What is a common cause of febrile seizures in young children?

1. Rapid temperature increase

2. Genetic predisposition

3. Previous history of seizures

4. Exposure to allergens

The correct answer is: Rapid temperature increase

A common cause of febrile seizures in young children is indeed a rapid temperature increase. Febrile seizures typically occur in children between the ages of six months and five years, often in response to a sudden rise in body temperature due to illnesses like viral infections or other fever-inducing conditions. When the body temperature rises quickly, particularly when it elevates above 100.4°F (38°C), it can disrupt the normal activity of the brain, leading to a seizure. While genetic predisposition and a previous history of seizures can influence the likelihood of experiencing seizures, they are not specific causes of febrile seizures themselves. Exposure to allergens may lead to other medical issues, like allergic reactions, but it does not typically relate to the onset of febrile seizures caused by fever. Thus, the rapid increase in temperature directly triggers these seizures, making it the most relevant and accurate answer in this context.
