Working Memory in Children with Learning Disorders: An EEG Power Spectrum Analysis.

Learning disorders (LDs) are diagnosed in children whose academic skills of reading, writing or mathematics are impaired and lagging according to their age, schooling and intelligence. Children with LDs experience substantial working memory (WM) deficits, even more pronounced if more than one of the academic skills is affected. We compared the task-related electroencephalogram (EEG) power spectral density of children with LDs ( = 23) with a control group of children with good academic achievement ( = 22), during the performance of a WM task.
