자폐 스펙트럼 장애(Autism Spectrum Disorder, ASD)는 지적장애와 높은 비율의 동반이환을 보인다고 알려져 있음에도, 기존의 EEG 연구는 이러한 동반이환에 대한 고려 없이 단순히 ASD 집단과 정상 발달 집단을 비교하였다. 본 연구의 목적은 지적장애를 동반한 ASD 집단과 지적장애 집단의 EEG 파워를 비교하는 것이다. 이러한 목적을 위해 2채널 EEG 디바이스를 이용해 휴식 조건과 특정 과제 조건에서 각 집단의 EEG 파워를 비교하였다. EEG 파워의 경우 각 주파수에서의 절대 파워와 상대 파워를 계산하였다. 연구 결과, 휴식 조건의 경우 모든 주파수의 절대 및 상대 파워에서 집단 간 유의한 차이가 나타나지 않았고, 과제 조건의 경우 감마 주파수의 절대 파워를 제외한 모든 절대 및 상대 파워에서 집단 간 유의한 차이가 나타나지 않았다. 이러한 결과는 ASD와 지적장애 집단의 EEG 패턴이 유사성을 가지며, 추후 ASD 집단을 대상으로한 EEG 연구 시 지적장애 여부에 대한 고려가 필수적임을 시사한다.


Persons with autism spectrum disorder(ASD) show high rates of comorbidity with intellectual disability(ID). However, previous EEG studies simply compared ASD group to typical developing group without considering comorbidity. The purpose of this study was to compare EEG power of persons with ID to that of persons with ASD comorbid with ID. For this purpose, EEG was measured using a portable 2 channel device, Braino, at rest and during a specific task. Absolute and relative power of various frequency bands were calculated. The results showed that there were no group differences in all frequency bands at rest and in all frequency bands except absolute gamma power during a task. In terms of absolute gamma power, persons with ASD comorbid with ID showed a significantly higher power than that of persons with ID. Theses results suggested that there were similarities in EEG power of ASD and ID, therefore it is necessary to control for ID when conducting EEG power in persons with ASD.
