Recurrence rate of seizure following discontinuation of anti-epileptic drugs in patients with normal long term electroencephalography.

This article is from Annals of Indian Academy of Neurology , volume 17 . Abstract Background:: The usefulness of electroencephalography (EEG) in predicting seizure recurrence after antiepileptic drugs (AED) tapering is a controversial subject. There have been no studies which tested the additional yield of long-term over routine EEG recordings in predicting seizure recurrence after AED withdrawal. Objective:: The primary objective of our study is to determine the recurrence rate of seizure following AED withdrawal in patients with focal epilepsy, unknown cause who had normal long-term electroencephalography (LTEEG) and secondary objective is to analyze the variables that would predict seizure recurrence. Materials and Methods:: This was a prospective observational study. A total of 91 patients were included. 62 patients who had normal routine and LTEEG entered the final phase of the study were followed-up regularly for 1 year or until seizure recurrence whichever was earlier. Results:: A total number of 91 patients were enrolled for the first phase of the study. Of these, 13 (14.29%) patients had an abnormal routine EEG. Of the remaining patients, another 16 (17.58%) had abnormal L
