Evaluation of New Onset Seizures T2 Rudolph's Pediatrics, 22e YR 2011 FD 2011 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-149723-7 LK accesspediatrics.mhmedical.com/content.aspx?aid=7057903 RD 2024/03/28 AB A child’s first seizure is most often a brief, less than 5 minutes in duration, generalized convulsion that is justifiably concerning to physicians and parents. The overall incidence of a single unprovoked seizure approximates 60 per 100,000 persons/year with a peak incidence in the first year of life approximating 130 per 100,000 persons/year.1 In some instances, the first seizure is provoked by an underlying acute illness. In others, it is a manifestation of a chronic syndrome. In about half of the cases, a seizure recurs and the child meets diagnostic criteria for epilepsy.2 Accordingly, the evaluation of a new-onset seizure is centered on identifying its cause and predicting likelihood of recurrence.
