Clinical Information

A disorder characterized by acute inflammation of the meninges of the brain and/or spinal cord
Brain infection
Inflammation of the coverings of the brain and/or spinal cord, which consist of the pia mater; arachnoid; and dura mater. Infections (viral, bacterial, and fungal) are the most common causes of this condition, but subarachnoid hemorrhage (hemorrhages, subarachnoid), chemical irritation (chemical meningitis), granulomatous conditions, neoplastic conditions (carcinomatous meningitis), and other inflammatory conditions may produce this syndrome. (from Joynt, Clinical Neurology, 1994, ch24, p6)
Inflammation of the meninges
Inflammation of the meninges (three thin layers of tissue that cover and protect the brain and spinal cord). Meningitis is usually caused by a bacterial or viral infection, but sometimes is caused by cancer, drug allergies, or inflammatory diseases
Meningitis is inflammation of the thin tissue that surrounds the brain and spinal cord, called the meninges. There are several types of meningitis. The most common is viral meningitis, which you get when a virus enters the body through the nose or mouth and travels to the brain. Bacterial meningitis is rare, but can be deadly. It usually starts with bacteria that cause a cold-like infection. It can block blood vessels in the brain and lead to stroke and brain damage. It can also harm other organs. pneumococcal infections and meningococcal infections can cause bacterial meningitis.anyone can get meningitis, but it is more common in people whose bodies have trouble fighting infections. Meningitis can progress rapidly. You should seek medical care quickly if you have
- a sudden fever
- a severe headache
- a stiff neck
early treatment can help prevent serious problems, including death. Vaccines can prevent some of the bacterial infections that cause meningitis. Parents of adolescents and students living in college dorms should talk to a doctor about the vaccination
