A scoring system to predict outcome following neonatal seizures.

Ninety-six newborn infants with seizures were scored during the initial hospitalization on abnormality of EEG, neurologic examination, etiology of seizures, length of seizure, type of seizure, and birth weight under or over 1,500 gm. At 3 months, corrected for gestational age, the 80 surviving infants were scored on abnormality of current EEG, neurologic examination, etiology of seizure, presence or absence of seizure since hospital discharge, and birth weight under or over 1,500 gm. At age 10 months, 76 of 77 surviving infants were evaluated with the Gesell Developmental Inventory, physical examination, and neurologic examination. Chi square analysis documented that the scoring system was an accurate predictor of those infants with seizure disorders, mental retardation, and motor dysfunction. The score may assist the clinician in making decisions in regard to anticonvulsant therapy during initial hospitalization or at age 3 months.
