摘要

癫痫痉挛是婴幼儿期癫痫的一种独特表现,与年龄有关,通常是婴儿癫痫痉挛综合征的一部分。癫痫性痉挛患儿可能会出现发育停滞和随后的衰退,部分原因是大量高幅发作间期癫痫样和慢波异常。癫痫性痉挛的早期识别和治疗,以及脑电图(EEG)结果的逆转,对于改善预后至关重要。识别hypsarrhythmia及其变异是确诊的关键。心律失常的各种模式并不具有病因特异性,但可以显示疾病的严重程度。目前已提出了几种评分系统,以提高识别心律失常的评分者之间的可靠性,并评估脑电图对治疗的反应。痉挛时的间期模式很短暂,由慢波、尖锐瞬时波、快速活动波和电压衰减波组成,可以是单独的波形,更常见的是这些波形的组合。间期模式通常是弥漫性的,但在结构性病因的患儿中可能会偏向一侧大脑半球。一部分癫痫痉挛患者的病因可通过手术治愈,大多数病例的神经影像学检查很容易发现病灶。癫痫痉挛不对称、并发局灶性癫痫发作、发作间期和发作期脑电图检查结果不对称都可能出现,但电生理检查结果缺乏病灶的情况并不少见。有学者描述了癫痫痉挛的颅内脑电图特征,但对于磁共振成像有明显局灶性致痫病灶的手术候选者,颅内脑电图监测的实用性值得怀疑,手术可通过无创数据进行。

Electroclinical Features of Infantile Epileptic Spasms Syndrome.

Epileptic spasms are a unique, age-dependent manifestation of epilepsies in infancy and early childhood, commonly occurring as part of infantile epileptic spasms syndrome. Developmental stagnation and subsequent decline may occur in children with epileptic spasms, partly due to the abundant high-amplitude interictal epileptiform and slow wave abnormalities. Early recognition and treatment of epileptic spasms, along with the reversal of the electroencephalography (EEG) findings, are critical for improving outcomes. Recognizing hypsarrhythmia and its variations is key to confirming the diagnosis. The various patterns of hypsarrhythmia are not etiology specific, but could indicate the severity of the disease. Several scoring systems have been proposed to improve the inter-rater reliability of recognizing hypsarrhythmia and to assess EEG progress in response to treatment. Ictal patterns during spasms are brief and composed of slow waves, sharp transients, fast activity, and voltage attenuation, either in isolation or more commonly as a combination of these waveforms. Ictal patterns are commonly diffuse, but may be lateralized to one hemisphere in children with structural etiology. A subset of patients with epileptic spasms has a surgically remediable etiology, with readily identifiable lesions on neuroimaging in most cases. Asymmetry in epileptic spasms, concurrent focal seizures, and asymmetric interictal and ictal EEG findings may be present, but a lack of focality in electrophysiological findings is not uncommon. Intracranial EEG features of epileptic spasms have been described, but the utility of intracranial EEG monitoring in surgical candidates with overt focal epileptogenic lesions on magnetic resonance imaging is questionable, and surgery could be performed using noninvasive data.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
