All of the following factors are associated with a substantially greater risk of developing epilepsy after febrile seizures, except:
All of the following factors are associated with a substantially greater risk of developing epilepsy after febrile seizures, except:
Show Hint
Separate the risk of recurrence from the risk of true epilepsy; early onset predicts recurrence.
Updated On: Jun 24, 2026
- Complex febrile seizures
- Early age of onset
- Developmental abnormalities
- Positive family history of epilepsy
Show Solution
The Correct Option is B
Solution and Explanation
The wording forces a careful distinction. After a febrile seizure two separate outcomes are tracked: another febrile seizure (recurrence) versus genuine epilepsy with unprovoked fits. This stem asks specifically about progressing to epilepsy.
The recognized predictors of later epilepsy are a triad: complex or atypical febrile seizures, an underlying neurodevelopmental abnormality, and a family history of epilepsy. Whenever one of these is present, the chance of true epilepsy climbs notably.
Early age of onset does not belong to that triad. A young age at the first febrile seizure predicts that febrile seizures will happen again, but it does not, on its own, push the child toward epilepsy. That mismatch makes it the exception the question is after, which is why option B is the answer.
The other three each carry a clear epilepsy link and therefore stay on the risk list. So the odd one out is early age of onset.
\[\boxed{\text{Early age of onset}}\]
