Causes Of Meningitis- Meningitis-Bacterial Meningitis-Viral Meningitis

Meningitis affects the brain and the spinal column; hence it can be one of the most dangerous infections of all. One of the most important ways to learn how to deal with this condition is to learn what are the causes of meningitis.

Meningitis can be a very frightening condition to contract. It specifically refers to infections that occur in the membranes that surround both the spinal column and the brain. As these are both important parts of the human body, it goes without saying that these infections can be highly dangerous. They are usually caused by bacteria and viruses.

One of the main reasons why meningitis is often misdiagnosed is because the symptoms are similar to those of flu. The symptoms can be as commonplace as headache, fever and mild disorientation. In more serious cases however, meningitis can lead to seizures, brain damage, strokes and even death.

Under normal conditions, your body's immune system will be able to handle the onslaught of any virus or bacteria. In the case of meningitis however, the infection quickly passes into the blood stream before it can be contained. From there, it is easily transported into the cerebrospinal fluid and then into the membranes covering the brain and spinal cord. The infection causes the membranes to swell and in severe cases, this can cause the nerve cells to rupture or even bleed in the brain.

There are different strains of meningitis but the most dangerous is one that is called Bacterial Meningitis. This causes an infection in the upper respiratory tract before traveling on to the brain. This form of meningitis can cause strokes, brain damage and in some cases, death.

The most common form of meningitis is known as Viral Meningitis. Thankfully, this is a very mild and non-lethal strain but it can easily be transmitted from one person to another.
