본 연구는 삼성의료원 소아정신과 학습장애 특수 클리닉에 내원한 학습부진 아동을 대상으로 학습부진의 원인이 되는 장애와 학습부진 아동에서 학습장애의 유병율을 알아보고자 하였다 이들은 $6{\sim}15$세 사이의 197명으로 구성되었으며 결과는 아래와 같았다. 1) 대상군중 우울증등의 정서장애가 33%로 가장 많았으며 주의력결핍 과잉황동장애가 31%로 두번째의 빈도를 나타내었다. 2) 대상군중 학습장애 환아는 41명으로 20.8%의 빈도율을 보였다. 3) 학습장애의 공존병리중 주의력결핍 과잉활동장애가 44%로 가장 높은 빈도를 나타내었다. 4) 주의력결핍 과잉활동장애가 공존하는 학습장애군과 학습장애만 있는 군에서는 성별이나 연령차이, 지능차이는 없었으며 뇌파의 이상 소견에 대해서도 차이가 없었다. 그러나 주의력결핍 과잉활동장애가 없는 단독 학습장애군은 주의력결핍 과잉활동장애가 공존하는 학습장애군보다 더 늦은 나이에 발병하였고 학업성취도 면에서 우수하였는데 특히 국어, 수학, 사회, 음악 과목에서 격차가 컸다.
