Correct answer: C — Provoked (acute symptomatic) seizures do not constitute epilepsy, have a lower recurrence risk than unprovoked seizures, do not usually require long-term AED treatment, and have different DVLA implications

The distinction between provoked and unprovoked seizures is clinically important: (1) provoked seizures occur in the context of an acute precipitant (metabolic, toxic, structural) and have a much lower recurrence risk (~3–10%) once the precipitant is addressed; (2) they do not constitute epilepsy (which requires ≥2 unprovoked seizures or 1 unprovoked seizure with high recurrence risk); (3) long-term AED is usually not needed; (4) DVLA rules differ — for Group 1, driving may resume once the provoking factor has been addressed and is unlikely to recur. A: The distinction is very important. C: Long-term AED is usually not needed. D: Recurrence risk is much lower. E: SUDEP risk is predominantly in epilepsy with uncontrolled GTCS.
