Encephalitis in children is usually encephalitis caused by viruses, bacteria and other pathogens, and it is more common for encephalitis to present with crying. This is because viral encephalitis can lead to fever, headache and other uncomfortable symptoms in children. Encephalitis in children is mainly caused by pathogens entering the intestinal tract or respiratory tract and other channels to enter the bloodstream to multiply, and then infecting the skull through the bloodstream, causing fever, even convulsions, as well as increased intracranial pressure, which can lead to head pain, vomiting and so on, so the child will cry and scream. In severe cases, muscle spasms or tonic seizures may also occur, as well as coma. Encephalitis is very damaging to the brain, and especially severe encephalitis can cause acute death and sequelae. Therefore, children with encephalitis should be taken seriously, and it is recommended that they seek medical attention in a timely manner, follow the doctor’s instructions to carry out relevant examinations, and carry out targeted treatment or therapy with the help of the doctor.
