Encephalitis is mostly caused by viral infections. For instance, Epidemic B encephalitis is caused by the B encephalitis virus, and herpes simplex encephalitis is caused by the herpes simplex virus. Therefore, encephalitis is not related to genetic mutations and is not hereditary, so there is no need for special concern.

It is important to note that some cases of encephalitis are not directly related to viral infections and may be related to autoimmune responses. For example, autoimmune encephalitis can occur in patients experiencing immune system disorder, which may be accompanied by some tumors. A disordered immune system can produce antibodies that attack one's own brain tissue, leading to autoimmune encephalitis. This type of encephalitis also has no genetic tendencies.

How is a brain encephalitis puncture performed?

The encephalitis you mentioned is considered a central nervous system infection. In this case, a definitive diagnosis requires a lumbar puncture, which you referred to as a puncture. The lumbar puncture requires the patient to be in the lateral recumbent position, then the puncture is performed in the interspaces between L1-L3 or L4-L5 on the back to collect cerebrospinal fluid and conduct tests. This also allows for the examination of pathogens and pressure measurements. After the lumbar puncture, the patient needs to lie flat for six hours with a pillow removed to prevent headaches due to low cranial pressure.

Can encephalitis be cured?

The viruses that cause encephalitis are relatively common. Whether they can be cured depends mainly on the type of virus causing the encephalitis, the severity of the condition, and whether the treatment is timely. Generally, most cases of encephalitis, such as those caused by enterovirus infections, tend to self-heal to a certain extent. The focus should be on care to prevent complications, electrolyte disorders, overheating, and to provide appropriate antiviral treatment. Most patients can be cured. However, there are also some more dangerous types of encephalitis, such as encephalitis caused by the type B encephalitis virus, which can rapidly lead to disturbances in consciousness, seizures, and even respiratory involvement, resulting in respiratory failure. This type of encephalitis is more severe and can leave significant sequelae even if successfully treated. For herpes simplex virus encephalitis, as long as the initial symptoms are not particularly severe and antiviral medications are used in a timely manner, the prognosis is still good.

What tests are done for pediatric encephalitis?

Some auxiliary examinations are very necessary for pediatric encephalitis, which help in the diagnosis and differential diagnosis of encephalitis. The main tests generally include the following: First, an electroencephalogram (EEG), which is the most commonly used examination. It is safe, non-invasive, and relatively accurate. Children with encephalitis will show light to moderate abnormalities in the EEG. Combined with the patient's history of fever and headache, it has important clinical significance for the diagnosis of encephalitis. The second important examination is cranial magnetic resonance imaging (MRI). If the encephalitis is severe, pathological changes in the cerebrospinal fluid can be seen on MRI. The third very important examination is lumbar puncture. Lumbar puncture can mainly determine the pressure of the cerebrospinal fluid, the color of the cerebrospinal fluid, and analyze the levels of white blood cells, glucose, and chloride in the cerebrospinal fluid. This is crucial for diagnosing encephalitis and excluding other types of encephalitis.

What to do with pediatric encephalitis

If a child develops encephalitis, it is definitely recommended that they be hospitalized for treatment. It is necessary to assess their condition and determine the cause of the encephalitis: is it viral? Bacterial? Or caused by other pathogens? If encephalitis occurs, aggressive treatment is certainly required. In such cases, if the child is discharged from the hospital, they must regularly revisit the hospital for follow-up examinations, and the development of the child's nervous system must be monitored, focusing on motor and cognitive development. Regular assessments at the hospital are definitely required.

How to prevent encephalitis

Most cases of encephalitis are transmitted through close contact, such as children playing with toys together. It is possible for them to ingest viruses through their hands, which then enter the bloodstream from the stomach and attack the brain. Some cases of encephalitis are also transmitted through the respiratory tract, mainly through droplets. Therefore, in order to prevent encephalitis, it is crucial to maintain hand hygiene, wash hands frequently, and avoid crowded places to prevent respiratory transmission. In addition, to prevent encephalitis, it is important to improve one's physical condition and exercise regularly, as a strong body is less susceptible to viral infections. Finally, it is essential to ensure adequate nutrition for encephalitis prevention, including sufficient daily intake of carbohydrates and dietary fiber, as well as vitamins C and folate, which are crucial for enhancing the body's resistance.
