Possibly. Encephalitis is an inflammation of the brain usually due to infection. Curing encephalitis depends on the cause and how severe it is. People frequently recover from viral encephalitis but if the infection is severe it can leave permanent brain damage. See this web page for a list of some causes and treatments of encephalitis: http://www. Ncbi. Nlm. Nih. Gov/pubmedhealth/pmh0002388/.
May depend on cause. Hard question to answer briefly as encephalitis is a general term referring to very serious infxn of the central nervous system by any of a broad range of viruses, or rarely parasites. The prognosis & treatment vary depending on specific diagnosis, but one can recover from encephalitis (sometimes with lingering defects). Supportive care is always important, & some forms have specific treatments.
