A 5-year-old child with subacute sclerosing panencephalitis had continuous involuntary ocular movements while awake. At this stage of illness, stereotyped periodic EEG complexes over the two hemispheres were asynchronous. Polygraphic studies showed three diffrent types of ocular movements, each apparently related to the degree of phase shift between the EEG complexes from the two hemispheres. The involuntary ocular movements in one direction were always preceded by periodic EEG complexes from the contralateral hemisphere. Overnight polygraphic studies revealed early disruption of non-rapid eye movement (NREM) sleep patterns and preservation of rapid eye movement (REM) sleep, even in a late stage of illness.
一名患有亚急性硬化性全脑炎的5岁儿童在清醒时出现持续的不自主眼球运动。在疾病的这个阶段，两个半球上刻板的周期性脑电图复合波是不同步的。多导记录研究显示有三种不同类型的眼球运动，每种类型显然都与来自两个半球的脑电图复合波之间的相移程度有关。向一个方向的不自主眼球运动总是先出现对侧半球的周期性脑电图复合波。整夜的多导记录研究显示，即使在疾病晚期，非快速眼动（NREM）睡眠模式也会早期中断，而快速眼动（REM）睡眠则得以保留。
