Background: Sometimes children are referred to the EEG lab without overt seizures but with wide array of features of delayed developmental domains like motor delay, cognitive delay, speech and communication delay, visual impairment, hearing impairment. A detailed history and physical examination are most important for the diagnosis. EEG is done to identify the background dysfunction and the cases of Epilepsy. Aim of the study: To see the background function and the cases of Epilepsy through EEGs children presenting with delayed developmental domains. Method: Retrospective analysis was done from the EEG records during a 1year period (ie, 2015). 537 cases were identified with developmental delay but not having overt seizure. Their EEG findings were compared with history and clinical presentation. Results: In this study, 41.7% presented with speech communication problems, 32.4% with cognitive delay, 10.6% with hearing impairment, 8.8% came with motor delay and 6.5% with visual impairment. EEG of 29.5% showed abnormal features. These included 15% with features of focal discharges, 7% with generalized epileptiform discharges, 0.5% with multifocal epileptic form discharges, 2% with features of epileptic encephalopathy, 3% with features of generalized encephalopathy, 2 children with diffuse encephalopathy, and 5 children with non-specific dysfunction, 4 children with generalized low amplitude activities. Conclusion: EEG abnormalities were found in over one-third of the referred children based upon which important decisions could be taken for appropriate diagnosis and management.
