ABSTRACT
BACKGROUND:
Periventricular leukomalacia (PVL) is a common brain injury in premature infants, and epilepsy remains a significant complication. One concerning electroencephalographic (EEG) pattern found is developmental and/or epileptic encephalopathy with spike-and-wave activation in sleep (DEE-SWAS). This pattern is associated with persistent neuropsychological and motor deficits, even without a diagnosis of epilepsy. The purpose of this study is to identify the relationships between various PVL grades and EEG patterns in this population on follow-up visits, especially the occurrence of DEE-SWAS pattern on EEG.METHODS:
This is a retrospective study of <36 weeks gestational age newborns who were followed in the neurodevelopmental clinic at Corewell Health East/Corewell Health Children's Hospital in Royal Oak, Michigan, between 2020 and 2022. Patients' demographics along with prematurity complications, diagnostic head ultrasound (HUS), and EEG studies were reviewed and graded. EEG studies are usually ordered when seizures were suspected.RESULTS:
A total of 155 newborns met the inclusion criteria. Twenty-six patients had PVL. Nine patients had grade 2 to 3 PVL based on HUS review. EEG was performed on 15 patients with PVL at a mean age of 22 months. More severe PVL grades were significantly associated with worse EEG patterns (P = 0.005). Five patients had DEE-SWAS pattern on EEG, all of whom had grade 2 or 3 PVL. Epilepsy was eventually diagnosed in three infants with PVL.CONCLUSIONS:
EEG can help identify important abnormal electrographic patterns in premature infants with PVL early in life; this might give a window of opportunity to intervene early and improve long-term developmental outcomes in this population.Palabras clave
