Common Causes of Encephalitis
Infections in the brain and spinal cord can cause dangerous inflammation. This inflammation can produce a wide range of symptoms, and in extreme cases, can cause brain damage, stroke, seizures, or even death. Encephalitis is an inflammation of the brain itself. Encephalitis can be caused by bacterial infection and, most often, viral infections.
Primary encephalitis (also called acute viral encephalitis) is caused by a direct viral infection of the spinal cord and brain.
Secondary encephalitis, also known as post-infective encephalitis, a viral infection first occurs elsewhere in your body and then travels to your brain.
