儿童良性癫痫伴中央颞区棘波的研究进展

儿童良性癫痫伴中央颞区棘波(Benign childhood epilepsy with centrotemporal spikes,BECTS)是一种儿童时期发病的癫痫综合征,属于特发性局灶性癫痫,在所有儿童癫痫中约占8%～23%。其临床特征为局灶性发作,发作间期脑电图显示特征性的中央颞区棘波。目前关于儿童良性癫痫伴中央颞区棘波的病因及最佳诊疗方案尚未达成明确共识,本文对近年来该病相关研究作一综述,以期对该疾病的基础及临床研究提供一定参考。     

儿童良性癫痫伴中央颞区棘波患者发作期脑电图特点分析

目的了解儿童良性癫痫伴中央颞区棘波(benign epilepsy with centrotemporal spikes in children,BECT)的发作期脑电图。方法利用5a时间收集605例BECT患者的临床和脑电图资料。结果 30例患者出现30次癫痫发作。这些患者发作期EEG被分为4种发作期图形。最多的一种类型为A型,12例出现,低电压快节律棘波,波幅逐渐增高节律逐渐变慢。B型,7例次,棘波混合尖波频率和波幅逐渐增高。C型,6例次,θ波波幅逐渐增高和频率逐渐减慢。D型,5例次,局部电活动减弱,继之为前3型。结论虽发作间期BECT脑电图相似,均呈中央颞区放电,BECT发作期图形不是唯一不变的;发作前脑电图电抑制和发作后慢波比较常见,不影响BECT的诊断;发作前图形、发作中脑电图可以相互转化,不影响BECT的诊断。

Panayiotopoulos-type benign childhood occipital epilepsy: a prospective study

OBJECTIVE: To characterize the clinical and EEG features of the syndrome of benign childhood partial seizures with ictal vomiting and EEG occipital spikes (Panayiotopoulos syndrome [PS]). METHODS: Prospective study of children with normal general and neurologic examinations who had seizures with ictal vomiting and EEG with occipital spikes. RESULTS: From February 1990 to 1997, the authors found 66 patients with PS and 145 children with benign childhood epilepsy with centrotemporal spikes. Peak age at onset of PS was 5 years. Ictal deviation of the eyes and progression to generalized seizures were common. One-third had partial status epilepticus. During sleep, all had seizures. While awake, one-third also had seizures. Five children with PS had concurrent symptoms of rolandic epilepsy and another five developed rolandic seizures after remission of PS. Prognosis was excellent: one-third had a single seizure, one-half had two to five seizures, and only 4.5% had frequent seizures. CONCLUSIONS: Panayiotopoulos-type benign childhood occipital epilepsy is less common than benign childhood epilepsy with centrotemporal spikes but is well defined and recognizable by clinical and EEG features.     

Atypical Evolutions of Benign Localization‐Related Epilepsies in Children: Are They Predictable?

PURPOSE: To emphasize that, in some patients, different atypical evolutions occur in the course of so-called benign focal epilepsies of childhood (BFEC) and to promote interest in finding clinical and/or electroencephalographic (EEG) clues to which patients might be prone to these risky evolutions. METHODS: Twenty-six patients who started with the typical clinical and EEG features of benign childhood epilepsy with centrotemporal spikes (BCECTS) but who had reversible or persistent, serious epileptic events including status epilepticus and language, cognitive, or behavioral impairments were followed for 相似文献   

Benign partial epilepsy of childhood: a longitudinal neuropsychological and EEG study of cognitive function

The study combined prospective neuropsychological and EEG results of 22 children presenting with typical benign partial epilepsy with rolandic spikes (n=19) and occipital spikes (n=3). The aims were to assess the types of cognitive problems which may be encountered in this population, to evaluate the course of cognitive and learning capacities during the active phase of epilepsy, and to see if there was a correlation with paroxysmal activity on the EEG. Average age at entry in the study was 8.4 years and each child was seen two to four times over a period of 1 to 3 years. EEGs showed persistent spike foci in most cases that worsened in three cases, but there were no continuous spike-waves during sleep. No child had persistent stagnation, marked fluctuations, or a regression in cognitive abilities. Of 22 children, 21 had average IQ (>80). Eight children had school difficulties requiring special adjustment. No single cognitive profile was identified. Four children had delayed language development and eight children had transient weak scores in one isolated domain (verbal, visuospatial, memory) which improved or normalized during the course of the study with concomitant EEG improvement or normalization. In two of the three children with aggravation of the paroxysmal EEG activity, clinical changes were documented. A proportion of children with typical benign partial epilepsy with rolandic spikes showed mild, varied, and transient cognitive difficulties during the course of their epilepsy, and in most cases this probably had a direct relation with the paroxysmal EEG activity.     

Atypical BECTS and homocystinuria

Reported is an association of atypical benign childhood epilepsy with centrotemporal spikes (BECTS) and homocystinuria in three apparently healthy children with borderline intelligence, two of whom had difficult-to-control seizures. In all three, EEG were suggestive of BECTS, although the clinical features were not. Homocystinuria could not be diagnosed for several years, pending metabolic evaluation.     

Clinical and EEG characteristics of benign rolandic epilepsy in Chinese patients

We retrospectively evaluated the clinical and electroencephalogram (EEG) characteristics of benign rolandic epilepsy (BRE) in Chinese children. Two hundred and seventy-six patients with BRE were enrolled in this study. All patients had their first seizure between the ages of 3 and 12 years. 39.5% (109 cases) of patients ceased to have further BRE seizures by the age of 6 years, 93.1% (257 cases) recovered by the age of 12 years and 96.7% (267 cases) recovered by the age of 18 years. Two hundred and twenty-seven patients suffered only simple partial seizures, whereas 49 patients suffered generalized seizures from onset of BRE. The EEG scans of 239 patients showed repetitive diphasic spikes or sharp waves with high amplitude, which were most dominant in the central or centrotemporal areas. The spikes were confined to one hemisphere in 180 patients and occurred bilaterally in 59 patients. Ninety-eight patients were treated with antiepileptic drugs (AEDs): carbamazepine (CBZ) or valproate (VPA). The study showed that, in Chinese children, BRE is remarkably characteristic in its clinical and EEG presentation. Although BRE is usually benign in terms of ease of control with AEDs and spontaneous seizure remission, for those patients with a high frequency of seizures, AEDs should be prescribed positively.     

Childhood epilepsy with occipital paroxysms and benign nocturnal childhood occipital epilepsy

Two types of childhood epilepsy have recently been reported: childhood epilepsy with occipital paroxysms, and benign nocturnal childhood occipital epilepsy. This article reports the clinical evolution, electroencephalographic (EEG) changes, and response to therapy of eight children with childhood epilepsy with occipital paroxysms (five boys and three girls, aged from 1 1/12 to 8 years) and eight children with benign nocturnal childhood occipital epilepsy (six boys and two girls, aged from 1 4/12 to 8 3/12 years). A careful clinical and EEG follow-up of at least 7 years was carried out for all patients. At the end of follow-up, all but one of the patients with childhood epilepsy with occipital paroxysms were seizure-free, and only two were still receiving anticonvulsant drugs. All but three children had a normal EEG, and normal mental development was observed in all but two cases. Patients with benign nocturnal childhood occipital epilepsy had a good long-term prognosis; all but two children with benign nocturnal childhood occipital epilepsy had a normal EEG. These two patients showed learning disabilities and poor school performances, and required remedial education. Therefore, although childhood epilepsy with occipital paroxysms and benign nocturnal childhood occipital epilepsy are two different types of epilepsy, the long-term prognosis seems to be similar.
