Cumulative effect of vagus nerve stimulators on intractable seizures observed over a period of 3years.
The objective of the study was to evaluate the efficacy of vagus nerve stimulator (VNS) therapy and identify factors associated with reduction of seizures. The VNS is an accepted therapeutic option for patients with refractory partial epilepsy. There are, however, limited data regarding efficacy in any specific group of patients with epilepsy. ⋯ Significant reductions in seizure frequency were noted with VNS therapy over a 3-year follow-up period with a possible cumulative effect. Lateralization or localization of epileptic focus or epilepsy subtype did not correlate with response to VNSs.

Persons with epilepsy experience déjà vu phenomena with or without seizure recognition. Déjà vu experiences are also common mental phenomena in nonclinical individuals. The purpose of this study was to clarify two forms of déjà vu experiences in persons with epilepsy. ⋯ The NSR form was significantly associated with idiopathic generalized epilepsies, less frequent antiepileptic drug administration, and no mesial temporal sclerosis. Although there was a significant association between the frequency of the SR form and patients' habitual seizures, the frequency of the NSR form was not associated with the frequency of the patients' habitual seizures. Persons with epilepsy experience two forms of déjà vu which are differently associated with their seizure recognition.
