Patient's question:
What is a febrile seizureDoctor's answer:
Febrile seizures are a common emergency symptom of central nervous system dysfunction in children, more prevalent in infants and young children, with an onset age range of 6 months to 5 years, peaking between 9 months and 20 months. The incidence rate is approximately 2% to 4%, ranging from 2% to 5% in Europe and America. Most febrile seizures are caused by various infectious diseases, with upper respiratory infections being the most frequent. The typical clinical manifestations of an episode include sudden loss of consciousness, often accompanied by upward rolling of the eyeballs, staring or strabismus, facial muscle or limb rigidity, spasms, or continuous twitching. The duration of an episode can range from several seconds to a few minutes, sometimes recurring multiple times, even progressing into a continuous state. Severe febrile seizures may leave behind neurological sequelae.
