ABSTRACT

Objective: To evaluate the sleep-epilepsy relationship in patients with refractory complex partial seizures (CPS) that were considered potential candidates to surgical treatment. Subjects and methods: We evaluated the seizures occurrence in the waking and sleeping states during sessions of continuous V-EEG, in 41 patients with refractory complex partial seizures subjected to a program of presurgical evaluation in the CIREN. Results: According to the characteristics of the EEG at ictal start, 160 seizures were categorized in 22 patients as temporal, and 507 seizures corresponding to 14 patients were classified non-temporal. There was relationship dependence between the localization of the ictal EEG and the seizures proportion per days of monitoring as much for the seizures in vigil as for those that began during sleep. It was significant the seizures prevalence with beginning during sleep in the non-temporal epileptic group, as compared with temporal epileptic patients. It was estimated; however that 70% of the patients with temporal seizures had an ictal event at least during the V -EEG session initiated during sleep. Conclusions: Despite the prevalence of seizures during sleep in the extratemporal group, 70% of the patients with temporal seizures had an ictal event at least during the V-EEG monitoring sessions that initiated during sleep, which allows endorsing the clinical utility of the continuous V-EEG in the presurgical evaluation of patient with suspicion of TLE.
