- Sudden fever
- Heightened sensitivity to light

In extreme cases of encephalitis, complications can include:
Encephalitis treatment may involve antiviral medications being prescribed for herpes encephalitis or other severe viral infections. Anticonvulsants are used to prevent or treat seizures. Corticosteroids are used to reduce brain swelling and inflammation. Sedatives may be needed for irritability or restlessness. Over-the-counter medications may be used for fever and headache. Individuals with encephalitis or bacterial meningitis are usually hospitalized for treatment.
