A total of 92 patients with hydrocephalus were studied. The incidence of seizures was significantly greater in the "shunted" group (18.2% in the "non-shunted" and 65.4% in the "shunted" group). All of the shunted patients who had seizures developed them after the placement of the shunt. Left sided focal motor seizures were the commonest focal seizures in the patients with right sided shunts. There was a higher incidence of abnormal EEG tracings in the "shunt" group (47% of the "non-shunt" patients and 95% of the "shunt" group). All types of focal EEG abnormalities, but particularly the slow wave foci, were seen more frequently over the hemisphere which had the shunt, and in more than half these localized to the neighborhood of the shunt itself. It is suggested that the shunt, which may act as a foreign body, may be responsible, at least in part, for these findings.
共对92例脑积水患者进行了研究。“分流”组癫痫发作的发生率显著更高（“未分流”组为18.2%，“分流”组为65.4%）。所有发生癫痫的分流患者均在分流装置置入后出现癫痫发作。右侧分流患者中，左侧局灶性运动性癫痫是最常见的局灶性癫痫。“分流”组脑电图异常记录的发生率更高（“未分流”患者为47%，“分流”组为95%）。所有类型的局灶性脑电图异常，尤其是慢波灶，在有分流装置的半球上更频繁出现，且其中一半以上局限于分流装置本身附近。提示分流装置可能作为异物，至少部分导致了这些结果。
