Comparison of Quantitative Electroencephalography in Adults with Attention Deficit/Hyperactivity Disorder Versus non-Afflicted Individuals

Abstract

Attention Deficit Hyperactivity Disorder is one of the psychologic common disorders that is sometimes not properly diagnosed due to lack of attention. In this study, attention was paid to the evaluation of brain stimulation in order to diagnose this condition. Methods: People who have been diagnosed with Adult ADHD were selected from among those referred to the psychiatric clinic. The control group was also selected from non-psychiatric outpatient clinics and patients hospitalized in the internal department. Then above groups were examined and compared with QEEG and the above data were analyzed and examined. Results: At rest: 1. The mean absolute power scores of Beta_Posterior and Beta1_Posterior waves were lower in the ADHD group. 2. ADHD group had lower mean relative power scores of Delta_Anterior and Delta_Central waves compared to the control group. But in the High Beta Anterior, Gamma Anterior, High Gamma Anterior, High Gamma Central, High Gamma Posterior, Beta2 Anterior, Gamma1 Anterior, Gamma2 Anterior, Gamma2 Central waves, they had higher mean relative power scores. During Time/Movment anticipation: 1. Gamma2 Anterior mean score was higher in ADHD group. 2. In ADHD group mean relative power scores in Delta_Anterior and Delta_Central waves were lower than control group. But those scores were higher in Gamma Anterior, High Gamma Anterior, High Gamma Central and Gamma2 Anterior waves. 3. Mean peak frequency score in High Beta Central and High Beta Posterior waves was lower in ADHD group. But that score was higher in Gamma Anterior, Gamma Central, Gamma Posterior, Gamma1 Posterior and Gamma2 Anterior waves.
