Corelation of Various Causes of Neonatal Seizures With Different Patterns of EEG Waveforms

Introduction: Electroencephalography, or EEG for short, is a non-invasive way to monitor brain activities. It is much helpful in seizures detection and quantification and for assessment of cortical activity. 3 In our study we aimed to correlate various causes of neonatal seizures with different patterns of EEG waveforms. Material and methods : the study was conducted in a tertiary care hospital in central India. 120 Full term neonates with clinical seizures were included in the study and an EEG analysis was done for these children. Results: clonic seizures(40%) were the most common type of seizures and birth asphyxia (70%)was the most common aetiology of clinical neonatal seizures. Metabolic causes (hypoglycaemia 71.4%and hypocalcaemia 74%) produced more number of normal , whereas birth asphyxia and meningitis(66.7% each) produced more number of abnormal waveforms on EEG. Conclusion : birth asphyxia and meningitis produce more number of abnormal waveforms on EEG in comparision to metabolic causes of neonatal seizures
