Abstract
Correlation between time to first scalp EEG seizure during video/EEG telemetry and self-reported seizure frequency was determined in refractory epilepsy patients. Eighty two consecutive epilepsy patients were preoperatively evaluated, as part of a larger study, during their video/EEG monitoring at the Adult Epilepsy Center at Washington University. Self-reported seizure frequency, time to first seizure in the monitoring unit, and clinical variables of age, sex and seizure focus localization were analyzed. Mean age of the patients was 35±11 years and 54.9% were women. In 51 patients with temporal and 19 patients with extra temporal epilepsy, the mean time to first scalp EEG seizure was 44±48 h. Self-reported seizure frequency did not predict the time to first scalp EEG seizure in the seizure monitoring unit. The majority of patients had their first scalp EEG seizure during the first two days of video/EEG telemetry. Self-reported seizure frequency was a poor predictor of time to first scalp EEG seizure. This finding suggests that patients with less frequent self-reported seizure rates should also be considered as good candidates for further evaluation, including scalp and intracranial video/EEG telemetry.
