10 Obnoxious Effects Of Mumps

3. Meningoencephalitis

Meningoencephalitis, as the name suggests, is an infection affecting both the brain (encephalitis) and meninges (meningitis). Both present signs of inflammation and the main symptom of meningoencephalitis is swelling of the brain tissue and meninges, which is a protective barrier of the brain and spinal cord. It is usually caused by a viral infection, and a fairly common cause of mumps, but only in rare cases is it serious enough to cause death or neurological complications.
