Children with viral encephalitis may have headaches after they are cured. Viral encephalitis is mainly caused by viral infections, and during the exacerbation of the disease, it often causes acute symptoms such as headache, fever, vomiting, etc., which need to be actively treated with antiviral therapy, and the headache symptoms will usually be relieved or gradually disappear after the cure. If children still have headaches, it is not because of the sequelae of viral encephalitis, but mainly because they have not fully recovered. Although the encephalitis has improved, it takes some time for the brain nerve cells to repair. If a child is currently experiencing headaches, he or she should work with his or her doctor to take nerve-nourishing medications, such as vitamin B6. Children with viral encephalitis who develop headaches after they have recovered should be seen by a doctor to find out the cause.
