Prognostic value of EEG depression in preterm infants for later development of cerebral palsy

Area of Science:

• Neonatal Neurology
• Neurodevelopmental Pediatrics
• Clinical Neurophysiology

Background:

• Preterm infants face risks of neurodevelopmental disorders, including cerebral palsy (CP).
• Electroencephalography (EEG) is a key tool for assessing brain function in neonates.
• Predicting CP risk early is crucial for timely intervention and improved outcomes.

Purpose of the Study:

• To determine the optimal timing for EEG recordings to predict cerebral palsy (CP) risk in preterm infants.
• To correlate the degree of acute stage abnormalities (ASA) on initial EEG with psychomotor outcomes.

Main Methods:

• Retrospective analysis of EEG recordings from 295 preterm infants (27-32 weeks gestational age).
• Initial EEG recordings were performed within 7 days of life.
• Correlation analysis between ASA grade and CP diagnosis/severity at 18 months corrected age.

Main Results:

• The maximum degree of ASA correlated with CP development and severity.
• Correlation between ASA and CP severity was highest on days 1-2 post-birth, decreasing after day 3.
• EEG on day 1 or 2 showed higher positive predictive value and better correlation with CP severity.

Conclusions:

• EEG performed on day 1 or 2 of life is most useful for predicting CP risk and severity in preterm infants based on ASA.
• Early EEG assessment can aid in identifying infants at high risk for CP.
• Timing of EEG is critical for maximizing its predictive value in preterm infants.
