病毒学和免疫学技术的进展,证实许多中枢神经系统的感染是病毒所致。近年来还发现某些脱髓鞘性和变性疾病也与病毒(慢病毒)感染有关。由于病毒可侵犯中枢神经系统的不同结构和部位(如脑膜、脑脊髓灰白质等),而有各种的病理临床特征,加上目前对某些病毒的分离和鉴别仍有困难,增加临床诊断分类的复杂性。近年来散发的脑炎病例有增多趋势,在目前条件下又未能作出病源学诊断,临床上有不少问题须进一步观察和探讨。这里概述病毒性脑炎诊断和治疗的一些问题,供参考。
Advances in virology and immunology have confirmed that many CNS infections are caused by viruses. In recent years, it has also been found that certain demyelinating and degenerative diseases are also associated with virus (lentivirus) infection. As the virus can invade the different structures and parts of the central nervous system (such as the meninges, brain and spinal cord gray matter, etc.), and a variety of pathological clinical features, coupled with the current separation and identification of certain viruses is still difficult to increase clinical diagnosis The complexity of classification. In recent years, the distribution of encephalitis cases have an increasing trend in the current conditions failed to make etiological diagnosis, there are many clinical issues to be further observed and discussed. Here are some of the problems in the diagnosis and treatment of viral encephalitis for reference.
