What is the treatment for encephalitis?

I am writing a paper on Encephalitis and would like to know what treatment is used for encephalitis

How Is It Diagnosed and Treated?
To diagnose encephalitis, the doctor may take blood samples and order a spinal tap to remove some cerebrospinal fluid (CSF) for testing. CSF is the fluid that surrounds the brain and spinal cord. A spinal tap (also called a lumbar puncture) is a procedure that involves inserting a very thin needle into the lower back to extract a small amount of CSF. The blood and CSF will then be sent to a laboratory to check for viruses or bacteria. A special brain scan (an MRI or a CT scan) may also be ordered to look for inflammation. A doctor may also order an electroencephalogram (EEG). This test records your brain waves and can reveal whether there are abnormalities that are consistent with an encephalitis infection.

Treatment for encephalitis depends on the virus that caused it. People with mild cases of encephalitis can recover at home as long as they're watched carefully by a parent or other adult in the household. Most cases of encephalitis just run their course and the person gets better on his or her own.

Some viruses that cause encephalitis can be treated with medication. For example, acyclovir, an antiviral drug, can help treat encephalitis caused by the herpes simplex virus. In addition, steroid medications may be used to reduce swelling in the brain (these aren't the same as the dangerous performance-enhancing steroids that some athletes use). Because antibiotics are not effective against viruses, they're not used to treat viral encephalitis.

Check out the website of The Encephalitis Society. It's excellent!
