Aseptic meningitis is a disease caused by the inflammation of the protective membranes covering the brain and spinal cord known as the meninges. Unlike other forms of meningitis, aseptic meningitis is not caused by infection and cannot be spread person-to-person. Instead it can be caused by lupus, cancers, certain drugs, head injury, and brain surgery, among others. Meningitis is characterized by a sudden onset of fever, headache, and stiff neck. It is often accompanied by other symptoms, such as nausea, vomiting, photophobia (sensitivity to light), and altered mental status (confusion).
