Which potential cause of Ian's seizure is associated with a fever?

• A. Head injury
• B. Febrile seizure
• C. Ingestion of poison
• D. Idiopathic seizure

Answer: (B)

Febrile seizures are specifically associated with fever, particularly in young children. These seizures typically occur in the context of rising body temperature due to an illness, such as a viral infection. They are generally seen in children between the ages of 6 months and 5 years and are often benign, meaning that they usually do not result in long-term complications or indicate a serious underlying condition.

The occurrence of a seizure during a fever is common and often results from the rapid change in body temperature rather than any structural brain abnormality or metabolic issue. Knowing that Ian has a fever would make febrile seizures a likely explanation for the seizure event.

Other causes such as head injury, ingestion of poison, or idiopathic seizures do not directly relate to the presence of fever and would point toward different diagnostic considerations. Therefore, the association of fever with the seizure makes febrile seizure the most fitting answer in this context.
