It is known that attention deficit/hyperactivity disorder is a widely spread condition in school aged childhood population. Making of precise diagnosis is a serious problem of modern pediatric neurology. In spite of large amount of guidelines and questionnaires the unified consensus of diagnosis is still absent. Thus it is important to search additional diagnostic criteria which can help physicians to confirm ADHD. For this purposes we have used quantative EEG (QEEG) parameters. There are numerous papers regarding QEEG changes of ADHD children during baseline (resting with closed eyes, resting with opened eyes, photic stimulation, hyperventilation).But information concerning QEEG evidences during cognitive tasks is insufficient. For this purposes we have used QEEG during Raven test, reading and calculation in children with ADHD and control group. QEEG was carried out according to standard 10-20 electrode placement rule from the following derivations: F3, F4, C3, C4, P3, P4, O1, O2. We have observed that in controls fulfilling of Raven test is more difficult than reading. Thus they are eulectic but in ADHD children reading is more difficult than Raven test. Thus they are dyslexic. By means of alpha and delta bands analysis it became apparent that alpha band is inversely proportional to mental effort and delta band is directly proportional to mental activity.
