Encephalitis is the inflammation of the brain by blood-borne immune cells. It is not to be confused with neuroinflammation, which is the modern inflammation of the nervous system by tissue-resident immune cells. Unlike with neuroinflammation, encephalitis is associated with swelling of the brain and can be detected using magnetic resonance imaging (MRI).
