Meningitis is inflammation of the thin tissue that surrounds the brain and spinal cord, called the meninges. There are several types of meningitis which include: bacterial, parasitic, fungal, viral, amebic, and non-infectious. The most common is viral meningitis. Viral meningitis may cause headaches, fever, stiff neck, seizures, sensitivity to bright light, sleepiness, lethargy, nausea and vomiting, and/or a decreased appetite. Each type of meningitis has a slightly different cause, but each ultimately acts in the same way: a virus spreads through the bloodstream until it reaches the brain, or spinal cord where it sets up in the lining or fluids around these vital body parts and starts developing into a more advanced infection. Viral meningitis may resolve on its own, but some causes of viral meningitis will be treated with intravenous antiviral medications.
