Treat encephalitis: Treatment of encephalitis depends upon the cause and clinical progression. Usually, the treatment is supportive, as many cases are viral and there is not a specific cure. However, in hsv encephalitis, Acyclovir is used to treat the virus. In certain cases, hospitalization, nutritional support, fever control, antiseizure medication, mechanical ventilation, and corticosteroids may be needed.
1 An imaging study of the brain such as a CT scan or magnetic resonance imagining (MRI) is often done. MRI is the procedure of choice if herpes encephalitis is suspected.  A study called polymerase chain reaction (PCR) to detect genetic material of the virus has greatly improved the diagnosis of herpes encephalitis. Variations of this test are used by the CDC and some state agencies to identify the various other virus types that may cause encephalitis.
