Symptoms of viral encephalitis in children?

summary

Acute viral encephalitis in children refers to primary encephalitis caused by direct invasion of brain parenchyma by virus. The disease occurs throughout the year, so it is also known as sporadic encephalitis. The common viruses causing encephalitis are enterovirus, simple cytomegalovirus, Myxovirus and other viruses. The main clinical manifestations are the symptoms of brain parenchymal damage and intracranial hypertension, such as fever, headache, vomiting, convulsions, and coma in severe cases. However, due to the location and scope of the virus invasion, the severity of the disease may vary, and the forms are also diverse. Symptoms of viral encephalitis in children? Let's talk about it.

Symptoms of viral encephalitis in children?

1. Infection symptoms: such as fever, general discomfort, myalgia and sore throat, which can range from several weeks to several weeks. In some cases, fever may occur suddenly, and white blood cells may be normal or increase to (15-30) × 109/L。

2. Meningeal stimulation sign and cerebrospinal fluid changes: the pressure of cerebrospinal fluid was normal or increased, and the white blood cells increased to (10-500) × 106 / L, a few up to (1000-1500) × 106 / L, mainly lymphocytes. In the early stage of arbovirus encephalitis, neutrophils are the main component. Sugar is normal or slightly higher, a few can be reduced. 5-1 g / L. there were red blood cells in cerebrospinal fluid of HSV encephalitis. Cerebrospinal fluid can be completely normal in a few cases of acute viral encephalitis.

3. The symptoms of localized or diffuse encephalitis include mental symptoms, delirium, coma and other disturbance of consciousness, convulsion, aphasia, strong grip, sucking reflex, hemiplegia. The tendon reflex was asymmetric and the pathological reflex was positive. Brain damage includes cerebral palsy and autonomic nervous system dysfunction. Cerebellar lesions include nystagmus, ataxia, and dyskinesia.

matters needing attention
