Abstract:
It has been known that sleep and epilepsy have strong mutual influence and many reports have emphasized the imortance of the EEG recording during sleep in epileptic patients. We analyzed waking and sleep EEGs of 153 consecutive cases of epileptic patients. Waking and sleep recordings were perforrned in succession during 26 minutes. Sleep induction method was 24 to 26 hour sleep deprivation. Most of the sleep recordings consisted of stage 1 and stage 2 sleep. 134 patients had localization-related epilepsy including 23 cases of benign rolandic epilepsy and benign epilepsy with occipital paroxysms, and 19 patients had generalized epilepsy. Ninty-two cases showed definite epileptiform discharges and 37 patients including 30 cases of complex partial seizure disorder had all their epileptiform discharges detected only during sleep state. The epileptiforrn discharges of 43 patients were detected on both waking and sleep recordings and underwent modifications of focalization, synchronization, generalization and the appearance of independent spikes during sleep state.
