summary

Encephalitis because of its location is very special, therefore, in clinical practice, the emergence of encephalitis disease is to cause enough attention of patients, and this article next introduces the causes of encephalitis, hoping to cause everyone's attention.

How is encephalitis caused

First of all: encephalitis refers to the inflammatory lesions caused by the invasion of pathogens in the brain parenchyma. Most encephalitis is caused by virus infection. In addition, the presence of parasites and mold can also cause encephalitis. Some may be allergic diseases, such as acute disseminated encephalomyelitis. The so-called encephalitis usually refers to viral encephalitis and post infectious encephalomyelitis which belongs to acute disseminated encephalomyelitis.

Secondly, viral encephalitis virus does not have cell structure, and can be divided into two categories according to the different nucleic acid composition: one is deoxyribonucleic acid virus (DNA virus): including parvovirus, papillomas vacuolating virus (causing progressive multifocal leukoencephalopathy), adenovirus, herpesvirus, varicella zoster virus. The other is RNA virus (RNA virus): including parvovirus (poliovirus, Coxsackie virus, ECHO virus), arbovirus, Myxovirus, (influenza virus), paramyxovirus (measles virus and mumps virus), sand virus (lymphocytic choroid plexus meningitis virus), rhabdovirus (rabies virus). Viral encephalitis can be divided into acute, subacute and chronic encephalitis.

Finally: according to the type of virus and the route of infection, it can be divided into arbovirus, enterovirus, respiratory virus, herpes virus encephalitis and so on. According to the incidence, it can be divided into epidemic encephalitis and sporadic encephalitis. It is generally believed that acute encephalitis represents acute viral infection, while subacute or chronic diseases such as subacute sclerosing panencephalitis and corticostriatal degeneration represent chronic viral infection.

matters needing attention
