Encephalitis in children is generally treated based on the cause of the infection. It could be caused by viral infections, bacterial infections, or other pathogens. The most basic treatment is definitely to address the cause of the encephalitis. If there are other symptoms such as fever or seizures, symptomatic treatment should be administered based on these symptoms. The treatment plan should be tailored to the specific condition of the child.

How is encephalitis transmitted?

The commonly mentioned encephalitis is mainly caused by viral infections. There are many types of viruses that can cause encephalitis, including the more severe herpes simplex virus, varicella-zoster virus, etc. There are also some enteroviruses, like Coxsackie virus, and some adenoviruses. Typically, the transmission of encephalitis can occur via the fecal-oral route, where some enteroviruses enter the digestive tract through this route, then from the cells of the digestive tract to the bloodstream, and from there to the brain. Additionally, some viruses are transmitted through blood contact. For instance, if a patient has blisters that rupture and release a large amount of virus, and another person's blood comes into contact with these fluids, transmission can occur via blood. Generally, encephalitis is primarily transmitted through fecal-oral routes and bloodborne transmission.

Symptoms of baby encephalitis

Generally speaking, the symptoms of encephalitis in babies usually start with fever. Encephalitis is an infectious disease, and the majority of cases present with fever, which could be either high or low. Next is vomiting. Since small infants cannot express headache, they usually manifest symptoms through crying, irritability, and restlessness. Additionally, there might be lethargy and malaise. Some may experience seizures, and others might have stiff neck, characterized by rigidity of the neck and changes in muscle tone of the limbs, among other symptoms. These are all symptoms of encephalitis.

Does encephalitis cause a runny nose?

Encephalitis can potentially cause a runny nose, as it is mainly caused by viral infections. These infections not only invade brain cells, leading to symptoms such as fever, headache, nausea, vomiting, and even seizures related to the nervous system, but can also affect the respiratory tract. If these viruses accumulate in the respiratory tract, particularly in the nasal mucosa, they will definitely cause symptoms such as a runny nose, cough, expectoration, and sore throat. Therefore, it is evident that patients with encephalitis can exhibit symptoms of upper respiratory tract infections. Moreover, some patients initially present with respiratory symptoms, such as a runny nose, before the viruses enter and infect the brain cells. Patients with encephalitis must receive timely treatment, primarily symptomatic treatment to prevent complications, along with antiviral medication for targeted treatment. Most patients have a good prognosis.

How is encephalitis diagnosed?

The diagnosis of encephalitis cannot rely solely on auxiliary examinations; it must depend on the patient's medical history, clinical manifestations, and corresponding physical examination. If a patient presents with fever, headache, nausea, vomiting, and signs of nuchal rigidity upon examination, the possibility of encephalitis should be considered. Additionally, severe cases of encephalitis may exhibit seizures, cognitive changes, and personality alterations. Auxiliary examinations mainly include three types: the first type is imaging studies, primarily brain MRI, which can clearly identify the specific areas of the brain affected and determine which brain lobe is damaged. The second important examination is an electroencephalogram (EEG), which can detect diffuse slow waves, especially a significant presence of delta waves, highly indicative of encephalitis. The third important auxiliary examination is lumbar puncture for cerebrospinal fluid analysis; an increase in white blood cells and protein in the cerebrospinal fluid also suggests inflammation within the skull. Therefore, the main auxiliary examinations for encephalitis include MRI, EEG, and lumbar puncture.

After-effects of encephalitis

Some more serious types of encephalitis may leave sequelae. For example, common ones like herpes simplex viral encephalitis and epidemic encephalitis B. A minority of patients may suffer from certain degrees of sequelae, which typically include the following aspects. Firstly, some patients may experience secondary epileptic seizures, which present with loss of consciousness, limb convulsions, incontinence, and frothing at the mouth. These symptoms might require long-term oral medication for epilepsy. Secondly, another consequence of encephalitis is cognitive impairment in patients, characterized by significant reductions in computational ability, memory, and executive function. Additionally, some forms of encephalitis might leave patients with psychiatric symptoms, such as speaking incoherently.
