BACKGROUND AND AIMS: Attention Deficit/Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental disorders affecting approximately 5% of children and teenagers population. ADHD is characterized by developmentally inappropriate levels of inattention, impulsivity and overactivity. The aim of this study was to investigate attentional processes and their electrophysiological correlates in children and teenagers with ADHD diagnosis. METHODS: Fifty ADHD children and teenagers and 50 age-, and sex-matched healthy controls participated in this study. Participants performed Attention Network Test (ANT, Fan et al. 2002) – paradigm combining cue detection (Posner 1980) with flanker-type paradigm (Eriksen and Eriksen 1974). ANT allows for the behavioral assessment of different attention functions – alerting, orienting, and executive functions. During task performance EEG data were collected using 64 channel EGI Geodesic System. Measures of attention evaluated in attentional test were analyzed in terms of relation to EEG recording results. RESULTS: The results obtained on behavioral level revealed significant differences in ANT performance in above mentioned groups. ADHD participants, when compared with healthy controls, were less accurate and had longer reaction times in the condition evaluating executive attention. We have also found different patterns of Event Related Potentials (ERPs) related to ANT performance in these groups. Results of ERPs calculated for parietal electrodes cluster revealed that P300 amplitude was lower in ADHD group in comparison with controls. CONCLUSIONS: The results of EEG recordings suggest worse allocation of attention resources which may result in deficits in behavioral performance, especially in executive function of attention. These results are discussed in context of current views and theories on attentional networks and deficits observed in ADHD patients. National Science Centre Grant 2011/01/D/NZ4/04958.
