Inflammation of the brain, typically resulting from a viral infection. This condition occurs in two forms:
- Primary encephalitis – direct viral infection of the brain and spinal cord.
- Secondary encephalitis – indirect viral infection that first occurs elsewhere in the body but eventually travels to the brain.
Most cases of encephalitis are caused by a viral infection, but they can also be caused by other certain diseases that result in an inflammation of the brain.
Symptoms of encephalitis include a sudden onset of fever, headache, nausea, visual complications, stiff neck and back, drowsiness, seizures and muscle weakness.
Treatment procedures can include taking anti-inflammatory drugs, antibiotics, medications to control brain swelling and pressure and fluid replacement techniques.
