The authors are from the University of Texas at Houston, Tulane University, Columbia Medical School (New York) and the Mayo Clinic.
Parameters:
(1) age of the child during episode
(2) history of febrile convulsions in first degree relatives
(3) complex features
Definitions:
(1) Multiple seizures within a 24 hour period was termed a single seizure with repeated episodes.
(2) Complex features included (a) focal seizure (not generalized); (b) duration > 10 minutes; (c) single seizure with repeated episodes
