Relationship between IVA Measures and QEEG Pattern in Children with Attention-Deficit/Hyperactivity Disorder

Aim: The aim of this study was to discriminant subtypes of ADHD by means of Quantitative Electroencephalography results. 100 ADHD children aged between 8-12 years old with a diagnosis of ADHD based on Integrated Visual and Auditory Continuous Performance Test (IVA) results were included in this study. We had three types of ADHD based on IVA test including of inattentive type, hyperactive type and combined type.EEG evaluation was performed on these children, using 21 channel EEG device, and their brain waves were recorded from 19 point of their head. Absolute power and relative power of EEG data were calculated for each of patients. We used MANOVA and Discriminate analysis for analysis of data. Findings: The results showed that there is a positive relationship between brain wave patterns in QEEG and different kinds of ADHD diagnosed by IVA test. Relative power (RP) of theta wave could discriminant inattentive type from hyperactive type in ADHD children .there was more theta wave at O2 (Right occipital) in hyperactive type in comparison to inattentive and combined type.
considering that theta in O2 (Right occipital) in hyperactive type is more than inattentive and combined type, Therapist who don’t have access to QEEG evaluation for diagnosis , can be effective in alleviating hyperactive symptoms in hyperactive type by reduction of theta wave in occipital region, particularly in o2.
