Febrile convulsions FC or febrile seizures are common in children aged 6 months to 5 years who have a body temperature of or above 38 °C (100.4 °F) with the absence of an underlying CNS abnormality. This study aims to assess parental knowledge, attitude, and practice toward febrile convulsions while also Identifying the sociodemographic factors associated with the level of knowledge of parents in the Kingdom of Saudi Arabia. This is a cross-sectional study that was conducted in all regions of the Kingdom of Saudi Arabia. A self-administered online questionnaire was distributed amongst Saudi parents who have one or more children. All statistical analyses were carried out using Statistical Package for Social Sciences Version 20. The survey found that 44.2% of respondents reported having a child who was five years old or younger, with 19.1% reporting that their child had experienced a febrile seizure. The majority of respondents (59.9%) selected fever and the child's age as a cause, while 49.7% selected abnormal electrical currents in the brain, and 39.7% selected hereditary factors. Only 14.7% of participants had high knowledge scores of febrile convulsions, 28.7% had moderate knowledge, and 56.6% had low knowledge scores. In conclusion, understanding the knowledge, attitudes, and practices regarding febrile convulsions among Saudi parents is crucial for improving the management of this common childhood condition.
