Why is Encephalitis so Dangerous?

In answer to this important question, we have to say quite simply: the brain. Encephalitis leads to brain swelling. Any illness of the brain is serious but swelling can lead to a number of other problems, many of them life threatening. The brain is the control center for the entire body, sending and receiving information from crucial organs such as the heart, lungs and stomach.

The basic causes vary, depending on virus and bacteria that might be at the root of the problem. This makes encephalitis difficult for doctors to treat. When a person experiences confusion, difficulty thinking/loss of memory, along with trouble in other areas of the body, the cause could be the swelling of the brain from encephalitis. Of course, there are many other reasons for memory loss and similar symptoms, but a doctor can generally determine right away if brain swelling is the cause. If the swelling is not dealt with immediately and correctly, the brain can be damaged permanently.

Some people suffered from brain swelling associated with encephalitis after contracting West Nile virus from a mosquito bite. Others may have this condition because of meningitis. The first signs of encephalitis may be dismissed as a less serious condition since a slight fever or change in behavior can be attributed to other causes. But this makes the malady that much more dangerous. People may ignore the early-warning signs and ultimately have permanent damage to the brain that slows speech or makes clear thinking much more difficult.
In a few cases, swelling of the brain can be life-threatening. The brain is complex and crucial to a healthy life, but it is also quite sensitive. Swelling may cause some of the life-sustaining systems of the body to stop working altogether. If the lungs and heart don’t work properly there is a good chance of permanent damage or death. Unfortunately, there is a vicious circle connected with encephalitis. Swelling in the brain may lead to seizure, which can then lead to additional swelling and so on.

It seems that encephalitis is more hazardous to young children and to older adults who may have less strength and resiliency to overcome the effects of this condition. A healthy adult may be able to return to perfect health after encephalitis caused by bacteria or virus infection. A specific program of antibiotics (for bacteria) combined with some medication for seizure or virus can reverse the condition. Severe swelling may require surgery to relieve pressure on the brain.
People who develop brain swelling from encephalitis usually find that the most difficult symptoms are less intense after several days. But most people also find that it takes many weeks, even a month or two, to begin to see true recovery. Maintaining a strong immune system through proper diet and healthy lifestyle can help prevent encephalitis. While there is no way to protect yourself against this serious condition 100 percent of the time, it is possible to reduce the chance of being infected from an insect bite or from an unhealthy environment.
