Frequently Asked Questions
Meningitis
1. What is Meningitis?
Meningitis is an inflammation and swelling of the membranes that cover the brain and spinal cord. These membranes are called meninges. Meningitis is most often caused by an infection. This disease can be fatal or cause serious lasting side effects.
2. What are the causes of Meningitis?
The two main causes of Meningitis are viruses and bacteria. Common bacteria or viruses may cause infection in a part of the body -- the skin, gastrointestinal tract, or respiratory tract, for instance. They then may spread through the bloodstream to the nervous system. Bacteria can also enter the nervous system directly after severe head trauma or head surgery, or following an infection in the head.
Fungi, protozoa, and other parasites are less common causes of Meningitis. In very rare cases, cancer, other diseases, or certain medications may also lead to inflammation of the meninges.
3. What is bacterial Meningitis?
Bacterial Meningitis is serious, occurring more often in winter months. A common cause affecting teens is the bacterium Neisseria meningitidis, which causes meningococcal disease. It can be fatal if you don't receive treatment right away. The bacteria that cause it live in the noses and throats of up to a quarter of the population. It is not known why these bacteria sometimes travel to the nervous system and cause Meningitis. Another leading cause of bacterial Meningitis is Streptococcus pneumoniae.
4. What is viral Meningitis?
Viral Meningitis is more common and usually less serious. It tends to occur more often in the summer and fall. Because of its flu-like symptoms, many people mistake it for the flu. Viruses that cause "stomach flu" are a cause of viral Meningitis, but most people who have these infections don't develop Meningitis. Others viruses that lead to Meningitis are those that cause chickenpox, mononucleosis (mono), and herpes. Symptoms can be similar to those of bacterial Meningitis.
5. What is fungal Meningitis?
Fungal Meningitis is rare, but people can get it by inhaling fungal spores from the environment. People with certain medical conditions, like diabetes, cancer, or HIV, are at higher risk of fungal meningitis.
6. What is parasitic Meningitis?
Various parasites can cause meningitis or can affect the brain or nervous system in other ways. Overall, parasitic meningitis is much less common than viral and bacterial meningitis.
6. What is amebic Meningitis?
Primary amebic meningoencephalitis (PAM) is a rare and devastating infection of the brain caused by Naegleria fowleri. Naegleria fowleri is a free-living microscopic ameba that lives in warm water and soil.
7. Who is at risk for Meningitis?
A person of any age may develop bacterial Meningitis. But it is more common in infants and young children and in people older than age 60. Because of close contact with peers, teens and college students are at greater risk, too. Although more common in children, viral Meningitis occurs in people of all ages. Having a weakened immune system or traveling to certain foreign countries also increases your risk for Meningitis.
8. Is Meningitis contagious?
Close contact - not casual contact at work or school - can spread the bacteria and viruses that cause Meningitis. This includes kissing, coughing, or sneezing. Sharing eating utensils, glasses, food, or towels can also spread these bacteria and viruses.
9. What are the signs and symptoms of Meningitis?
Although symptoms may vary, the more common signs and symptoms of Meningitis include:
- High fever
- Severe, persistent headaches
- Neck stiffness
- Vomiting
- Discomfort in bright lights
- Drowsiness
- Lack of appetite
- Later symptoms can include rash, seizure, and coma. Infants with Meningitis may be lethargic, irritable, or not feed well.
10. Is Meningitis contagious?
Call the doctor and describe the signs and symptoms. If you cannot reach a doctor, go to the nearest Hospital right away.
11. How do doctors diagnose Meningitis?
In addition to taking a history and doing a physical exam, the doctor will collect a sample of spinal fluid, called a spinal tap. The doctor inserts a needle into the lower back to remove the fluid. The doctor examines this sample for signs of inflammation and infection. Other tests may include:
- A neurological exam to test nerve, motor, and sensory function; hearing, speech, and vision, balance and mental status.
- Blood and urine tests
- Throat culture
- Computed tomography (CT), magnetic resonance imaging (MRI), or electroencephalography (EEG) to spot abnormalities in the brain.
11. How do doctors treat Meningitis?
Depending upon the severity of illness, you may need to be hospitalized. Bacterial
infections require prompt treatment with intravenous antibiotics. This may begin even
before diagnosis is confirmed. Treatment for viral infections is mainly aimed at
relieving symptoms. As needed, treatment may also include:
- Intravenous fluids
- Anticonvulsants for any seizures
- Pain relievers
- Other treatments for brain swelling
12. What are the long-term effects of Meningitis?
The outcome of Meningitis depends on the cause of the infection, how quickly treatment
begins, and how ill the person becomes. However, these are possible long-term side
effects of the disease:
- Fatigue
- Recurring headaches
- Memory or concentration problems
- Mood swings or aggression
- Balance problems or clumsiness
- Temporary or permanent deafness
- Loss of vision, seizures, or brain damage (rare)
- Loss of limbs
13. Is it possible to prevent Meningitis?x
There are four vaccines are available to prevent bacterial Meningitis. If not previously
vaccinated, teens entering high school or entering college (and who will be living in a
hostel / dormitory) should be vaccinated. The doctor may suggest other steps to prevent
Meningitis:
- Antibiotics, if you've come into close contact with someone who has had some kinds of bacterial Meningitis.
- Other vaccines.
- Good hygiene, such as regular hand washing.
- Not sharing food, drinks, or utensils.
