Parietal and prerolandic somatosensory evoked potentials (SEPs) to median nerve stimulation were recorded from 40 patients with lacunar syndromes due to CT-verified lacunar infarcts. The control group consisted of 30 age-matched normal controls. Nineteen patients showed SEP abnormalities, mainly an increase of height-covariated latency of cortical components and/or of the central conduction time. Such changes occurred independently of the clinical features of lacunar syndromes, being related more to the lesion location than to its size. SEP studies may be a useful adjunct to the clinical diagnosis of lacunar infarct, possibly also when the CT scans are normal.
对40例经CT证实为腔隙性梗死所致腔隙综合征患者，记录了刺激正中神经时的顶叶和中央前回体感诱发电位（SEP）。对照组由30名年龄匹配的正常对照者组成。19例患者出现SEP异常，主要表现为皮质成分的高度协方差潜伏期和/或中枢传导时间增加。这些变化与腔隙综合征的临床特征无关，更多地与病变部位而非大小有关。SEP研究可能是腔隙性梗死临床诊断的有用辅助手段，甚至在CT扫描正常时也可能如此。
