OBJECTIVE: The risk of developing @entity302 following @entity410 ( @entity410 ) varies between 2% and 10%, with @entity410 ( @entity410 ) having a higher risk. We examined the utility of detected @entity302 on the initial EEG following a first @entity410 in predicting subsequent @entity302 . METHODS: This was a retrospective study of consecutive @entity1 (ages 6-60months) who were @entity16 or mildly delayed, seen in the @entity2613 following a first @entity410 and had both an EEG and minimum of 2-year follow-up. Data regarding clinical characteristics, EEG report, development of subsequent @entity302 , and @entity302 were collected. Established clinical predictors for subsequent @entity302 in @entity1 with @entity410 and EEG status were evaluated for potential correlation with the development of subsequent @entity302 . Sensitivity, specificity, and positive and negative predictive values of an abnormal EEG (epileptiform EEG) were calculated. RESULTS: A group of 154 @entity1 met our inclusion criteria. Overall, 20 (13%) @entity1 developed @entity302 . The prevalence of @entity302 was 13% (CI 8.3-19.6%). @entity302 were noted in 21 @entity1 (13.6%), EEG slowing in 23 @entity1 (14.9%), and focal asymmetry in six (3.8%). Epileptiform EEGs were noted in 20% (4/20) of @entity1 with @entity302 and 13% (17/134) of @entity1 without @entity302 (p=0.48). At an estimated risk of subsequent @entity302 of 10% (from population-based studies of @entity1 with @entity410 ), we determined that the @entity2286 of an epileptiform EEG for subsequent @entity302 was 15%. None of the clinical variables (presence of more than 1 complex feature, family history of @entity302 , or @entity159 ) predicted @entity302 . CONCLUSIONS: An epileptiform EEG was not a sensitive measure and had a poor positive predictive value for the development of @entity302 among @entity16 or mildly delayed @entity1 with a first @entity410 . The practice of obtaining routine EEG for predicting @entity302 after the first @entity410 needs clarification by well-defined prospective studies.
