脑电图的癫样放电与癫发作有高度相关性。发作间期的癫样放电常提示脑内有癫刺激区 (ｉｒｒｉｔａｔｉｖｅｚｏｎｅ)。但有些人从未出现过癫发作或仅偶然有癫发作 ,脑电图却长时间存在数量不等的癫样放电 ,特别是在睡眠期。仅有脑电图上的癫样放电而不引起临床 Epileptiform discharges of EEG are highly correlated with epileptic seizures. Epileptic seizures during interictal seizures often indicate an irritative zone in the brain. But some people have never had epileptic seizures or occasional epileptic seizures, but epileptiform discharges of varying durations have been found in the EEG, especially during sleep. Only epileptiform discharges on the EEG did not cause clinical problems
