For Febrile Seizures: Recurrence Risk and Long-Term Prognosis, focus on Age <18 months: highest recurrence risk; ~1/3 recur, 50% risk if 2 prior, Simple febrile seizure → 1-2% epilepsy risk (similar to general population), and Complex features (>15 min, >1 in 24h, focal): 6-8% epilepsy risk; 2+ risk factors → 10% when choosing therapy, counseling about risk, planning monitoring, and deciding when closer follow-up or escalation is needed.

Age &lt,18 months: highest recurrence risk, ~1/3 recur, 50% risk if 2 prior; Simple febrile seizure → 1-2% epilepsy risk (similar to general population); Complex features (&gt,15 min, &gt,1 in 24h, focal): 6-8% epilepsy risk, 2+ risk factors → 10%; Early seizures post-trauma → 25-35% develop late PTE; No long-term AED prophylaxis for simple febrile seizures (side effects outweigh benefit)
