What does encephalitis refer to?

Encephalitis specifically refers to inflammation of the brain tissue, which is most commonly caused by infections. This condition can result from viral, bacterial, or autoimmune processes that lead to swelling in the brain. The inflammatory response can cause a range of neurological symptoms, including headaches, fever, confusion, seizures, and in severe cases, may lead to complications such as brain damage. Understanding this definition is crucial for recognizing the symptoms and potential complications associated with encephalitis, which differs significantly from other medical conditions like cardiomyopathy or conditions affecting the spinal cord.
