Analysis of Independent Components for ERPs from ADHD patients of various ages

We investigated the characteristics of independent components for event-related potentials in adolescents (11- 17 years old) and adults (18-30 years old) with attention deficit hyperactivity disorder (ADHD), compared to the normative database. In both age groups was found significant decrease in the amplitude of the two independent components generated (according to sLORETA) in the left posterior temporal and premotor cortex and presumably associated with the processing of visual stimuli and the action suppression. In the teenage group, moreover, was broken component generated in the cingulate cortex in the adult group - another component, the source of which is localized in the premotor cortex.
