Encephalitis convulsions usually present as generalized tonic convulsions, often with loss of consciousness, hands leaning toward the palms of the hands and a corkscrew-like appearance, and may be accompanied by foaming at the mouth and clenching of the teeth, easily causing tongue bite or obstruction of the airway leading to apnea, which may be accompanied by incontinence, recurrent high fever, and twitching of the limbs, usually caused by damage to the cerebral cortex due to encephalitis. Encephalitis is an infectious disease of the central nervous system caused by pathogens infecting the brain parenchyma, some of which are somewhat contagious. In addition to convulsions, patients may experience fever, varying degrees of impaired consciousness, headache, body pain, weakness, nausea, vomiting, and in severe cases, coma or even death. Once the symptoms of encephalitis appear, it is important to go to the hospital promptly to avoid delayed treatment that may lead to serious sequelae or even life-threatening effects. Viral infections that cause encephalitis are treated with antiviral drugs such as acyclovir or ganciclovir. For encephalitis caused by other pathogens, anti-infective treatment is required depending on the specific pathogen.
