Podcast #311: Recurrence of Seizures in Pediatrics

Author: Aaron Lessen, M.D.

Educational Pearls:

• Recurrence rate for first time unprovoked seizures - 5% after 48 hours, 14% at 2 weeks , 30% after 4 months.
• Higher risk for recurrence: age under 3; patients with multiple seizures at initial presentation, focal neurologic findings on initial presentation.
• Useful for counseling patients and recommending follow up.
