초록

목 적: 주의력 결핍/과잉 운동 장애(ADHD)를 진단받은 환아를 대상으로 뇌파 결과의 차이 및 이에 따른 역학적 비교를 하고자 하였으며 뇌파의 차이에 따른 경련 발현의 차이를 비교해보고자 하였다. 또한 ADHD의 치료제로 사용되는 중추신경자극제의 사용과 경련 발현과의 연관성을 비교하고자 하였다. 방 법: 2001년 1월부터 2005년 12월까지 주의산만을 주소로 충북대학교병원 소아청소년과 및 소아정신과 외래를 내원한 환아를 대상으로 의무기록지 고찰을 통해 후향적으로 분석하였다. 결과: 이전 경련의 병력이 없는 환아중 주의산만을 주소로 본원 신경정신과를 방문한 환아를 대상으로 하였다. 대상 연령은 4세에서 17세 사이로 총 308명의 환아들 중 84명의 환아에서 뇌파를 시행하였으며 그중 남자가 72명(85.7%, 평균 연령 9.3세), 여자가 12명(14.3%, 평균 연령 8.0세)이었다. 정상뇌파소견을 보인 환아가 65명(77.4%), 이상뇌파소견을 보인 환아가 19명(22.6%)였으며 이중 경련증상을 보인 환아는 각각 1명(0.15%), 3명(15.7%)이었다. 중추신경자극제를 처방 받은 환자는 59명, 그렇지 않은 환자는 25명이었고 그중 경련증상을 보인경우는 각각 2명(3.4%), 2명(8.0%)로 나타났다. 결 론: ADHD 환아들은 임상에서는 표출되지 않으나 뇌파에서의 잠재적인 이상 소견 보일 수 있다. 본 연구에서는 이러한 뇌파의 이상 소견과 추후 경련 발현 여부와는 매우 높은 연관성을 보이고 있으며, ADHD의 치료로써 사용된 methylphenidate의 사용에 따른 경련 발현과의 통계적 유의성은 보이지 않았다. 따라서 ADHD 환아들에서 뇌파의 이상 소견이 보일 경우는 향후 경련 발현에 대한 보다 주의 깊은 추적 관찰과 함께 ADHD 환아들의 삶의 질 향상에 대한 적극적인 치료가 필요할 것으로 사료된다.

Purpose : Attention deficit hyperactivity disorder (ADHD) is a syndrome characterized by inattention, impulsive disruptive behavior, impaired concentration, and motor restlessness. This study examined the relationships among electroencephalographic (EEG) findings, stimulant use, and seizure occurrence in children with ADHD. Methods : We retrospectively studied 308 children with ADHD who visited the neuropsychiatric clinic of our hospital from January 2001 to December 2005. We retrospectively analyzed age distribution, etiology, abnormal EEG findings, and use of CNS stimulants. Among these children, brain waves was recorded in 84 patients. Results : Eighty-four children (72 males, 85.7%, 9.3 years mean age; 12 females, 14.3%, 8.0 years mean age) with ADHD had electroencephalograms (EEGs) performed at our institute. Nineteen patients (22.6%) demonstrated epileptiform abnormalities, and 65 (77.4%) demonstrated normal EEGs. Stimulant therapy was applied to 59 of 84 patients (70.2%). Seizures occurred in 1 of 65 patients with a normal EEG (incidence, 1.5%) and 3 of 19 treated patients with epileptiform EEGs (incidence, 15.7%). Conclusion : These data suggest that patients with normal EEGs have minor risk for seizure. In contrast, patients with epileptiform EEGs have higher risk for seizure than patients with normal EEGs.
