青少年肌阵挛性癫痫的研究动态 总被引:3,自引:0,他引:3
青少年肌阵挛性癫痫(juvenile myoclonic epilepsy,JME)是一种特发性全身性癫痫综合征,以肌阵挛发作为突出表现.Herpin于1867年首次描述了1个JME病例,该病例为一13岁的男孩,开始表现为上身抽搐,3个月后进展为"完全的癫痫发作". 相似文献

Fourteen patients with juvenile myoclonic epilepsy (JME) were treated with a single low dose of a sustained-release preparation
of sodium valproate (VPA, 500 mg daily). The mean age of the onset of the low dose treatment was 19.2 years (range 14–26).
Before this treatment, six patients had been treated with high dose VPA for a period of more than 2 years, three patients
for 1 to 2 years, three patients less than 1 year and two patients initiated the treatment from the begining with a low dose.
The mean duration of low dose treatment is 35.6 months (range 25–59 months). (All patients are still under medication). Generalized
tonic-clonic and absence seizures were controlled in all patients. Myoclonic jerks relapsed only in one patient, a young mother
who was looking after her newly born baby and was deprived of sleep. No adverse reactions have been reported. We suggest that
JME patients can effectively be treated with single low VPA dose (500 mg daily), while at the same time seizure precipitating
factors, such as sleep deprivation and alcohol ingestion, should be avoided.

OBJECTIVES: Phenotypic analysis of juvenile myoclonic epilepsy (JME) is presented to document the variations in disease expression. MATERIAL AND METHODS: Information on seizure type and frequency, seizure precipitating factors, electro-encephalographic (EEG) data, response to antiepileptic drugs (AEDs) and family history was collected on 500 Indian probands and 61 relatives with JME. RESULTS: The overall clinical features, EEG characteristics, and familial occurrence were similar to other reports. JME probands and relatives having absences (56 of 561, 10%), those with only myoclonic jerks (MJ) or MJ with one generalized tonic clonic seizure (GTCS) in remission without treatment (five of 561, 1%) and those who required valproic acid (VPA) and another AED for seizure control (19 of 561, 3%) are examples of differential disease expression within JME. Seizures among those having photoparoxysmal response (PPR) on EEG responded very well to VPA alone while those with all three seizure types (MJ, GTCS and absences) were poor responders. CONCLUSIONS: Recognition of clinical 'subtypes' among JME could have therapeutic implications and help improve JME phenotypic characterization for molecular studies. 相似文献

We report on two siblings who presented with juvenile myoclonic epilepsy, and in whom myoclonic jerks of the right arm and hand were also triggered by writing tasks. Both patients underwent intensive video-electroencephalography monitoring, with simultaneous neuropsychological tests. In both patients, reflex epileptic myoclonus was more easily triggered by writing that required a higher degree of concentration. Conversely, other cognitive tasks, such as reading, typing, thinking, or calculation never elicited any seizures or myoclonus. Valproate was effective in controlling both spontaneous and reflex epileptic seizures. The results of this study further support the notion that 'praxis-induced' reflex epilepsy precipitated by specific stimuli occurs in the context of idiopathic generalized epilepsy. Our results also illustrate that writing tasks are more effective in eliciting seizures when they require higher levels of concentration and mental elaboration. 相似文献

Hirayama disease (HD) is rare, but benign anterior horn cell disease, predominantly affecting young men. One of the symptoms, besides weakness, is abnormal movement in the hand. Juvenile myoclonic epilepsy (JME) is one of the most common types of generalized epilepsies and can be recognized by a myoclonic jerk and electroencephalography (EEG) features. We report the case of a 19-year-old male who had HD, with unilateral abnormal movement in the hand, which was diagnosed as JME. We should consider performing an EEG in patients with HD, who present with atypical hand movements, in order to differentiate it from seizure. 相似文献

PurposeTo evaluate clinical features of probands with juvenile myoclonic epilepsy (JME) and affected members of their families in order to study clinical genetics of JME.MethodThirteen unrelated families with at least two members with history of seizures were identified; clinical and genealogic data were collected from JME probands and family members.ResultsAll probands had myoclonic and generalized tonic–clonic seizures (GTCS), while absences occurred in 25% of them. The average age of seizure onset was 13 years. Totally 22 members from 13 families had history of seizures with average age of seizure onset at 18 years. Ten family members had JME, three had epilepsy with GTCS, two had juvenile absence epilepsy, one had adult onset myoclonic epilepsy and six of the affected individuals had unclassified type of epilepsy. In five families, JME was the solely clinical feature. JME dominated among siblings, while phenotypic heterogeneity was observed in second and third degree relatives. In three multi-generation families, members with adult onset genetic generalized epilepsies (GGE) were identified.ConclusionWe found phenotypic heterogeneity regarding epilepsy type and age of seizure onset. Using pedigree analysis, we found no evidence for preferential maternal or any other distinctive inheritance pattern. Further study is needed to confirm and clarify the results. 相似文献

PURPOSE: To document whether the mechanisms responsible for myoclonic jerks in juvenile myoclonic epilepsy (JME) are similar to those causing other forms of myoclonus. METHODS: We studied somatosensory evoked potentials, the conditioning effect of cutaneous afferents on motor potentials evoked by transcranial magnetic stimulation (TMS), and intracortical inhibition and facilitation in response to paired TMS in a group of nine patients with JME and 20 normal controls. RESULTS: Intracortical inhibition was abnormal, whereas cortical somatosensory evoked potentials and TMS conditioned by cutaneous afferents were unaltered in JME patients. CONCLUSIONS: Abnormal processing of cutaneous afferents would not appear to contribute to myoclonus in JME. 相似文献

目的研究青少年肌阵挛性癫痫(JME)的临床特点及导致误诊的主要原因。方法对61例JME患者的临床和脑电图(EEG)资料进行回顾性分析。结果肌阵孪是最常见的首发症状,其次为肌阵挛加全身强直一阵孪发作(GTCS)。导致误诊最常见的原因是医师对肌阵挛发作缺乏认识,其次是临床和EEG的非对称性表现。结论JME的正确诊断依赖于医师对此综合征的深刻了解,EEG只能作为辅助诊断工具。 相似文献

Drug treatment of juvenile myoclonic epilepsy (JME) is mainly based on clinical experience and prospective and retrospective studies, with little evidence from randomized clinical trials. There are almost no head-to-head comparisons between old and new antiepileptic drugs (AEDs). Valproate is the drug of the first choice in men with JME. In women, lamotrigine (LTG) should be preferred regarding teratogenicity and side effects of valproate. Levetiracetam (LEV) is also effective. Recent data suggest that it may soon be used as first line treatment. Some AEDs can aggravate JME. In addition to AEDs, nonpharmacological treatments are important in JME. JME usually requires lifelong treatment because seizures nearly always return after withdrawal of therapy. 相似文献
