<p> 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</p>
