For Febrile Seizures: Recurrence Risk and Long-Term Prognosis, use the highest-yield facts to drive concrete treatment decisions. Pay particular attention to 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.
