本文分析了22例小儿瘫痪型散发性脑炎的脑电图的早期表现、远期变化及其与临床症状的联系。发病25天内检查脑电图者均异常,在弥漫性异常的背景中出现与临床瘫痪症状相符的局灶性改变是本组早期脑电波表现的基本特点。4年后仍有63.2%的患儿脑电图异常,值得注意的是脑电图与临床间原有的平行关系在此期已不明显,甚至相矛盾。并且在5例α波不对称者中,4例为瘫肢同侧α指数减少,这与原早期同侧异常程度较轻及目前所遗留的神经病学体征明显不一致。 This article analyzes the early manifestation and long-term changes of EEG in 22 cases of pediatric paralytic sporadic encephalitis and their relationship with clinical symptoms. EEG examination within 25 days of onset were abnormal in the background of diffuse abnormalities and symptoms of clinical paralysis consistent with the focal changes in this group is the basic characteristics of early brain wave performance. After 4 years, 63.2% of the patients still had EEG abnormalities. It is noteworthy that the original parallel relationship between EEG and clinic has not been obvious or even contradictory in this period. And in 5 cases of α-wave asymmetry, 4 cases of paralyzed limb ipsilateral α index decreased, which is consistent with the lesser extent of the original early ipsilateral anomalies and the current neurological signs left behind.
