Causes Of Encephalitis

The exact cause of brain infection remains unclear. But, the viral infection is the most common cause associated with the disease. It can also occur due to bacterial infection as well as noninfectious inflammatory conditions.

Types Of Encephalitis

Depending on the cause of the brain inflammation, you can classify the problem into two types. The two major types are:

Primary Encephalitis

It is the condition affecting your brain when a virus or other agents directly cause infection. The infection can affect one area specifically or can spread to other areas. The primary infection can occur due to the reactivation of the virus that has remained dormant after a previous illness.

Secondary Encephalitis

It is the brain inflammation that results from a problematic immune system reaction to any of the infection occurring in any parts of your body. Instead of attacking the abnormal cells, triggering infection, the immune system attacks your healthy brain cells. The problem is also known as post-infection encephalitis. It occurs mainly after two to three weeks after suffering from the initial infection.

Common Viral Causes Triggering Encephalitis

Certain viruses can trigger brain inflammation. The common viral issues triggering encephalitis include the following:

Herpes Simplex Virus (HSV)

HSV type 1 and 2 virus can cause encephalitis. The HSV type 1 can trigger fever blisters and cold sores around your mouth while HSV type 2 leads to genital herpes. HSV type 1 triggered brain inflammation occurs rarely. But, it can result in significant brain damage or ultimately death.

Other Herpes Virus

You can also suffer from brain inflammation due to other herpes viruses, such as Epstein-Barr virus. It mostly causes infectious mononucleosis. The varicella-zoster virus causing shingles and chicken pox can also affect your brain.


The viruses, including coxsackievirus and poliovirus, which causes symptoms like eye inflammation, abdominal pain or flu-like signs can also cause encephalitis.

Mosquito-Borne Viruses

Mosquito-Borne Viruses
West Nile virus transmission cycle

The mosquito-borne virus can trigger symptoms with a few days to a couple of weeks after you receive the bite. The viruses can cause infections like:

  • Louis
  • West Nile
  • Western and Eastern Equine Encephalitis
  • La Crosse

Tick-Borne Viruses

Tick-Borne Viruses

You can suffer from encephalitis due to getting a bite from the Powassan virus-infected ticks. It is the common cause of brain inflammation in the Midwestern United States. You can observe the signs one week after getting a bite from the infected tick.

Brain Imaging

The sophisticated brain imaging techniques like MRI or CT scans can reveal the presence of brain swelling or other conditions. It can also reveal issues like tumors that can trigger such symptoms.

Spinal Tap/ Lumbar Puncture

Spinal Tap/ Lumbar Puncture

It is the test that detects any problem with your brain by analyzing CSF (Cerebro-spinal fluid). CSF is the protective fluid surrounding your brain as well as the spinal column. The CSF is removed using a needle from your lower back. The fluid is tested to detect changes in the fluid. So, it can detect infection and inflammation. The sample of CSF can also detect the virus and other infectious agents.

Other Lab Tests

Your doctor takes the sample of urine, blood or excretion from the back of your throat to detect the presence of the virus as well as infectious agents.

Electroencephalogram (EEG)

EEG can detect the brain’s electrical activity. The doctor fixes electrodes on your scalp. The diagnostic test can identify the abnormal pattern of the brain due to encephalitis.

Brain Biopsy

When the treatment options fail to provide you relief, your doctor can suggest brain biopsy. During the test, a small sample of tissue gets tested. It is removed by your doctor and sent to the lab to find the exact problem.

Treatment For Encephalitis

The treatment for brain inflammation depends on the severity of the problem. It also depends on your age as well as the form and cause of the condition. The treatment options available are:
