Encephalitis and meningitis facts
- Encephalitis is inflammation of the brain.
- Meningitis is inflammation of the membranes (meninges) that surround the brain and spinal cord.
- Both encephalitis and meningitis can be caused by bacteria or viruses, and rarely a fungus, or be noninfectious.
- Headache and fever are the most common symptoms of encephalitis and meningitis. Stiff neck, confusion, or lethargy can also be present.
- The diagnosis is usually made by performing a lumbar puncture (spinal tap).
- A CT scan or MRI of the brain can also be helpful but usually is only done in addition to the spinal tap.
- Treatment depends on identifying the underlying cause. If bacteria are causing the infection, then antibiotics are indicated.
- Anyone experiencing symptoms of encephalitis or meningitis should see a doctor immediately.
- Depending on the organism causing the infection, close contacts can also become ill and need to be evaluated by a health-care professional.
- Basic methods to prevent the spread of infections (hand washing and covering ones mouth when coughing) can also help prevent the spread of some forms of meningitis.
- Being current on vaccinations will help prevent certain forms of meningitis.
