Encephalitis May 2011

What does this mean?

Encephalitis is inflammation of the brain. It can occur at any age. The inflammation is caused either by an infection invading the brain (infectious); or through the immune system attacking the brain in error (post-infectious / auto-immune encephalitis). The inflammation can damage nerve cells resulting in “acquired brain injury”. Encephalitis frequently begins with a flu-like illness or headache. Typically more serious symptoms follow hours to days later.
