Abstract
Sleep is known to be severely altered in temporal lobe epilepsy (TLE). Furthermore, sleep deprivation is one of the key factors contributing to cognitive deficits and drug resistance in TLE. In the past, “non-ictal” parasomnias, as well as parasomnia-like nocturnal episodes ultimately diagnosed as seizures, have been documented in epileptic patients. However, recurrence of possibly “ictal” parasomnias in TLE has not been adequately appreciated. Through questionnaires and diaries distributed to TLE patients and their families in a tertiary center for epilepsy, 20 out of 168 patients seen in the last 2 years have been identified as, probands and extensively recorded during sleep. Patients presented with confusional arousals were 16, 14 with nightmares, and 2 with sleep walking episodes. Episodes (25) corresponding to clinical or subclinical seizures have been video-polygraphically recorded in 10/20 patients. Therapy optimization, pharmacological or surgical, resolved the episodes in 17/20 patients. A better seizure control with improved quality of life can be achieved by increasing and extending the practice of nocturnal recording in TLE patients.
