70 Introduction: Attention-Deficit/Hyperactivity Disorder (ADHD as a neurodevelopmental disorder includes three subtypes predominantly inattentive (ADHD-I), predominantly impulsive/hyperactive (ADHD-H), and predominantly combined (ADHD-C) that has formed a heterogeneity disorder due to differences in pathology and syndrome. This study aimed to evaluate the Electroencephalographic (EEG) characteristics of ADHD subtypes. Methods: Subjects included 61 boys (7-12 years old, normal intelligence)

Children were investigated regarding Child Behavior Checklist and brain electrical activity during eyes-closed resting state (i.e. EEG power in delta (1-4 Hz), Theta (4-8 Hz), Alpha (8-12 Hz) and Beta (12-30Hz) frequency bands. Statistical analysis included a 2x2 factorial design by the additive model. Results : Theta/Beta ratio was higher in all ADHD subtypes, especially the ADHD-I subtypes, compared to normal children. Besides, in the ADHD-I subtype, theta activity was higher and beta activity was lower than Theta. No significant difference found between the groups in delta and alpha activity. Conclusion: According to these results, EEG markers can better distinguish the ADHD-I subtype, which can be explained within the framework of the maturational lag model of the central nervous system. ‫ های کلیدی‬ ‫واژه‬ ‫الکتروانسفالوگرافی‬ ‫فعالی‬ ‫توجه/بیش‬ ‫نقص‬ ‫اختالل‬ ‫افزایشی‬ ‫مدل‬ ‫نویسنده مسئول‬ ‫سازی‬ ‫مدل‬ ‫گروه‬ ‫استادیار‬ ‫خسروآبادی،‬ ‫رضا‬ ‫مغز،‬ ‫و‬ ‫شناختی‬ ‫علوم‬ ‫پژوهشکده‬ ‫شناختی،‬ ‫تهران‬ ‫اوین،‬ ‫میدان‬ ‫بهشتی،‬ ‫شهید‬ ‫دانشگاه‬ R_khosrowabadi@sbu.ac.ir ‫ایمیل:‬ ‫مقدمه‬ ‫فعالی‬ ‫توجه/بیش‬ ‫نقص‬ ‫اختالل‬ ‫اختالالت‬ ‫جزء‬ ‫که‬ ‫است‬ ‫شایع‬ ‫بسیار‬ ‫اختالل‬ ‫یک‬ ‫مالک‬ ‫اساس‬ ‫بر‬ ‫شود.‬ ‫می‬ ‫گرفته‬ ‫نظر‬ ‫در‬ ‫نوجوانان‬ ‫و‬ ‫کودکان‬ ‫پزشکی‬ ‫روان‬ ‫اختالل‬ ‫این‬ ‫شیوع‬ ‫میزان‬ ‫روانی‬ ‫اختالالت‬ ‫آماری‬ ‫و‬ ‫تشخیصی‬ ‫راهنمای‬ ‫همچنین‬ ،)1( ‫باشد‬ ‫می‬ ‫درصد‬ 2/5 ‫بزرگساالن‬ ‫در‬ ‫و‬ ‫درصد‬ 5 ‫کودکان‬ ‫در‬ ‫این‬ .)2( ‫است‬ ‫شده‬ ‫گزارش‬ ‫درصد‬ 10 ‫حدود‬ ‫ایران‬ ‫در‬ ‫آن‬ ‫شیوع‬ ‫میزان‬ ،(Inattention )ADHD-I(( ‫توجه‬ ‫نقص‬ ‫گروه‬ ‫زیر‬ ‫سه‬ ‫دارای‬ ‫اختالل‬ )Hyperactivity-impulsivity )ADHD-H(( ‫فعالی/تکانشگری‬ ‫بیش‬ ‫اشاره‬ ‫مختلفی‬ ‫مطالعات‬ ‫است.‬ )Combined ADHD-C(( ‫ترکیبی‬ ‫نوع‬ ‫و‬ ‫آن‬ ‫های‬ ‫گروه‬ ‫زیر‬ ‫و‬ ‫نیست‬ ‫متجانسی‬ ‫و‬ ‫واحد‬ ‫اختالل‬ ADHD ‫که‬ ‫اند‬ ‫کرده‬ ‫چکیده‬ 71
