摘要
Sleep and waking EEG of 522 patients with epilepsy and various disease with attack nature were studied. EEG showed paroxysmal activities(PA) in 217 cases. PA appeared only during sleep in 96 cases. Posi- tive rate of EEG diagnosis increased from 23. 2 percent in waking recordings to 41. 6 percent. Fifty of 97 benign childhood epilepsy with centrotemporal spike(51. 6% ) had focal PA only during sleep. Two of 6 cases with Lennox-Gastaut syndrome showed tonic seizure and/or generalized paroxysmal fast activities, Seizure types of 15 patients were defined by interictal PA and letal EEG during sleep. There was no corre- sponding relationship between seizure time(waking or sleep) and PA sensitivity to state of vigilance.
