Attention deficit hyperactivity disorder (ADHD) is a common behavioral diagnosis based on the presence of developmentally inappropriate levels of inattentiveness, overactivity and impulsivity. The prevalence for ADHD among children is estimated at about 3–10%, affecting boys 5 times more often than girls. The aim of the study was to investigate the patterns of attentional functions and brain activity measured with electroencephalography (EEG) in a clinical group aged 11–16 compared with healthy, age- and sexmatched controls. We focused on efficiency of alerting, orienting and executive networks assessed using Posner’s Attention Network Test (ANT) paradigm. Further, the EEG recordings were collected while the participants performed the ANT test. The obtained results, including reaction time (RT) values, Event Related Potential (P300) and time-frequency analyses, are discussed within the context of existing theories of ADHD-related deficits. The project was supported by The National Science Centre, grant number: 2011/01/D/NZ4/04958.
