Abstract

Objective: We investigated how diagnosis and injury location on neonatal brain MRI following onset of acute provoked seizures was associated with short term outcome. Study design: A multicenter cohort of neonates with acute provoked seizures enrolled in the Neonatal Seizure Registry. MRIs were centrally evaluated by a neuroradiologist for location of injury and radiologic diagnosis. Clinical outcomes were determined by chart review. Multivariate logistic regression was used to examine the association between MRI findings and outcomes. Results: Among 236 newborns with MRI at median age 4 days (IQR 3–8), 91% had abnormal MRI. Radiologic diagnoses of intracranial hemorrhage (OR 3.2 [1.6–6.5], p < 0.001) and hypoxic-ischemic encephalopathy (OR 2.7 [1.4–5.4], p < 0.003) were associated with high seizure burden. Radiologic signs of intracranial infection were associated with abnormal neurologic examination at discharge (OR 3.9 [1.3–11.6], p < 0.01). Conclusion: Findings on initial MRI can help with expectant counseling on short-term outcomes following acute provoked neonatal seizures.
