Abstract

Background: A good history and a standard EEG recording help establish most of the epilepsy syndromes.

Objective: The objective of this study was to establish different epilepsy syndromes on the basis of history and EEG in the clinically suspected seizure events.

Methodology: This cross-sectional study was carried out in the neurophysiology laboratory of National Institute of Neurosciences & Hospital, Dhaka, Bangladesh from January 2013 to December 2015, which included 2549 patients. EEG was obtained through surface scalp electrodes according to international 10/20 system. Patient and their attendants were interviewed using a semi structured questionnaire. The EEG findings, clinical history and in appropriate cases the neuroimaging, CSF and hematological findings were then correlated.

Result: Among the 2549 patients most were children (39.8% less than 10 years old) and young adult (30.63% in 11 to 20 years age group). Male patients outnumbered female (63% and 36 % respectively). The overall sensitivity of EEG in yielding abnormal interictal epileptiform discharges was 42%. About 32% of total 2549 patients were diagnosed as localization-related epilepsy (LRE), 5% idiopathic generalized epilepsy (IGE), 1.41% was Epileptic encephalopathy.

Conclusion: In conclusion EEG is helpful in classifying the types of seizure, aids in defining the epilepsy syndrome, predicting the outcome and assists in management of patients.
