Ophthalmol Update Jan ;16(2):655-8.

Objective: To determine the frequency of interictal epileptiform discharges and its common types in patient with new onset epilepsy Place & Duration: Department of Neurology, Lady Reading Hospital, Peshawar from January`2012 to July`2012. Materials and Methods: A total of 177 patients (64.4% males and 35.6% females), with mean age of 18.61 years (± 13.28 SD) years who were managed in OPD or indoor according to their condition. History, physical examination, routine investigations and EEG were carried out for all patients. Mean and standard deviation of age, frequencies, percentages of gender, time of presentation, IEDs and its common types were calculated using SPSS-20. Results: The time of presentation was 24-48 hours in 164 (92.7%), 48-72 hours in 9 (5.1%) and 72 hour-1week in 4 (2.3%) of patients. Epileptiform activity was found in 117 (66.1%). The sharp wave was present in 101 (57.1 %), spike wave in 42 (23.7%), spike and wave in 29 (16.4%), multiple spike complex in 20 (11.3), and multiple spike and slow wave complex in 19 (10.7%) of patients. The IED and its types were also stratified among age, gender and time of presentation to see the effect modifications. Conclusion: IEDs are present in 66.1% of epileptic patients. Sharp waves are most common amongst IEDs followed by spike, spike and wave, multiple spike complex, and multiple spikes and slow wave complex.
