Abstract:
OBJECTIVES: This study was designed to investigate the clinical availability of quantitative electroencephalography (QEEG) as an auxiliary diagnostic tool in attention-deficit hyperactivity disorder (ADHD). METHODS: A total 95 participants completed examinations, which included Korean ADHD Rating Scale (K-ARS), Diagnostic Interview Schedule for Children Version IV-Korean Version (DISC-IV), and QEEG. From the result of the DISC-IV, we divided them into three groups, ADHD, ADHD NOS (not otherwise specified), and Normal control. The QEEG was analyzed by the ranges of Hz : delta (1-4 Hz), theta (4-8 Hz), alpha (8-12 Hz), beta (12-25 Hz), and high beta (25-30 Hz). RESULTS: ADHD NOS group showed significantly decreased delta activity (NOSnormal, p=0.044) compared with normal control. ADHD group showed increased high beta activity (ADHD>NOS, p=0.043) compared with NOS group. The z-scores of relative power of theta were negatively correlated with the K-ARS at O1, O2 electrodes of ADHD group. On the other hand, the z-scores of relative power of high beta were negatively correlated with the K-ARS at F7, F8 electrodes of ADHD NOS group. CONCLUSION: We confirmed QEEG abnormalities in ADHD patients, especially the difference between ADHD NOS and Normal control. Therefore, we expect to use QEEG as the valuable tool to diagnose ADHD accurately.
