Meningitis is the
inflammation of the protective membranes covering the
central nervous system, known collectively as the
meninges. Meningitis may develop in response to a number of causes, including infectious agents, physical injury,
cancer, or certain drugs. While some forms of meningitis are mild and resolve on their own, meningitis is a potentially serious condition owing to the proximity of the inflammation to the brain and spinal cord. The potential for serious neurologic damage or even death necessitates prompt medical attention and evaluation. Infectious meningitis, the most common form, is typically treated with
antibiotics and close observation.
