病毒性脑炎125例的临床与脑电图分析

Electroencephalogram examination and clinical analysis of virus encephalitis in 125 cases

目的:探讨病毒性脑炎的临床特点及脑电图对病毒性脑炎的诊断价值。方法:对125例病毒性脑炎患者的临床表现和脑电图、脑脊液及影像学检查等作比较分析。结果:病毒性脑炎的发病以儿童和青壮年为主(88.0%),常急性或亚急性起病(98.4%);首发症状多,临床表现多种多样。脑电图异常率86.4%,脑脊液异常率60.8%,CT检查异常率28.1%,MRI检查异常率50.7%。结论:脑电图检查较CT和MRI检查更敏感,优于脑脊液检查,脑电图对病毒性脑炎早诊断有重要意义。

Objectlve ：To study the clinical characteristic of virus encephalitis and the diagnosing value of electroencephalogram to virus encephalitis.Methods：Three diagnosing methods including electroencephalogram, cerebrospinal fluid and imaging examination were compared in 125 cases with viral encephalitis.Results ：Virus encephalitis was commonly in children and the middle age people （88.0%）.h was frequently acute or subacute （98.4%）.The initial symptom and clinical manifestation in virus encephalitis were various.Tile abnomal rate in electroencephalograph was 86.4%, and 60.8% in cerebrospinal fluid examination, and 28.1% in brain X-ray computed tomography （CT） and 50.7% in magnetic resonance imaging （MRI） examination respectively.Conclusion：Electroencephalogram examination is better than other three methods such as cerebrospinal fluid,brain CT and MRI examination.Therefore,there is an important meaning for early diagnosing virus encephalitis by electroencephalogram.
