Even though the origin and nature of nocturnal paroxysmal dystonia (NPD) remains unclear, it has been considered as a manifestation of the nocturnal frontal lobe epilepsy. We report a 17-year-old man with abnormal stereotyped movement during sleep. Video-EEG monitoring, ictal SPECT and night polysomnography did not show any evidence of epilepsy. However, the partial response to large dose of carbamazepine and the scoring according to the frontal lobe epilepsy and parasomnias (FLEP) scale suggest his events could be classified as epilepsy. Therefore we think the FLEP scale might be a useful tool for differential diagnosis in a patient presenting NPD.

This review describes the wide spectrum of paroxysmal events during sleep in infancy and childhood. The differential diagnosis between sleep-related non-epileptic paroxysmal events and epileptic seizures is difficult in special occasions. The nocturnal frontal lobe seizure and of the more common nonepileptic paroxysmal events during sleep are described. The main differentiating features characterizing parasomnias are: onset in early childhood, rare episodes of long duration, relatively lower frequency per night, absence of stereotypy, gradual disappearance of older age. Video-polysomnography is the gold standard to diagnosing and differentiating parasomnias from nocturnal frontal lobe seizures.

목적： 야간성 전두협 발작 (Nocturnal frontal lobe epilepsy NFLE)은 임상적으로 특징적인 야간성 운동성 발작으로 잘 알려져 있지만 일반적인 MR 영상에서는 대부분에서는 특이한 소견을 보이지 않아 확산 텐서 영상 (DTI)에서의 이상 소견 발현 유무를 알아보고자 한다. 대상 및 방법： 임상적 소견과, EEG 소견으로 진단된 NFLE 환자 6명을 대상으로 DTI 영상을 촬영하였다. 남자 2명, 여자 4명으로 평균연령은 32세 이었다. DTI영상은 single shot spin echo EPI 펄스 열을 사용하였고 사용한 영상 변수는 b value는 0, 1000 s/$\textrm{mm}^2$, TR 10000 msec, TE 71.8/72.3 msec, matrix 128$\times$128 (256 reconstruction), FOV 23cm, 5mm thickness, 2mm interstice gap, NEX 1. 19 slices, time은 4min 21sec (25방향) 이었다. 대조군으로 정상 성인 10명 (평균연령 31세)에서 동일한 방법으로 DTI 영상을 시행하여 분할 비등방도 (fractional anisotropy) 영상을 얻고 전두엽 백질에서 분할 비등방도 값을 측정하여 NFLE 환자군과 비교하였다.
