ETIOLOGY AND EPIDEMIOLOGY OF FEBRILE SEIZURE - LITERATURE REVIEW

Introduction:The febrile convulsive crisis is the most common convulsive crisis in childhood, with an approximate incidence of 2 to 5% of infants and preschoolers, and may or may not present with neurological sequelae. 1.Goal: Due to the importance of the epidemiology and etiology of this condition, this article aims to describe them.Method: The search was carried out in the PubMed, BVS and Scielo databases, and was limited to articles between the period 2019 to 2023 that met the criteria of being literature reviews and case reports.Result: It is essential to understand the difference between febrile seizures and epileptic seizures in the presence of fever. 2 .The risk of recurrence of the febrile crisis in other infectious processes is 30%, that is, children who had a seizure with fever may have a second episode 2 .The hyperthermia observed during infectious processes can reduce the seizure threshold and, in addition, the predominance of excitatory neurotransmitters, cytokines and the genetic pattern are all mechanisms that make the infant brain more vulnerable to triggering seizures in the presence of infection 7 .
