Prognostic significance of independent auras in temporal lobe seizures.

Abstract
We performed a retrospective study of auras that occurred independently of complex partial seizures in patients undergoing continuous EEG monitoring with stereotactically implanted depth electrodes placed in mesiotemporal structures. Forty of 54 patients had a history of independent auras, and 32 of these individuals had independent auras while being monitored. Two hundred ninety-two independent auras were recorded, and EEG characteristics and subjective symptoms were analyzed with regard to surgical outcome. Most patients had ictal EEG changes with all or some of their auras. Four patients had nonlocalized or multifocal complex partial seizures despite the presence of well-localized auras, indicating that if intracranial ictal recording is used as a gold standard for localization, complex partial seizures must be recorded. Presence or absence of EEG change with auras did not affect prognosis nor did variability of ictal EEG pattern, spatial extent of initial field potential, aura duration, or character of symptoms correlate with prognosis or postoperative persistence of auras.
