综述的目的：癫痫是一种异质性疾病，通常与异常脑电图（EEG）结果相关。本文概述了癫痫性疾病的常见脑电图结果。讨论了脑电图和颅内脑电图研究的生理学基础。最近发现：脑电图在临床实践中得到了广泛的应用。由于发作性疾病的发作性，当脑电图未捕捉到习惯性发作时，间断性癫痫样放电（如尖峰和尖波）常被用于支持癫痫的诊断。间歇期和间歇期脑电图结果也是癫痫发作和癫痫分类的基础。持续重症监护脑电图监测已成为诊断和治疗亚临床癫痫发作和非惊厥性癫痫持续状态的宝贵研究。当癫痫手术需要定位癫痫病灶和绘制相关脑区时，硬脑膜下或脑实质内电极的颅内脑电图是必要的。摘要：脑电图是诊断癫痫的重要工具。发作间期和发作期脑电图结果对癫痫疾病的确认和分类至关重要。颅内脑电图监测对于一些患者的手术计划也是不可或缺的。
PURPOSE OF REVIEW: Epilepsy is a heterogeneous disorder that is often associated with abnormal electroencephalogram (EEG) findings. This article provides an overview of common EEG findings in epileptic disorders. The physiologic basis of EEG and intracranial EEG studies is also discussed.RECENT FINDINGS: EEG is widely used in clinical practice. Because of the paroxysmal nature of seizure disorders, interictal epileptiform discharges, such as spikes and sharp waves, are often used to support the diagnosis of epilepsy when a habitual seizure is not captured by EEG. Interictal and ictal EEG findings also underlie the classification of seizures and epilepsy. Continuous critical care EEG monitoring has become an invaluable study in the diagnosis and treatment of subclinical seizures and nonconvulsive status epilepticus. Intracranial EEG with subdural or intraparenchymal electrodes is warranted when localization of the seizure focus and mapping of eloquent brain areas are required to plan epilepsy surgery.SUMMARY: The EEG is a key tool in the diagnosis of epilepsy. Interictal and ictal EEG findings are crucial for the confirmation and classification of seizure disorders. Intracranial EEG monitoring is also indispensable for planning surgery for some patients.
