An increase in spike frequency does not help clinicians predict the outcome of surgery in patients with temporal lobe epilepsy. To reach that conclusion, researchers used scalp video monitoring data from patients who had anterior temporal lobe epilepsy to look for interictal epileptiform abnormalities, comparing patients with more than 60 spikes/hour to those with fewer spikes. They found no significant differences in seizure outcomes among patients who had undergone anterior temporal lobectomy.
