Meningitis overview


 * Associate Editor(s)-In-Chief:

Overview
Meningitis is the inflammation of the protective membranes covering the central nervous system, known collectively as the meninges (the leptomeninges and underlying subarachnoid cerebrospinal fluid). Meningitis may develop in response to a number of causes, including infectious agents (bacteria, viruses, fungi, or other organisms), 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.
