EEG Abnormalities as Predictor of Outcome in Pediatric Encephalopathy
Electroencephalographic (EEG) Abnormalities as a Predictor of Poor Outcome in Pediatric Encephalopathy
研究概览
详细说明
Pediatric encephalopathy has multiple etiologies and variable neurological outcomes. Early prognostic assessment is essential for clinical decision-making and family counseling. Electroencephalography (EEG) is a non-invasive tool that may help predict neurological outcome.
This prospective observational study will include children aged 1 month to 18 years with clinical diagnosis of encephalopathy. EEG will be performed within the first 48 hours of admission. Neurological outcome will be assessed at hospital discharge using the Pediatric Cerebral Performance Category (PCPC) scale. A PCPC score of 1-2 will be considered good outcome and a score of ≥3 will be considered poor outcome.
