in 69 children with learning disabilities without hyperactivity and 34 control children, during baseline and while performing reading, arithmetical and spatial tasks in their schools. Significant EEG power and percent differences for specific frequencies were obtained between groups. The ability to predict attention deficit or control status was high based upon discriminant analysis for these subjects. The possibility for the supplementation of existing psychometrics with a neurometric based on power analysis of the EEG is discussed.
