Abstract |
|---|
The characteristics of seizures and epilepsy in infants who have had an apparent life-threatening event (ALTE) have been poorly defined. Our objective was to characterize in-depth the cohort of ALTE patients who developed seizures. We collected data from infants hospitalized for an ALTE, and evaluated patients for subsequent seizures or chronic epilepsy. Of 471 ALTE patients, 25 (5.3%) had seizures, and 17 (3.6%) developed chronic epilepsy. There was no increased risk for febrile seizures. Abnormal brain MRI results and developmental delay were only found in those patients who developed chronic epilepsy. Of those who developed chronic epilepsy, 47% were diagnosed with seizures within 1 week of their ALTE. The discharge diagnosis at the time of the ALTE was poorly predictive of those who developed seizures. In most cases the cause of chronic epilepsy was unknown, although cortical dysplasias made up a significant percentage (12%).
