The idiopathic generalized epilepsies of childhood form a heterogeneous group of epileptic syndromes, with certain clinical and electroencephalographic characteristics in common. From the onset, the seizures affect both cerebral hemispheres with generalized clinical expression and from the start there are bilateral electroencephalographic patterns during seizures. These epilepsies have no known causes, there is a genetic predisposition and relation to the age of onset. The electroencephalographic characteristics during and between seizures have points in common: the basal electroencephalographic activity is normal in all the epilepsies of this group, the paroxystic anomalies are generalized, synchronic and symmetrical, and are formed of bilateral discharges of spikes, multiple spikes, spikes and waves and multiple spikes and waves, with discharges at a frequency of 3 Hz or more.
In this article we review the electroencephalographic characteristics during and between seizures of the idiopathic generalized epilepsies and epileptic syndromes of childhood, with particular emphasis on childhood absences, since we consider this to be the commonest and most representative of the idiopathic generalized epilepsies of infancy.
We consider that the electroencephalographic aspects of epilepsies and the epileptic syndromes make up a factor of great importance as a help in confirmation in diagnosis.
儿童特发性全身性癫痫是一组异质性癫痫综合征，具有某些共同的临床和脑电图特征。从发病开始，发作累及双侧大脑半球，临床表现为全身性，发作时脑电图呈现双侧模式。这些癫痫病因不明，存在遗传易感性且与发病年龄有关。发作期及发作间期的脑电图特征有共同之处：该组所有癫痫的基础脑电图活动均正常，发作性异常为全身性、同步性和对称性，由双侧棘波、多棘波、棘慢波和多棘慢波放电组成，放电频率为3Hz或更高。
在本文中，我们回顾了儿童特发性全身性癫痫和癫痫综合征发作期及发作间期的脑电图特征，特别强调儿童失神癫痫，因为我们认为它是婴儿期特发性全身性癫痫中最常见和最具代表性的类型。
我们认为癫痫和癫痫综合征的脑电图表现是诊断中非常重要的辅助确诊因素。
