What is the most common cause of seizures in children?

The most common cause of seizures in children is an abrupt rise in body temperature, often related to febrile seizures. These seizures frequently occur in young children, typically between the ages of six months and five years, during a rapid increase in fever, commonly associated with viral infections. The mechanism behind febrile seizures is thought to be linked to the body's response to an infection and how quickly the temperature escalates, rather than the absolute temperature itself.

While a life-threatening infection can cause seizures, and high fevers are certainly a factor, it is the rate at which the temperature increases that is a critical trigger for febrile seizures. Children might experience a seizure even if their fever is below 102°F, as it is the change in temperature that impacts their neurological function.

In summary, understanding the relationship between the rapid rise in temperature and the occurrence of seizures is key. This highlights why recognizing febrile seizures is essential for immediate care and reassurance for caregivers, as these seizures are usually benign and self-limiting in nature.
